Business Terms of Service

Article 1. Scope and Application

1. These Terms of Service (the “Terms”) set out the conditions governing the use of services provided by Sola Studio (“Sola Studio,” “we,” “us,” or “our”) to corporations, unincorporated organizations, sole proprietors, and other persons using our services for business purposes (each, a “Client”).
2. These Terms apply to Sola Studio’s business services generally, including services for clients in Japan and clients located outside Japan.
3. These Terms apply, at a minimum, to the following service models:
   1. Consulting-Type Services provided on a fixed-content / fixed-fee basis;
   2. Report-Type Services provided on an asynchronous basis, where reports, structured outputs, or other shared materials are returned based on detailed forms, submission of materials, or other required inputs; fees may be fixed or individually quoted from a stated minimum depending on the service;
   3. Scoped Services provided within a defined scope, assumptions, exclusions, and related conditions; and
   4. Ongoing Support Services provided on the basis of a defined period, role, time allocation, or support frame.
4. These Terms do not apply to personal / consumer services. Separate terms may apply to such services.
5. Where we separately provide service descriptions, estimates, proposals, order documents, application guidance, individual contracts, Statements of Work / Order Forms, service-specific conditions, payment instructions, or other written or electronic terms, those materials supplement these Terms.

Article 2. Definitions

Unless the context requires otherwise, the following terms have the meanings set out below:

1. “Client” means any corporation, unincorporated organization, sole proprietor, or other person applying for or using our services for business purposes.
2. “Individual Agreement Documents” means any estimate, proposal, individual contract, Statement of Work / Order Form, service-specific conditions, purchase order, order form, payment instruction, or other written or electronic agreement that sets project-specific terms between Sola Studio and the Client.
3. “Consulting-Type Services” means services provided under a predefined package structure, fixed fees, and a fixed delivery framework.
4. “Report-Type Services” means services provided primarily on an asynchronous basis, based on detailed forms, submission of materials, responses, or other required inputs, and under which we return structured outputs, reports, observations, or other shared materials. Fees for Report-Type Services may be fixed or individually quoted from a stated minimum, as set out in the relevant Service-Specific Conditions.
5. “Scoped Services” means services provided within a defined scope, work content, assumptions, exclusions, shared outputs, review period, and other necessary conditions.
6. “Ongoing Support Services” means services provided continuously on the basis of a defined period, role, time allocation, or support frame.
7. “Shared Work Output” means any materials, documents, UX or messaging notes, review findings, screen proposals, wireframes, specification-related outputs, reports, configuration notes, code, prototypes, or any other content shared, sent, or presented by us in connection with the services.
8. “Commencement” means the point at which we begin substantive work to prepare for or carry out the services, including investigation, organization, design, preparation, implementation, meetings, or similar work.
9. “Sharing of Work Output” means the point at which we share or present Shared Work Output by email, file sharing, shared documents, online meeting, repository, or any other reasonable method.
10. “Review Period” means the period specified in Article 20 during which the Client may review Shared Work Output and notify us of comments or issues.
11. “Minor Revisions” means correction of typographical errors, supplementation of obvious omissions, small adjustments consistent with already agreed content, or other revisions we reasonably determine to be minor.
12. “Service-Specific Conditions” means project-specific or service-specific conditions set out in any Individual Agreement Documents.
13. “Lapse” means the end of the progress eligibility for a relevant application or service arising where the Client fails, within the period stated in the relevant Service-Specific Conditions, to provide required responses, submit required materials, cooperate in scheduling, or provide other required cooperation.
14. “Reserved Monthly Capacity” means the number of service hours reserved for an Ongoing Support Service for a particular month under the applicable Individual Agreement Documents.

Article 3. Relationship Between These Terms and Individual Terms

1. These Terms set out the general conditions applicable to our business services.
2. The specific service content, scope, assumptions, exclusions, shared outputs, review terms, scope of Minor Revisions, payment method, payment timing, currency, contract period, renewal terms, settlement terms upon termination, intellectual property exceptions, and other project-specific conditions may be set out in Individual Agreement Documents.
3. If any Service-Specific Conditions expressly state terms that differ from these Terms, those Service-Specific Conditions will prevail only for the relevant service or engagement and only to the extent of the express inconsistency.
4. Even where Individual Agreement Documents apply, the provisions of these Terms regarding confidentiality, intellectual property, limitation of liability, governing law, and other provisions that are intended to apply generally will continue to apply unless expressly stated otherwise.

Article 4. Nature of the Services

1. Our services are professional advisory, implementation, and related support services, including advisory, structuring, design support, review, research, implementation, implementation support, documentation support, coordination support, and related services.
2. Unless expressly stated otherwise, our services are not provided on the basis of an obligation to deliver a completed result. Rather, they consist of the performance of services with due care within the agreed scope.
3. Unless we expressly guarantee otherwise, we do not guarantee revenue increase, investment outcomes, internal approvals, product launch outcomes, production release, merge, deployment, legal compliance, regulatory compliance, accessibility compliance, formal audit results, certification, conformance documentation, quality improvement, schedule achievement, or any other specific result expected by the Client.
4. Any materials, proposals, review comments, structured outputs, shared outputs, or other results we provide do not replace the Client’s own business, legal, implementation, procurement, or other final decision-making.
5. The specific service conditions, review mechanics, completion logic, payment terms, and allocation of responsibility may differ depending on the relevant service model and Service-Specific Conditions.
6. Unless expressly stated otherwise, any materials, proposals, structured design outputs, review findings, screen proposals, specification-related outputs, prototypes, or other Shared Work Output we share are provided for the purpose of structuring, advising, reviewing, considering, or sharing within the objective and scope of the relevant service, and do not constitute final deliverables, final confirmed specifications, detailed design documents, implementation instructions, or legal, technical, or business assurance materials, nor do they mean that we assume responsibility for delivering any such completed deliverable.
7. Where our services involve UX or messaging notes, structure for pages, flows, forms, journeys, or other customer-facing digital touchpoints, wireframes, copy proposals, wording review, localization-related context, translation adjustment, review findings, or similar communication-related support, such services are provided within the agreed scope and for the purpose of supporting user experience, messaging, structure, clarity, information order, decision flow, and related project decisions. Unless expressly agreed otherwise, they do not constitute professional translation services, full localization delivery, legal review, regulatory review, compliance review, advertising approval review, tax advice, or any equivalent regulated or specialist service.
8. Where legal or policy pages, terms of service, privacy policies, cookie policies, refund or cancellation terms, disclaimers, regulated notices, contractual terms, or similar legal or policy wording are relevant to a project, the Client remains responsible for preparing, translating, reviewing, approving, and maintaining such wording. Unless expressly agreed otherwise, Sola Studio does not translate, rewrite, validate, review, or confirm the legal sufficiency, regulatory compliance, translation quality, publication readiness, or enforceability of such wording.
9. Sola Studio may indicate the possible placement, link path, visibility, placeholder, or user-flow position of legal or policy pages or similar materials where relevant to the agreed service. Such indication does not mean that Sola Studio has reviewed or approved the wording itself or that the wording is legally, regulatorily, commercially, or operationally sufficient.
10. If Client-provided information, source materials, factual details, pricing, support terms, specifications, legal conditions, approvals, or other necessary inputs are incomplete, unavailable, unclear, or not yet confirmed, Shared Work Output may include assumptions, placeholders, indicative wording, notes, or items requiring Client confirmation. Sola Studio is not responsible for creating or verifying facts, claims, legal conditions, pricing, specifications, or other Client-side information that has not been provided or confirmed by the Client.

Article 5. Service Models

1. Consulting-Type Services are services provided under a predefined package structure, fixed fees, and a fixed delivery framework.
2. Report-Type Services are services provided on an asynchronous basis, based on detailed forms, submission of materials, or other required inputs, and under which reports, structured outputs, or other shared materials are provided. Fees may be fixed or individually quoted from a stated minimum, as set out in the relevant Service-Specific Conditions.
3. Scoped Services are services provided within a defined scope, assumptions, exclusions, shared outputs, review period, and related conditions.
4. Ongoing Support Services are services provided continuously on the basis of a defined period, role, time allocation, or support frame.
5. Contract-formation timing, payment conditions, response deadlines, scheduling deadlines, completion logic, review mechanics, and handling upon interruption or termination may differ depending on the relevant service model.

Article 6. Individual Service Content and Naming

1. The name, content, scope, fees, payment terms, shared outputs, Review Period, exclusions, and other Service-Specific Conditions for each individual service will be set out in the relevant service page, application screen, estimate, proposal, payment instruction, service-specific conditions, or other written or electronic materials separately provided by Sola Studio.
2. Service pages, application screens, or other guidance may use a package-style service name covering multiple stages or related services. Even in such cases, the specific content of the service, what is included, what is excluded, the applicable fees, and other conditions will be determined by the Service-Specific Conditions separately provided by Sola Studio.
3. Even if an individual service has a different service name, display name, internal management name, or service_key, the service covered and the applicable conditions will be identified by the service page, application screen, estimate, payment instruction, or other Service-Specific Conditions presented to the Client.
4. Each service includes only the items expressly stated by Sola Studio. Any creation or sharing of work outputs, implementation, design, investigation, review, ongoing support, maintenance, stakeholder handling, or other matters not expressly stated in the relevant service page, application screen, estimate, proposal, payment instruction, service-specific conditions, or other materials separately provided by Sola Studio are not automatically included in that service.

Article 7. Contract Formation

1. For Consulting-Type Services, a contract is formed when the Client submits an application, order, or similar request and Sola Studio accepts it.
2. However, for any fixed-fee service requiring advance payment where the relevant Service-Specific Conditions expressly state that the contract is formed upon completion of payment, the contract is formed when the specified payment is completed.
3. For Report-Type Services, provided at a fixed fee, paragraph 2 applies unless the relevant Service-Specific Conditions expressly provide otherwise. For Report-Type Services provided at an individually quoted fee, contract formation is governed by the applicable Service-Specific Conditions. For Consulting-Type Services and Report-Type Services, a separate contract is not normally required in the standard flow unless expressly stated in the relevant Service-Specific Conditions or separately requested and agreed.
4. For Scoped Services and Ongoing Support Services, a contract is formed only when the parties enter into a separate written or electronic agreement, such as an individual contract, Statement of Work / Order Form, or service-specific agreement.
5. Estimates, proposals, draft SOWs, pre-contract consultation materials, rough estimates, initial proposals, and similar pre-contract materials do not by themselves create any obligation for Sola Studio to enter into a contract or provide services, unless expressly stated otherwise.
6. Any rough estimate, preliminary terms, or initial proposal provided before execution of an NDA are reference information before the formal terms are finalized and may be revised, updated, or changed by the formal terms separately presented later.
7. Even where an inquiry or application has been submitted, Sola Studio may decide not to proceed with contract formation based on project fit, assumptions, feasibility, payment conditions, legal, tax, sanctions, export-control, data-handling, security, information-management, operational, jurisdictional, or other relevant circumstances.

Article 8. Conditions for Service Commencement

1. Even after contract formation, Sola Studio may defer commencement or continuation of services until required preliminary materials, required information, required access rights, required communication arrangements, required preconditions, responses to designated forms, required scheduling cooperation or other prerequisite actions specified in the relevant Service-Specific Conditions, and/or agreed payments have been completed.
2. Where specified by Sola Studio, the Client must complete required advance payment, initial fees, reserved-capacity fees, monthly fees, or other agreed payments before service commencement.
3. Sola Studio may postpone or suspend commencement, sharing of work outputs, meetings, access provision, review work, or other service actions until required payment has been confirmed.

Article 9. Client Cooperation Obligations

1. The Client must provide, in a timely and accurate manner, all information, materials, URLs, target items, background context, decisions, responses, approvals, accounts, access rights, connection information, internal coordination, scheduling cooperation, and other assistance reasonably necessary for the services.
2. If the Client fails to provide sufficient cooperation due to lack of information, lack of materials, unclear assumptions, inconsistent instructions, delayed approvals, unavailable stakeholders, restricted access, or other Client-side circumstances, Sola Studio is not responsible for resulting delay, rework, reduced precision, work constraints, increased burden, or similar effects.
3. Where source materials, background explanations, approved summaries, translations, terminology, brand guidance, pricing information, support conditions, legal or policy wording, or other Client-side materials are necessary for the relevant service, the Client is responsible for providing them in a form that is accurate, sufficiently complete, lawful to share, and reasonably understandable for the agreed service. If materials are provided in a language or format that requires additional translation, explanation, preparation, or confirmation, this may affect the scope, schedule, fees, precision, or specificity of the services.
4. In such cases, Sola Studio may, where appropriate, adjust schedules, stop work, propose additional fees, switch to another service model, issue an additional estimate, or take other reasonable measures.
5. The Client is responsible for ensuring that any materials, information, data, content, URLs, accounts, credentials, or other items shared with Sola Studio are lawfully shared, accurate, complete, and do not infringe third-party rights.
6. The Client is responsible for identifying in advance any jurisdiction-specific legal, regulatory, privacy, data protection, consumer protection, accessibility, procurement, industry-specific, or internal compliance requirements that the Client expects Sola Studio to take into account. Unless expressly agreed otherwise, Sola Studio does not assume responsibility for identifying or satisfying such Client-side or jurisdiction-specific requirements.
7. If the Client’s breach of paragraph 5 causes disputes with third parties, rights claims, deletion or replacement work, project suspension, or other issues, and as a result Sola Studio must undertake reasonable additional work, Sola Studio will not be responsible for such issues and may charge the Client for the reasonable cost of that additional work.
8. If the Client fails, within the period stated in the relevant Service-Specific Conditions, to provide required responses, submit materials, provide confirmations, approvals, scheduling cooperation, or other required cooperation, Sola Studio may defer commencement or continuation of the relevant service, suspend progress, treat the relevant application or service as lapsed, or otherwise end the relevant application or service in accordance with the relevant Service-Specific Conditions.
9. In such cases, whether any prepaid amounts are refundable, whether the service may be resumed, whether rescheduling may be allowed, and any other conditions will be governed by the relevant Service-Specific Conditions.
10. The Client must not use the services in connection with any activity, person, entity, country, sector, product, data, transaction, or project that is subject to sanctions, export-control restrictions, or other legal restrictions applicable to either party. The Client must promptly notify Sola Studio if it becomes aware of any such risk.

Article 10. Communication Methods

1. Communications, submission of materials, confirmations, review comments, revision requests, sharing of work outputs, and other exchanges necessary for performance of the services shall be conducted by methods separately specified by Sola Studio.
2. Such methods may include forms, email, online meetings, cloud storage, shared documents, chat tools, and other methods designated by Sola Studio.
3. The Client may submit or share information, materials, communications, and related items through forms, scheduling tools, shared documents, cloud services, payment-related services, or other external tools designated by Sola Studio.
4. If the Client sends information, materials, comments, or requests through methods not designated by Sola Studio, Sola Studio will not be responsible for any failure to notice or reflect them unless caused by our willful misconduct or gross negligence.

Article 11. Records and Recording

1. For purposes reasonably necessary for service provision, operational quality, safety, dispute prevention, harassment response, or similar reasons, Sola Studio may record, retain, or otherwise preserve parts of meetings, calls, screen-sharing sessions, communications, or other interactions.
2. Where notice, explanation, or consent is required by law or operational practice before such recording or retention, Sola Studio will take the necessary steps.

Article 12. Harassment Response

1. The Client shall take appropriate measures, to the extent necessary, to ensure that conduct occurring in connection with the engagement does not harm the working environment of Sola Studio or anyone working for or on behalf of Sola Studio.
2. The Client must not engage in conduct toward Sola Studio that is based on an abusive or superior position, or that otherwise exceeds what is necessary and reasonable for performance of the engagement, where such conduct harms the working environment of Sola Studio or anyone working for or on behalf of Sola Studio.
3. If Sola Studio or anyone working for or on behalf of Sola Studio raises a concern, makes a report, or provides information regarding harassment in connection with the engagement, the Client shall, to the extent reasonably necessary, take reasonable steps such as fact-finding, hearing from relevant persons, corrective measures, recurrence-prevention measures, or other appropriate responses.
4. The Client must not subject Sola Studio or anyone working for or on behalf of Sola Studio to adverse treatment on the grounds that they raised a concern relating to harassment, cooperated with a response to such concern, or provided information during any related fact-finding process.
5. If harassment by the Client, refusal to cooperate, repeated intimidating conduct, or similar circumstances lead Sola Studio reasonably to determine that continuation of the contractual relationship has become difficult, Article 29 will apply.

Article 13. Consideration for Pregnancy, Childbirth, Childcare, and Caregiving

1. Where the Freelance Transactions Act of Japan or other applicable law applies, and the engagement falls within a category for which such consideration is legally required, the Client shall, upon request from Sola Studio, discuss necessary consideration appropriate to Sola Studio’s circumstances in order to support the balancing of work with pregnancy, childbirth, childcare, or caregiving.
2. Such consideration may include, where reasonable in light of the nature and status of the engagement, adjustments to working methods, communication methods, meeting times, expected timing, sharing arrangements, or other comparable operational arrangements.
3. Where such a request is made, the Client shall consider it in good faith, taking into account the nature of the engagement, project status, operational needs, and other relevant circumstances, and shall discuss in good faith whether and to what extent reasonable accommodation is possible.
4. The Client must not subject Sola Studio to adverse treatment on the grounds that Sola Studio requested consideration in relation to pregnancy, childbirth, childcare, or caregiving.
5. Even where the legal obligation described in paragraph 1 does not directly apply, the Client is expected to make reasonable efforts, where practicable, to respond flexibly in light of the nature of the engagement and the content of Sola Studio’s request.

Article 14. Accuracy of Submitted Information

1. The Client shall use reasonable efforts to ensure that information submitted through initial forms, detailed forms, application forms, meetings, emails, contract procedures, payment procedures, or other channels is true, accurate, and sufficiently complete at the relevant time.
2. Sola Studio may rely on information provided by the Client when assessing project suitability, preparing estimates, deciding whether to contract, structuring the services, conducting reviews, and performing related work.
3. If the Client conceals important facts or provides inaccurate or misleading information, and that results in additional burden, rework, delay, misunderstanding, or other disadvantage to Sola Studio, we may charge additional fees, revise the schedule, suspend work, terminate the contract, or take other reasonable measures.

Article 15. Pre-NDA Information-Sharing Rules

1. As a general rule, Sola Studio does not assume the handling of highly confidential information, sensitive information, regulated information, or other information requiring heightened protection before an NDA or similar separate arrangement is in place.
2. In particular, for Scoped Services, where confidential information is needed for detailed review, formal estimation, or formal scope definition, such information-sharing will generally require an NDA or other necessary condition-setting beforehand.
3. If the Client shares information before execution of an NDA or before such necessary condition-setting, Sola Studio will not assume that the information was shared on the basis that it would automatically be treated as confidential, unless we expressly agree to receive it as confidential.
4. For Consulting-Type Services, Report-Type Services, and other services that do not, as part of their standard flow, require a separate NDA, the confidentiality provisions of these Terms apply as the parties' baseline confidentiality framework. Where the Service-Specific Conditions for a particular Report-Type Service expressly require an NDA, those conditions govern.
5. If a separate NDA or similar confidentiality agreement is executed, that agreement will prevail with respect to the information and period it covers.

Article 16. Confidentiality

1. Each party shall use non-public information disclosed by the other party in connection with the services only to the extent necessary for evaluating, contracting for, performing, or reviewing the relevant engagement, and shall not disclose or leak such information to any third party without prior consent.
2. The following are not confidential information:
   1. information already publicly known at the time of disclosure;
   2. information that becomes public after disclosure through no fault of the receiving party;
   3. information lawfully possessed by the receiving party before disclosure;
   4. information lawfully obtained from a third party with proper authority; or
   5. information independently developed or acquired without reference to the other party’s confidential information.
3. Where disclosure is required by law, court order, governmental authority, or similar public requirement, the receiving party may disclose the relevant information to the minimum extent necessary, to the extent legally permissible after notifying the other party where possible.
4. Sola Studio may share confidential information with subcontractors, specialists, professional advisors, or other third parties to the extent reasonably necessary for performance of the services, provided that such parties are bound by confidentiality obligations equivalent to or stronger than those in these Terms or any applicable NDA.
5. Personal information shall also be handled in accordance with our Privacy Policy and applicable law.
6. If a separate NDA exists, it will prevail over this Article to the extent of any inconsistency or greater specificity.
7. Where no separate NDA exists, the confidentiality obligations in this Article will survive for three (3) years after the end of the relevant service or contractual relationship; provided, however, that information that remains non-public and reasonably requires continued protection by its nature, or under applicable law, shall continue to be protected for so long as such need persists.
8. For clarity, the Client acknowledges and authorizes the use and related processing described in Article 26, subject to the conditions stated there and any applicable NDA, data-processing agreement, Service-Specific Conditions, and applicable law. Use in accordance with Article 26 does not by itself constitute an unauthorized disclosure under this Article.

Article 17. Out-of-Scope Work and Additional Requests

1. Requests exceeding the agreed scope, assumptions, dependencies, time allocation, review framework, Minor Revision range, exclusions, or service model may be handled by Sola Studio as:
   1. separately billable additional work;
   2. paid consultation or another paid support slot;
   3. a new SOW, individual agreement, or service-specific agreement; or
   4. transition to an Ongoing Support model where more appropriate.
2. Sola Studio is under no obligation to absorb such additional work within the originally agreed fee.
3. New functions, new screens, new reviews, creation of new materials, explanatory documents, additional Shared Work Output, additional investigation, additional meetings, repeated explanations, stakeholder coordination, additional implementation, additional documentation, additional UX or messaging notes, translation or copy work beyond the agreed scope, work arising from third-party tools, platform constraints, repository or deployment constraints, or other burden not included in the original agreement may be treated as additional work.
4. If Sola Studio reasonably determines that previously shared review findings, research results, structured materials, existing materials, external audit results, issue lists, or other information are no longer appropriate to rely on as originally assumed due to subsequent specification changes, screen changes, code changes, operational changes, the passage of time, or similar circumstances, Sola Studio may propose additional review, re-review, scope restructuring, an additional estimate, or other reasonable steps.
5. If major changes to assumptions, requests, materials, or scope make continuation under the original service model or original agreed conditions unreasonable, Sola Studio may propose revised terms, a return to an earlier stage, contract restructuring, or termination.
6. Ongoing Support Services do not mean unlimited task acceptance, always-on immediate response, unlimited meeting participation, or effective staff augmentation. They are provided only within the agreed role, time allocation, period, and support model.
7. Unless expressly agreed otherwise, Ongoing Support Services and other services do not include participation in meetings outside the agreed schedule, time allocation, or scope; attendance at social, networking, relationship-building, dining, or similar events; preparation of meeting minutes; meeting facilitation; project coordination, task tracking, or general project management functions; coordination among the Client’s internal or external stakeholders or acting as the Client’s point of contact; mentorship; training; internal persuasion; or other tasks not directly related to the professional services provided by Sola Studio.
8. For Ongoing Support Services, work beyond the Reserved Monthly Capacity will be performed only where Sola Studio has confirmed availability and the parties have agreed in advance, in writing or by electronic means, on the requested work, the maximum number of additional hours, and the applicable rate or fee.
9. Unless the applicable Service-Specific Conditions expressly state otherwise, additional hours for Ongoing Support Services are billed at the standard additional-hours rate stated in the relevant service page or Individual Agreement Documents. A discounted rate applicable to a larger monthly-capacity option does not apply retroactively to separately added hours.
10. Where the monthly fee is prepaid, additional hours that could not reasonably be determined in advance will normally be confirmed at month-end and invoiced separately in accordance with Article 18. Where the monthly fee is paid after the relevant month, additional hours may be included in the same monthly invoice.
11. Depending on the number of additional hours, timing of the request, previous payment history, outstanding exposure, or other relevant circumstances, Sola Studio may require advance payment of all or part of the additional fee before beginning the additional work. If additional work is expected to recur, the parties will review whether to change the Reserved Monthly Capacity for a later month.

Article 18. Payment Methods and Terms

1. The Client shall pay fees, costs, taxes, and other agreed amounts in accordance with the payment terms separately specified by Sola Studio or otherwise agreed between the parties.

2. Specific payment conditions—such as payment method, currency, payment timing, installment ratio, billing cycle, and whether a platform is used—shall be set out in the relevant Individual Agreement Documents or payment guidance.

3. Unless expressly stated otherwise, fees displayed or quoted by Sola Studio are exclusive of applicable taxes, duties, withholding taxes, Japanese consumption tax, VAT, GST, bank charges, remittance fees, payment processing fees, and other payment-related costs. If fees are displayed or quoted as tax-inclusive, or if another treatment is expressly stated, that statement will apply.

4. The taxes, charges, fees, and other payment-related costs described in the preceding paragraph shall be borne by the Client, except where applicable law requires otherwise.

5. For transactions to which Japanese consumption tax applies, Japanese consumption tax will be handled in accordance with the applicable estimate, invoice, payment guidance, or other Individual Agreement Documents.

6. For services supplied to non-Japan business clients, Sola Studio may not charge Japanese consumption tax where the transaction qualifies as an export-exempt transaction under Japanese consumption tax law. Even in such cases, any VAT, GST, reverse charge accounting, filing, reporting, or other local tax treatment or payment obligation in the Client’s jurisdiction remains the Client’s responsibility.

7. If the Client is legally required under applicable law to withhold tax or make any other deduction from a payment to Sola Studio, the Client must notify Sola Studio in advance and promptly provide official or reasonably sufficient documentation showing the legal basis, amount, and details of the withholding or deduction. Except for legally required withholding or deductions, the Client may not deduct bank charges, remittance fees, payment processing fees, or other costs from the amount invoiced by Sola Studio.

8. Fees displayed or quoted by Sola Studio for international business services are shown in USD, unless another display treatment is expressly stated. Payment is accepted in USD or JPY only. If payment in JPY is accepted, the amount payable will be calculated from the USD-listed or USD-quoted amount using the exchange rate in effect at the time of invoicing, unless another timing is expressly stated in the applicable estimate, invoice, payment guidance, or other Individual Agreement Documents.

9. USD payments will generally be processed through Stripe or another online payment method specified by Sola Studio, unless expressly stated otherwise. If JPY payment is accepted, payment by bank transfer may be made available on request, subject to the applicable payment guidance or other Individual Agreement Documents. However, for Ongoing Support Services, higher-value engagements, client-side purchasing or compliance requirements, Japan-side billed engagements, or other relevant circumstances, Sola Studio may specify Deel, bank transfer, international remittance, or another payment method or platform on a case-by-case basis.

10. Sola Studio may adopt advance payment, installment payment, milestone payment, monthly payment, reserved-capacity prepayment, platform-based recurring billing, or other payment structures on a case-by-case basis.

11. For Ongoing Support Services, the initial monthly fee and fees after continuation are payable in advance by default. A different billing cycle, including post-payment, applies only where Sola Studio accepts that arrangement and the parties agree to it in advance in writing or by electronic means. The availability of post-payment for one engagement or Client does not require Sola Studio to offer it for another engagement, renewal, or Client.

12. Where post-payment is agreed for an Ongoing Support Service:

    1. for an engagement billed under Japan-market conditions, the standard due date for a month’s fee is the fourteenth (14th) day of the following month; and
    2. for an engagement billed under international-business conditions, the standard due date is fourteen (14) calendar days after the invoice date. In each case, the invoice or applicable Individual Agreement Documents will state the specific calendar date on which payment is due. If a due date for payment by bank transfer falls on a day on which the relevant financial institutions are closed, payment is due on the immediately preceding banking business day, unless otherwise expressly agreed.

13. Additional hours for Ongoing Support Services will be invoiced under the timing stated in Article 17. Unless advance payment is required under Article 17(11) or different terms are expressly agreed, additional hours for a prepaid monthly engagement will be confirmed at month-end and paid by the applicable due date in paragraph 12. For a post-paid monthly engagement, the monthly fee and additional-hours fee may be included in the same invoice.

14. A change from advance payment to post-payment changes only the timing of payment. It does not convert a reserved-capacity monthly fee into billing based solely on hours actually requested, consumed, or used by the Client.

15. For Ongoing Support Services, where both parties agree and Sola Studio determines that it is the better operational fit, recurring billing and payment handling may be arranged through Deel or another designated platform.

Article 19. Late Payment and Suspension

1. If the Client fails to make payment by the applicable due date, Sola Studio may issue a late-payment notice and may suspend all or part of the services, withhold sharing of work outputs, postpone meetings, reviews, or other actions, or defer commencement or continuation until payment is confirmed.
2. For Ongoing Support Services, Sola Studio may also withhold or release any capacity provisionally intended for a later month and is not required to continue providing services while an earlier amount remains unpaid.
3. Sola Studio will not be responsible for schedule changes, delays, loss of capacity, or other progress effects resulting from a suspension or withholding of capacity under this Article.
4. If late payment continues, or if Sola Studio reasonably determines that there is a serious concern regarding the Client’s willingness or ability to pay, Sola Studio may terminate or end the relevant contract or engagement.
5. Even where services are suspended, terminated, or ended, the Client remains responsible for fees and costs corresponding to work already performed, reserved capacity, scheduled slots, approved external costs, non-cancelable costs, rescheduling costs, and other costs already incurred or reasonably committed by Sola Studio.
6. Sola Studio may charge late payment interest or similar amounts where permitted by the applicable Individual Agreement Documents or applicable law.

Article 20. Review Period, Minor Revisions, and Service Completion

1. For Report-Type Services, Scoped Services, and any other services for which a Review Period is expressly stated in the relevant Service-Specific Conditions, Sola Studio will, after a final sharing step appropriate to the service—such as sending final shared materials, sharing final work output, or another final sharing step appropriate to the relevant service—provide a Review Period for the Client.
2. The Review Period is five (5) calendar days by default, unless a different period is expressly stated in the relevant estimate, SOW / Order Form, individual contract, or other Service-Specific Conditions.
3. If the Client believes there are matters that qualify for Minor Revisions or other deficiencies, the Client must notify Sola Studio of them specifically and in writing or by electronic means within the Review Period. Where reasonably possible, such comments should be submitted together in one batch.
4. If no specific comments are received within the Review Period, Sola Studio may treat its service obligations for the relevant service or shared output as completed.
5. Sola Studio will, in principle, respond once to comments received within the Review Period to the extent they qualify as Minor Revisions.
6. The following do not qualify as Minor Revisions:
   1. additional scope;
   2. additional investigation, consideration, or analysis;
   3. preparation of new materials, review materials, explanatory documents, or additional Shared Work Output;
   4. additional implementation, design, or documentation;
   5. added stakeholder handling, additional meetings, or repeated explanations;
   6. changes responding to major changes in assumptions;
   7. matters raised after the Review Period; and
   8. comments raised in a fragmented, repeated, or piecemeal manner.
7. Even if the Client submits comments within the Review Period, if those comments fall within any of the items above or amount to a second or later round of revision requests, Sola Studio may treat them as separate paid work or as subject to a separate agreement.
8. For Ongoing Support Services, separate Review Periods or completion events for each individual work output do not automatically apply. Unless otherwise stated in the Service-Specific Conditions, the relevant service period ends upon expiration of the agreed contract period or support period.
9. Where, by the nature of the relevant service, a meeting, report sharing, or another specific point in time is treated as the point at which the service is brought to a close, the relevant Service-Specific Conditions will govern.

Article 21. Cancellation, Early Termination, and Settlement

1. This Article sets out the baseline principles for settlement when a service is cancelled, paused, terminated early, lapses, or is materially changed. Depending on the nature of the engagement, stage of preparation, existence of reserved capacity, external costs, asynchronous handling capacity, or similar factors, different specific terms may be stated in the relevant Service-Specific Conditions.
2. Even if the Client seeks cancellation before service commencement, Sola Studio may charge for already-performed interviews, scope organization, advance preparation, reserved slots, approved external costs, non-cancelable costs, and other reasonable costs already incurred.
3. If, after service commencement, the engagement is paused, changed, postponed, ended, or reduced for reasons attributable to the Client, the Client shall bear fees and costs corresponding to:
   1. work already performed;
   2. work already prepared;
   3. reserved time, reserved slots, or committed work capacity;
   4. approved external costs, tool costs, and non-cancelable costs; and
   5. reasonable costs of rescheduling, winding down, organizing, or ending the engagement.
4. If the Client fails, within the period stated in the relevant Service-Specific Conditions, to provide required responses, submit materials, provide confirmations, cooperate in scheduling, or provide other required cooperation, and as a result the relevant application or service lapses or ends, prepaid amounts may be non-refundable unless the relevant Service-Specific Conditions expressly state otherwise.
5. Because reserved slots, asynchronous handling capacity, advance preparation, payment processing, application handling, or similar arrangements may involve non-recoverable resource commitments, Sola Studio may provide in the relevant Service-Specific Conditions that post-payment cancellations, same-day cancellations, no-shows, lapses, or similar events are subject to refund restrictions or are non-refundable.
6. Whether prepaid amounts are refundable, the amount refundable, whether any pro-rata adjustment applies, how any unpaid installment balance is handled, and other specific settlement conditions may be separately stated in the relevant Service-Specific Conditions in light of the nature and progress of the engagement, reserved capacity, external costs, and similar factors.
7. Fees for Ongoing Support Services are consideration for reserving the agreed monthly support capacity and related availability, and not only for tasks or hours the Client ultimately requests or uses. Client-side underuse, reduction of requests, pauses, early stopping, or termination during a month does not reduce the fee for that month, create a refund, or cause unused hours to roll over to a later month. The same rule applies where post-payment has been agreed.
8. If, for reasons attributable to Sola Studio, Sola Studio is unable to provide all or part of the Reserved Monthly Capacity, Sola Studio will refund the amount corresponding to the unprovided hours or, if the parties agree, credit that amount toward a later month. The amount will be calculated using the hourly rate applicable to the Reserved Monthly Capacity for the relevant month.
9. The initial term of an Ongoing Support Service is one (1) month and does not renew automatically. If the parties wish to continue, they will normally aim to confirm, in writing or by electronic means and by ten (10) business days before the end of the initial term, the Reserved Monthly Capacity and other conditions for the following month. Continuation remains subject to Sola Studio’s availability. If the parties do not agree to continue, the engagement ends upon expiration of the initial term.
10. Once continuation has been agreed, the engagement renews automatically for successive periods of one (1) month. Either party must give notice no later than fourteen (14) calendar days before the next renewal date to terminate the engagement or reduce the Reserved Monthly Capacity. Once the engagement has continued for six (6) months or more, the standard notice period is thirty (30) calendar days before the applicable termination, non-renewal, or capacity-reduction date.
11. A notice received after the applicable deadline in paragraph 10 takes effect from the next renewal date for which the full applicable notice period can be satisfied. An increase in Reserved Monthly Capacity is subject to Sola Studio’s availability and the parties’ prior agreement.
12. Any notice of termination, non-renewal, or capacity reduction under paragraphs 10 and 11 must be provided in writing or by electronic means that allows the notice and its date to be recorded.
13. Paragraphs 9 through 12 do not limit a party’s right to suspend or terminate an engagement for breach, non-payment, illegality, sanctions, harassment, serious information-security concerns, or another ground stated in Article 29 or the applicable Individual Agreement Documents.
14. Sola Studio may, at its discretion, provide a full or partial refund, rescheduling, resumption, or another exceptional accommodation despite the preceding paragraphs; however, any such accommodation does not create any obligation to provide the same accommodation in future cases.
15. Except for a refund calculated under paragraph 8, even where Sola Studio provides a full or partial refund, payment processing fees, remittance fees, foreign exchange-related costs, or other costs arising from third-party services that have already been incurred and are not returned to Sola Studio are not included in the refundable amount and may be deducted from the refund.
16. If an engagement is paused, ended early, lapses, or is materially changed, Sola Studio may share the then-current work on an “as-is” basis.

Article 22. Handling of Collected Information

1. Sola Studio may handle information collected from Clients for the purposes of inquiry handling, project suitability assessment, estimation, contract formation, service delivery, invoicing, payment management, communications, operational management, quality improvement, service improvement, analysis, and other purposes set out in our Privacy Policy.
2. Details regarding the handling of personal information and other information are governed by our Privacy Policy.
3. Nothing in this Article limits the application of Article 15, Article 16, Article 23, or any other provisions relating to confidential information or sensitive information.

Article 23. Sharing of Sensitive, Personal, or Regulated Information

1. If the Client intends to share sensitive personal information, regulated data, highly confidential information, credentials, or other information requiring careful handling, the Client must confirm in advance with Sola Studio the necessity of such sharing and the applicable handling conditions.

2. Where such information is necessary for the services, the parties may separately arrange appropriate conditions such as an NDA, Service-Specific Conditions, access controls, limited viewing scope, or restrictions on sharing methods.

3. If the Client sends such information contrary to the preceding paragraphs, and this results in additional burden, additional handling, risk assessment, deletion work, or similar consequences, Sola Studio may charge additional fees or suspend progress of the engagement.

4. Where the engagement requires Sola Studio to process personal data on behalf of the Client in a manner that requires a data processing agreement, service-provider agreement, or similar data-handling arrangement under applicable law, the parties may enter into a separate agreement before such processing begins. Unless such separate agreement is in place, Sola Studio does not assume that the engagement is structured to receive or process Client customer data, production data, sensitive data, regulated data, or similar data on behalf of the Client.

5. The Client is responsible for revoking or reducing repository, staging-environment, account, credential, and other access when such access is no longer required for the engagement. Sola Studio will cease using such access when it is no longer reasonably necessary for the services and will delete credentials retained by Sola Studio within a reasonable period, subject to any different security procedure agreed by the parties.

6. Following completion or termination of an engagement, Sola Studio will, within a reasonable period, delete or return Client-provided data, source-code copies, materials, credentials, screenshots, recordings, and similar items that are no longer reasonably necessary, subject to applicable law, an applicable NDA or data-processing agreement, agreed retention conditions, ordinary backup cycles, and reasonable retention of contract, accounting, security, professional, or dispute-related records.

7. The Client is responsible for retaining its own copies of materials and work output required for its business, technical, legal, or recordkeeping purposes. Unless expressly agreed otherwise, Sola Studio does not provide long-term archival storage or backup services for Client materials or Shared Work Output.

8. Any information retained under paragraph 6 remains subject to the applicable confidentiality and data-handling obligations for so long as it is retained.

Article 24. Intellectual Property

1. All rights in Sola Studio’s pre-existing materials, templates, frameworks, generalized methodologies, checklists, worksheets, know-how, reusable assets, common design systems, generic code, process assets, and other reusable materials (“Sola Studio Background Assets”) remain exclusively with Sola Studio.
2. As to proposals, review materials, design materials, research notes, explanatory documents, structured materials, and other documents or materials created or shared in connection with the services (“Documents and Materials”), the Client receives, upon full payment of the applicable fees, a non-exclusive, non-transferable, non-sublicensable right to use them only to the extent necessary for the Client’s internal use and for the relevant project or service context. No assignment of rights in such Documents and Materials occurs unless expressly stated otherwise.
3. As to code, configuration, screen implementation, project-specific work outputs, and other outputs created for and embedded into the relevant project environment, the Client may, upon full payment of the applicable fees, use, copy, modify, and otherwise act upon them to the extent necessary for performance, operation, maintenance, and modification of that project, excluding any Sola Studio Background Assets and any generally reusable elements.
4. Except as expressly permitted above, the Client may not, without prior written consent from Sola Studio, resell, redistribute, generalize, template, commercially reuse, roll out across corporate groups, or repurpose for other projects any Sola Studio Background Assets or the outputs described above, except to the extent necessary for the relevant project’s implementation, maintenance, operation, or use by directly involved contractors in the Client’s internal project context.
5. Where the contracting Client is acting in connection with an identified end client, the Client may share Documents and Materials and other agreed project-specific outputs with that end client and directly involved project participants, and may permit them to use those items to the same extent reasonably necessary for implementation, operation, maintenance, review, or decision-making for the relevant project. This permission does not permit resale, general redistribution, use for an unrelated project, extraction or reuse of Sola Studio Background Assets, or broader commercialization unless expressly agreed otherwise. The Client remains responsible for ensuring that each recipient complies with the applicable confidentiality, use-scope, third-party-license, and other restrictions.
6. If any open-source software, third-party software, third-party libraries, third-party frameworks, or other third-party materials are included, those items remain subject to the applicable third-party license terms.
7. Any usage rights granted under this Article arise only after full payment of the applicable fees.
8. Any assignment of intellectual property, broader license, copyright transfer, work-made-for-hire treatment, or similar exception must be expressly stated in the relevant individual contract, SOW / Order Form, or Service-Specific Conditions.

Article 25. Publicity, Case Studies, and Portfolio Use

1. Sola Studio may publicly refer to the engagement, project summary, summary of support provided, case studies, portfolio information, images, excerpts from shared outputs, or related information only to the extent expressly permitted by the Client.
2. Even where permission is given, Sola Studio shall comply with the permitted scope, anonymization conditions, prior-review requirements, and any other conditions expressly specified by the Client.
3. If the Client has stated that publication is not permitted, or is permitted only on a conditional basis, Sola Studio will follow that designation.

Article 26. Subcontracting, Specialists, AI, and Third-Party Tools

1. Sola Studio may subcontract all or part of the services, or use specialists, professional advisors, external collaborators, or similar third parties, under its own responsibility.
2. Where confidential information is shared with such parties, Sola Studio shall ensure that they are subject to confidentiality obligations equivalent to or stronger than those in these Terms or any applicable NDA.
3. Access by a subcontractor, specialist, or external collaborator to confidential source code, repositories, non-public environments, credentials, or similar materials remains subject to any applicable NDA, Individual Agreement Documents, agreed access controls, and other information-handling conditions. Where a third party processes personal data on behalf of Sola Studio, Article 23(4), any applicable data-processing agreement, and applicable law govern the use of that third party.
4. Sola Studio may, at its discretion, use artificial intelligence systems, automated tools, development tools, analysis tools, and other third-party services as part of its ordinary working methods for evaluating, preparing, performing, reviewing, documenting, or otherwise supporting the services. Such use may include processing work-related information to the extent reasonably necessary for the relevant engagement, subject to applicable confidentiality obligations, data-handling conditions, any applicable NDA or data-processing agreement, and the provider terms or settings that Sola Studio reasonably considers appropriate for professional use.
5. Nothing in these Terms requires Sola Studio to use any artificial intelligence system or particular tool, to disclose its internal prompts or detailed internal workflow, or to continue using a tool that Sola Studio considers unsuitable, unavailable, insecure, inefficient, or otherwise inappropriate for the engagement.
6. Any Client request to prohibit or materially restrict the use of artificial intelligence or other tools is subject to Sola Studio’s prior express agreement and may affect acceptance, scope, fees, schedule, work method, available outputs, or other service conditions. Sola Studio may decline such a request or the related engagement where the requested restriction is not operationally reasonable.
7. If the Client requests the use of a particular artificial intelligence system, software, platform, model, account, environment, or other tool, such use remains subject to Sola Studio’s prior acceptance, access, security assessment, technical suitability, and operational feasibility. Unless expressly agreed otherwise, any additional license fees, subscription fees, usage charges, setup costs, integration costs, administration costs, or similar costs arising from the Client’s request shall be borne by the Client.

Article 27. Disclaimer of Warranties

1. Unless expressly stated otherwise, all services, shared outputs, reviews, advice, comments, materials, and structured outputs are provided on an as-is basis.

2. Sola Studio disclaims any implied warranties, including merchantability, fitness for a particular purpose, non-infringement, continued availability, and uninterrupted operation.

3. The Client remains solely responsible for its own final business decisions, internal decisions, legal decisions, regulatory decisions, implementation decisions, operational decisions, procurement decisions, and similar judgments made in reliance on the services.

4. Even where the services touch on privacy, cookies, consent management, accessibility, compliance, or other legal/regulatory matters, Sola Studio’s input is, unless expressly stated otherwise, practical or service-oriented guidance and does not constitute legal advice from a lawyer or other licensed legal professional. Final legal, regulatory, compliance, and external-responsibility determinations remain with the Client and/or its legal or other professional advisors.

5. Unless expressly stated otherwise, any comments, proposals, UX or messaging notes, review findings, wireframes, copy proposals, wording suggestions, localization-related input, or similar Shared Work Output relating to pages, flows, forms, messages, customer-facing digital touchpoints, marketing or sales materials, legal or policy page placement, disclosures, claims, pricing explanations, support information, or other client-facing materials do not constitute confirmation that such materials are legally compliant, regulatorily compliant, advertising-approved, tax-compliant, enforceable, complete, accurate, or suitable for publication in any particular jurisdiction or industry.

Article 28. Limitation of Liability

1. If either party breaches these Terms, any Service-Specific Conditions, or an applicable contract and causes damage to the other party, the liable party shall be responsible only for ordinary and direct damages actually incurred by the other party.
2. Sola Studio shall not be liable for lost profits, indirect damages, special damages, consequential damages, loss of opportunity, revenue loss, loss of goodwill, data loss, or similar damages.
3. The aggregate liability of Sola Studio shall not exceed:
   1. for Report-Type Services, the fees actually received by Sola Studio for the relevant service giving rise to the claim;
   2. for Consulting-Type Services, the fees actually received by Sola Studio for the relevant service giving rise to the claim;
   3. for Scoped Services, the fees actually received by Sola Studio for the relevant individual contract, SOW, service-specific conditions, or relevant scoped portion of the engagement directly related to the event giving rise to the claim; and
   4. for Ongoing Support Services, one month of fees actually received by Sola Studio corresponding to the month in which the event giving rise to the claim occurred.
4. The foregoing limitations do not apply where liability cannot be limited under applicable law or where damage is caused by Sola Studio’s willful misconduct or gross negligence.

Article 29. Termination

1. Either party may terminate the relevant contract or engagement if the other party breaches these Terms, the individual contract, the SOW / Order Form, or other applicable conditions and fails to cure such breach within a reasonable period after notice.
2. Sola Studio may, without prior notice, terminate the relevant contract or engagement, or suspend the services, if the Client:
   1. suspends payment or becomes unable to pay;
   2. becomes subject to bankruptcy, civil rehabilitation, corporate reorganization, liquidation, or similar proceedings;
   3. experiences a material deterioration in creditworthiness; or
   4. has any involvement with anti-social forces or other circumstances that Sola Studio reasonably considers materially problematic;
   5. is subject to, or is reasonably suspected by Sola Studio of being connected with, sanctions, export-control restrictions, anti-money laundering concerns, restricted transactions, restricted jurisdictions, or other legal or regulatory restrictions; or
   6. uses or attempts to use the services in connection with any activity, data, product, sector, country, person, entity, transaction, or project that Sola Studio reasonably considers legally, regulatorily, operationally, or reputationally unsuitable.
3. If, due to the Client’s requests, communication style, repeated instruction changes, refusal to cooperate, repeated scope overreach, explanation demands that to a reasonable degree obstruct ordinary performance of the services, harassment, serious information-management concerns, or similar circumstances, Sola Studio reasonably determines that continuation of the contractual relationship has become difficult, Sola Studio may, after requesting consultation or cure within a reasonable period, end the relevant contract or engagement.
4. Unless caused by Sola Studio’s willful misconduct or gross negligence, Sola Studio shall not be liable for damages suffered by the Client as a result of termination or suspension under this Article.
5. Settlement upon termination or ending of an engagement shall be governed by Article 21 and any applicable Service-Specific Conditions.

Article 30. Exclusion of Anti-Social Forces

1. The Client represents and warrants that it is not, and will not become, associated with any anti-social forces.
2. If Sola Studio reasonably determines that the Client has breached the preceding paragraph, Sola Studio may immediately terminate the contract without notice.

Article 31. Assignment Restriction

The Client may not assign, transfer, create security over, or otherwise dispose of its contractual position or any rights or obligations under these Terms or any individual contract without prior written consent from Sola Studio, except where Sola Studio reasonably agrees in connection with a merger, corporate split, business transfer, or similar succession transaction.

Article 32. Entire Agreement and Contract Changes

1. These Terms together with the applicable Service-Specific Conditions constitute the agreement between the parties regarding the relevant engagement and supersede prior oral or written exchanges on the same subject matter.
2. Any change to these Terms or to any Service-Specific Conditions is valid only if made in writing, in an electronically signed document, by approval email from an authorized person, or by another reliable electronic method.

Article 33. Changes to These Terms

1. Sola Studio may revise these Terms where required due to legal changes, service changes, operational needs, or other reasonable circumstances.
2. If Sola Studio revises these Terms, the revised content and effective date will be notified by publication on our website or by another appropriate method.
3. The revised Terms take effect on the effective date stated in such notice.
4. For Individual Agreement Documents already in force, the revised Terms may apply only to a reasonable extent, except where the Individual Agreement Documents provide otherwise or where the revision would materially affect important commercial conditions; in such cases, the parties may discuss the matter separately if necessary.

Article 34. Survival

Articles 12, 13, 15, 16, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 32, 33, 35, and 36, together with any other provisions that by their nature should survive, shall remain in effect after termination or expiration of the relevant contract.

Article 35. Governing Law and Jurisdiction

1. These Terms, any individual contract, any SOW / Order Form, any Service-Specific Conditions, and all matters arising in connection with them shall be governed by the laws of Japan.
2. Unless otherwise expressly agreed in a separate written document, the Tokyo District Court or Tokyo Summary Court shall have exclusive jurisdiction as the court of first instance over any dispute arising out of or in connection with these Terms.
3. If a separate written agreement expressly states different governing law or jurisdiction, that separate written agreement will prevail to that extent.

Article 36. Language

1. These Terms are provided in both Japanese and English. Both versions carry equal authority, and neither is treated as the original or standard version.
2. In the event of any inconsistency between the Japanese and English versions, the parties shall seek a consistent interpretation in good faith. Where a consistent interpretation cannot reasonably be reached, the matter may be addressed by mutual discussion between the parties.

---

The service-specific addenda below apply only to the specific services identified in each addendum.

Addendum for Accessibility Remediation Service

This Addendum applies to the Accessibility Remediation Service provided by Sola Studio. The Accessibility Remediation Service consists of the two independent services identified below. Matters not specified in this Addendum are governed by the Business Terms of Service (the “Terms”), and to the extent of any inconsistency between this Addendum and the Terms, this Addendum prevails solely with respect to the applicable Accessibility Remediation Service engagement.

Article 1. Service Structure and Eligible Engagements

1. The Accessibility Remediation Service consists of:
   1. Accessibility Scoping Confirmation, an individually quoted Report-Type Service; and
   2. Accessibility Remediation, a separately contracted Scoped Service.
2. The two services have separate fees, contract formation, payment, and service conditions. Payment for Accessibility Scoping Confirmation is not credited toward Accessibility Remediation unless Sola Studio expressly states otherwise.
3. Accessibility Scoping Confirmation is a mandatory preceding service for Accessibility Remediation. Accessibility Remediation is not provided without Accessibility Scoping Confirmation, even where the Client considers the existing findings, codebase, or access conditions sufficiently clear.
4. The Accessibility Remediation Service is offered as an international business service, with EU/UK-facing engagements as its primary standard focus. An engagement relating to another country or region is not automatically rejected solely because of that market, but remains subject to project fit, applicable standards, language, legal context, operational feasibility, payment conditions, contracting conditions, and other relevant circumstances.
5. The contracting Client may be an external audit or review provider, production company, or other partner engaging Sola Studio in connection with its end client, or may be the end client introduced by such a partner. The applicable contracting structure, invoicing relationship, information-sharing route, and responsibilities will be identified in the relevant Individual Agreement Documents.

Article 2. Required External Audit or Review Results

1. The Accessibility Remediation Service requires accessibility audit or review results prepared by an audit, review, or other review provider external to Sola Studio (the “External Findings”).
2. Automated-check results, an issue list prepared only by the Client, an internal issue list, an issue identified only by the Client’s engineer, an individual user report, or a reproducible issue without External Findings are not, by themselves, sufficient to enter Accessibility Scoping Confirmation or Accessibility Remediation.
3. Sola Studio does not provide an Accessibility Review service as part of the Accessibility Remediation Service and does not undertake to discover, audit, or organize missing accessibility issues for the purpose of creating External Findings.
4. If the External Findings are incomplete, unclear, outdated, or otherwise insufficient to support implementation estimation, Sola Studio may require the Client to obtain an additional or updated external audit or review before the engagement proceeds.
5. For service-eligibility purposes, Sola Studio may reasonably assess whether the External Findings contain sufficient structure, identification of the relevant scope or target items, issue descriptions, testing context, and supporting information to be used as input for Accessibility Scoping Confirmation. This intake assessment does not constitute validation of the accuracy, completeness, methodology, professional qualifications, or conclusions of the External Findings.

Article 3. Nature of Accessibility Scoping Confirmation

1. Accessibility Scoping Confirmation is an individually quoted Report-Type Service under which Sola Studio examines the External Findings in relation to the agreed codebase, staging environment, relevant flows, relevant components, dependencies, and other agreed materials for the purpose of preparing an implementation estimate for possible Accessibility Remediation.
2. Accessibility Scoping Confirmation may include review at DOM level or code level, identification of relevant implementation areas and implementation units, estimation of implementation effort, identification of constraints, dependencies, and assumptions, and identification of matters requiring Client confirmation or additional information.
3. Accessibility Scoping Confirmation does not include code changes, implementation, creation of a pull request, remediation work, a new accessibility audit or review, re-evaluation or verification of the accuracy or completeness of the External Findings, discovery or organization of missing accessibility issues, certification, conformance determination, or a guarantee that every External Finding is implementable or can be conclusively assessed.
4. The fee for Accessibility Scoping Confirmation is consideration for the review and estimation work itself, whether or not the Client later requests Accessibility Remediation.

Article 4. Pricing, Contract Formation, and Commencement of Accessibility Scoping Confirmation

1. The fee for Accessibility Scoping Confirmation is individually determined based on light intake information provided through the designated inquiry or application process and a limited pre-contract review of the External Findings, including their reported quantity, form, and granularity, anticipated codebase complexity, number of relevant flows or components, access conditions, and other relevant information.
2. After being presented with and accepting these Terms and the Privacy Policy through the designated inquiry process, the Client may share the External Findings before a separate NDA is executed by either:
   1. submitting an access-controlled file-sharing link through the designated inquiry form; or
   2. sending an access-controlled file-sharing link to info@solastudio.studio by email after submitting the form.
3. For purposes of Article 15(3) of the Terms, Sola Studio expressly agrees to receive External Findings shared in accordance with paragraph 2 as confidential information. Article 16 applies to those External Findings from the time they are received, whether or not a paid service contract is later formed or a separate NDA is executed.
4. The Client must have authority to share the External Findings with Sola Studio and should exclude personal information, credentials, and other sensitive information not reasonably necessary for the limited pre-contract review. This pre-NDA exception does not extend to source code, repository access, non-public staging or test-environment access, credentials, customer or user data, or other detailed confidential or sensitive materials unless Sola Studio expressly agrees otherwise.
5. The pre-contract review is limited to determining whether the External Findings were prepared by a provider external to Sola Studio, whether the subject matter appears to fit the standard service area, whether the form, quantity, granularity, structure, scope identification, issue descriptions, testing context, and supporting information are sufficient for intake purposes, and the amount of work reasonably relevant to pricing Accessibility Scoping Confirmation.
6. The pre-contract review does not include the detailed reading of External Findings required for implementation estimation, code review, identification of implementation areas or implementation units, estimation of implementation effort, identification of constraints, dependencies, or assumptions, implementation-method decisions, or preparation of a Remediation Estimate. Those activities form part of the paid Accessibility Scoping Confirmation service. Verification of the accuracy or completeness of the External Findings and discovery or organization of missing accessibility issues are not included in either the pre-contract review or Accessibility Scoping Confirmation.
7. Sharing External Findings or conducting the pre-contract review does not by itself form a contract for Accessibility Scoping Confirmation or require Sola Studio to accept or provide any paid service. Sola Studio may decline the inquiry after the pre-contract review.
8. A contract for Accessibility Scoping Confirmation is formed when the Client completes the payment specified by Sola Studio, unless the applicable Service-Specific Conditions expressly state otherwise.
9. The standard sequence is submission of the inquiry and External Findings, limited pre-contract review, acceptance or rejection of the inquiry, pricing of Accessibility Scoping Confirmation, payment, execution of an NDA, sharing of required codebase or environment access, and commencement of Accessibility Scoping Confirmation.
10. Sola Studio may defer commencement until payment, the NDA, sufficient External Findings, required access, identification of the relevant flows or components, and any other stated prerequisites are in place.
11. If the Client cancels Accessibility Scoping Confirmation after payment but before substantive review or estimation work begins, Sola Studio will refund the remaining prepaid amount after deducting non-refundable payment-processing, remittance, foreign-exchange, platform, or other third-party costs and reasonable costs of work, preparation, administration, or committed capacity already incurred.
12. If the Client cancels, pauses, reduces, or ends Accessibility Scoping Confirmation after substantive review or estimation work has begun, settlement is governed by Article 21 of the Terms. Any refund will be limited to the portion, if any, remaining after reasonable deduction for work performed or prepared, committed capacity, and incurred or non-cancelable costs.
13. If, for reasons attributable to Sola Studio, Sola Studio is unable to provide all or part of Accessibility Scoping Confirmation, Sola Studio will refund the amount reasonably corresponding to the unprovided portion, after excluding any portion already provided and subject to Article 21(15) of the Terms.

Article 5. Accessibility Scoping Confirmation Estimate

1. Based on the information and materials made available and reviewable at the relevant time, Sola Studio will prepare and share an implementation estimate in Google Sheets for the portions of possible Accessibility Remediation that can reasonably be estimated at that time (the “Remediation Estimate”).
2. The Remediation Estimate may identify:
   1. the External Findings, codebase, environments, flows, components, and other target items reviewed for estimation purposes;
   2. the identifiers or names of the relevant External Findings;
   3. the proposed Accessibility Remediation scope, including items identified as included, excluded, requiring confirmation, or not priced;
   4. the relevant implementation areas or components;
   5. a brief estimate basis sufficient to explain the proposed implementation work and estimated effort;
   6. estimated implementation effort;
   7. assumptions, dependencies, Client decisions, and other conditions relevant to the estimate;
   8. items that cannot be priced at that time and the reasons; and
   9. the estimated Accessibility Remediation fee and expected working period.
3. Related External Findings may be grouped into a common implementation unit where they concern the same component or implementation change. Sola Studio is not required to provide a separate explanation, difficulty rating, effort estimate, or fee breakdown for every External Finding.
4. The Remediation Estimate is prepared for estimation purposes. It does not constitute a new accessibility audit or review, re-evaluation or verification of the External Findings, detailed implementation specifications, implementation instructions, code examples, or remediation code.
5. The Remediation Estimate does not guarantee that every listed External Finding is implementable, that every listed External Finding will be included in Accessibility Remediation, or that the assumptions or conditions recorded at the time of estimation will remain unchanged. It does not constitute certification or a conformance determination and does not by itself constitute a binding offer, an Accessibility Remediation contract, or an obligation for Sola Studio to perform Accessibility Remediation. The Accessibility Remediation fee and expected working period agreed for a later engagement may differ from the Remediation Estimate as a result of the Client-selected scope, implementation dependencies, items requiring additional confirmation, changed assumptions, or other circumstances handled under this Addendum.
6. If an item cannot reasonably be priced without additional assumptions, Client decisions, materials, or confirmation, Sola Studio may identify that item as “Confirmation required,” “Not priced,” or an equivalent status and may omit a price for that item at the Accessibility Scoping Confirmation stage.
7. Sharing the Remediation Estimate marks the end of the service provision under Accessibility Scoping Confirmation. Article 20 nevertheless applies to clarification and Minor Revisions during the applicable Review Period and does not extend the scope of Accessibility Scoping Confirmation or postpone the end of service provision. New materials, changed assumptions, additional investigation, additional confirmation, additional estimation, or re-estimation are not Minor Revisions.
8. The Client is not required to request Accessibility Remediation after receiving the Remediation Estimate. Fees paid for Accessibility Scoping Confirmation are non-refundable merely because the Client does not proceed to Accessibility Remediation.

Article 6. Validity and Reconfirmation of the Remediation Estimate

1. The Remediation Estimate is valid for one (1) month from the date it is shared, provided that the target scope, External Findings, codebase, environment, dependencies, and other estimation assumptions remain unchanged.
2. If any estimation assumption changes, reconfirmation may be required even within the one-month period. Reconfirmation is also required after the one-month period has elapsed.
3. If the necessary reconfirmation involves material additional review or estimation work, Sola Studio may require a new Accessibility Scoping Confirmation engagement.
4. If the necessary confirmation and estimation work is minor, and the Client’s intention to proceed with Accessibility Remediation is substantially confirmed, Sola Studio may handle that confirmation before Accessibility Remediation begins and reflect the result in the Accessibility Remediation fee agreed for that engagement.
5. Sola Studio will determine whether the necessary reconfirmation is minor or requires a new Accessibility Scoping Confirmation engagement, taking into account the amount and nature of the required work.

Article 7. Contract Formation and Commencement of Accessibility Remediation

1. Accessibility Remediation is a separate Scoped Service. The end of service provision under Accessibility Scoping Confirmation or receipt of a Remediation Estimate does not create an Accessibility Remediation contract and does not oblige either party to enter into one.
2. Before Accessibility Remediation begins, the parties must confirm the External Findings or implementation units the Client wishes to address, the treatment of items identified as requiring confirmation or not priced, the agreed scope and excluded items, assumptions, dependencies, work method, repository or branch process, verification conditions, Client-side decision-makers, sharing method, fees, expected working period, payment conditions, and other necessary terms.
3. A contract for Accessibility Remediation is formed only when the parties enter into the applicable Individual Agreement Documents in accordance with Article 7(4) of the Terms.
4. Sola Studio may defer commencement until the applicable contract, payment, access, materials, repository or branch arrangements, staging or test environment, Client-side confirmation structure, any NDA or other information-handling arrangement required for the engagement, and other stated prerequisites are in place.
5. Where a separate NDA is used, the parties will confirm before Accessibility Remediation begins that the NDA or another applicable confidentiality arrangement covers the Accessibility Remediation work and the relevant information-sharing period. The parties may use an NDA that also covers inquiry evaluation, Accessibility Scoping Confirmation, Accessibility Remediation, and related follow-up work, unless the applicable NDA or Individual Agreement Documents provide otherwise.
6. The standard Accessibility Remediation engagement is not structured to receive or process production customer or user data, support messages containing personal data, sensitive personal information, regulated data, or similar data. The Client should provide test, synthetic, anonymized, or otherwise appropriately minimized data and least-privilege access where reasonably possible.
7. If data described in paragraph 6 is necessary for the agreed work, the parties must expressly agree on the need and applicable handling conditions before access or processing begins. Sola Studio may require an NDA, data-processing agreement, transfer arrangement, access controls, additional fees, revised scope, or other conditions, and may decline or defer the relevant work if appropriate conditions are not in place.

Article 8. Scope of Accessibility Remediation

1. Accessibility Remediation consists of frontend implementation work for the External Findings or implementation units and target pages, forms, user flows, screens, components, or code areas expressly included in the agreed scope.
2. Depending on the agreed scope, the service may include implementation relating to semantic HTML, form labels and descriptions, validation and error messages, focus visibility and management, keyboard operation, button and link semantics, ARIA use, accessible names, heading structure, modal or dialog behavior, selection controls, navigation behavior, visual states, reduced motion, skip links, and other agreed frontend accessibility matters.
3. Sola Studio may proceed without additional confirmation where a technical implementation correction is clear, remains within the agreed scope, and does not materially change product meaning, design direction, user flow, business rules, legal position, pricing, payment flow, or other Client-controlled decisions.
4. Client confirmation is required where a proposed change may affect content meaning, visual hierarchy, layout, product specifications, business logic, legal or compliance statements, brand expression, pricing, payment flow, third-party integration behavior, broad component architecture, or another Client-controlled decision.
5. Accessibility Remediation does not include review or remediation of any issue, page, flow, state, component, code area, platform, or environment not expressly included in the agreed scope.

Article 9. Scope Changes, Unpriced Items, and Additional Fees

1. An item identified in the Remediation Estimate as requiring confirmation, not priced, or an equivalent status is not automatically included in the Accessibility Remediation scope or fee.
2. Where confirmation and estimation of such an item are minor and are handled before Accessibility Remediation begins under Article 6(4), the resulting amount may be reflected in the Accessibility Remediation fee stated in the applicable Individual Agreement Documents.
3. Constraints, dependencies, additional issues, or other facts may first become apparent during implementation. If they require work outside the agreed scope or assumptions, Sola Studio may propose an additional estimate, a separate scope, revised conditions, or another reasonable arrangement.
4. A newly discovered issue is not automatically included in the agreed scope. Sola Studio may record or identify it without undertaking to remediate it.
5. Minor related work that is unavoidable for addressing an agreed issue may be handled within the original scope where Sola Studio reasonably determines it to be minor. Work affecting another page, flow, component, major refactor, design decision, product decision, verification range, or third-party integration is not treated as minor merely because it relates to an agreed issue.

Article 10. Work Output, Review Period, and Optional Final Meeting

1. Depending on the applicable Individual Agreement Documents, work output may be shared through a pull request, branch, patch, commit, repository, implementation notes, remediation summary, or another agreed method.
2. For purposes of Article 20 of the Terms, the Review Period begins when Sola Studio shares the post-work codebase through the agreed method. Where the agreed method is a pull request, branch, patch, commit, or repository access, making the relevant post-work code reasonably available to the Client constitutes that sharing step.
3. The default Review Period and Minor Revision rules in Article 20 apply unless the applicable Individual Agreement Documents expressly state otherwise. For clarity, the current default Review Period under Article 20 is five (5) calendar days, and responses qualifying as Minor Revisions are in principle limited to one round.
4. A final sharing meeting is not mandatory. It may be held if requested by the Client and accepted by Sola Studio. Whether or when such a meeting occurs does not delay the start of the Review Period.
5. During the Review Period, the Client may specifically notify Sola Studio of clarification questions, obvious written errors in shared notes, or an alleged implementation deficiency concerning the same agreed issue under the agreed verification conditions. New issues, new pages or flows, new materials, specification changes, design changes, additional pull requests, deployment work, production support, formal audit requests, legal-compliance questions, or out-of-scope quality assurance are not included.

Article 11. Verification and Limitations

1. Post-implementation verification is limited to the agreed issues, target items, verification methods, environments, browsers, states, and other agreed conditions. It is not a full re-audit.
2. A statement that an issue was addressed or checked means only that the agreed implementation response was performed and the same failure was not observed under the agreed verification conditions.
3. Accessibility Remediation does not include or guarantee, unless expressly agreed otherwise:
   1. legal or regulatory compliance;
   2. EAA compliance or legal determination;
   3. EN 301 549 full conformance assessment;
   4. WCAG conformance certification or full conformance audit;
   5. public-sector compliance or procurement-ready evidence;
   6. certification, accreditation, VPAT, or ACR;
   7. full-site or all-issues remediation;
   8. verification across all browsers, devices, assistive technologies, states, or environments;
   9. full screen-reader matrix testing, including NVDA or JAWS testing, unless separately agreed;
   10. testing with people with disabilities;
   11. native-mobile-app, PDF, or document accessibility remediation;
   12. remediation of third-party tools or widgets beyond the Client’s practical control;
   13. broad redesign, design-system-wide refactoring, backend, API, database, or infrastructure work unless separately agreed;
   14. merge, deployment, release, production behavior, or production incident response;
   15. long-term maintenance, continuous monitoring, or preservation of accessibility after future changes; or
   16. preparation or confirmation of the Client’s legal, compliance, conformance, certification, or accessibility statement.
4. Sola Studio does not guarantee that all External Findings can be remediated, that no additional accessibility issue exists, or that an external reviewer, authority, procurement body, or other third party will accept or approve the work.

Article 12. Relationship with External Review and Follow-Up Work

1. Any additional audit, re-audit, external verification, certification review, or review of a new or changed scope must be obtained separately from an external provider and is not included in Accessibility Remediation.
2. Additional findings, pages, flows, components, continued implementation support, or other follow-up work may be proposed under a separate estimate, separate Scoped Service, or other separately agreed service where available.
3. No suggestion of follow-up work creates an obligation for the Client to request it or for Sola Studio to accept it.

Addendum for Conversion Leak Estimator

This Addendum applies to the Conversion Leak Estimator provided by Sola Studio (the “Estimator”). Matters not specified in this Addendum will be governed by the Business Terms of Service (the “Terms”), and, to the extent of any inconsistency between this Addendum and the Terms, this Addendum will prevail solely with respect to the Estimator.

Article 1. Nature and Purpose of the Estimator

1. The Estimator is a free tool intended to help visualize possible opportunity loss arising from friction on a page, form, or conversion flow, including user hesitation, drop-off, misunderstanding, and similar points of friction, based on information entered by the user and calculation assumptions adopted by Sola Studio.

2. The Estimator provides reference information only. It does not inspect or analyze the user’s actual website, product, screen, form, flow, implementation, analytics, or operational conditions.

3. Use of the Estimator does not create a contract for any paid review, implementation, consultation, or other paid service.

4. If a user wishes to use a paid service after using the Estimator, the user must separately complete the inquiry, application, agreement, payment, submission of information, or other procedure specified for that service.

Article 2. Nature of Estimates and Outputs

1. Any figures, ranges, estimated amounts, opportunity-loss indications, or similar outputs displayed by the Estimator are rough estimates based on information entered by the user and the calculation assumptions adopted by Sola Studio.

2. Such outputs do not represent or guarantee actual loss amounts, recoverable amounts, revenue increases, CVR improvement, increased inquiries, increased registrations, increased purchases, improved form-completion rates, improved conversion-to-opportunity rates, improved win rates, or any other specific outcome or result.

3. The user remains responsible for determining whether the information entered into the Estimator is accurate, complete, current, and appropriate for the intended calculation.

4. The user shall use the Estimator’s outputs at its own responsibility as reference material for business judgment, internal explanation, investment decisions, implementation decisions, or similar evaluation. Sola Studio will not be responsible for decisions made by the user or any third party based solely on those outputs.

5. The Estimator’s outputs do not identify, diagnose, or provide implementation directions regarding any specific flow, screen, wording, information structure, implementation, analytics setup, or operational issue.

6. Concrete observation, review, analysis, improvement planning, implementation, or implementation support is not included in the Estimator and requires a separately agreed service where such support is available.

Article 3. Availability and Changes

1. Sola Studio may modify the Estimator’s calculation assumptions, inputs, presentation, features, or availability where reasonably necessary for maintenance, improvement, operational changes, or other appropriate reasons.

2. Unless expressly stated otherwise, Sola Studio does not guarantee that the Estimator will remain continuously available, error-free, or unchanged.
