Terms of Use

Effective date: October 9, 2026 · Version 1.2

Article 1 (Purpose and Scope)

These Terms set out the rights, obligations, and responsibilities between Promegas Interactive (the “Company”) and users when using the Company’s website, Book of Change app, I Ching interpretations, and related interactive digital services (collectively, the “Services”). If separate terms apply to a particular Service, those terms also apply to that Service.

Article 2 (Definitions)

1. “User” means a person who uses the Services under these Terms.
2. “Content” means digital materials provided through the Services, including apps, websites, text, interpretations, images, software, and AI-generated responses.
3. “User Submission” means content that a User enters or submits to the Services, including questions, consultation text, materials, or feedback.

Article 3 (Posting and Changes to these Terms)

1. The Company will post these Terms where users can review them on the Services or website.
2. The Company may amend these Terms to the extent permitted by applicable law. For changes that are material or adverse to users, the Company will generally announce the effective date and reasons at least 30 days in advance. Other changes will be announced within a reasonable period before they take effect.
3. A User who does not agree to amended Terms may stop using the Services and request account termination before or after the effective date. The Company will obtain separate consent when required by law. Continued use after an announcement does not replace consent required by mandatory law.

Article 4 (Services, Changes, and Temporary Suspension)

1. The Company provides company information, the Book of Change app, I Ching-related digital content, interactive features that process User Submissions, and related services.
2. The Company may change features or Content for security, technical or operational reasons, changes by external providers, legal compliance, or service improvement. The Company will give advance notice where practicable of changes or termination that materially affect users. Refunds to paid users will be handled under applicable law and purchase terms.
3. The Services may be delayed or suspended due to scheduled maintenance, outages, network or app marketplace issues, authentication or AI provider outages, natural disasters, or other events reasonably beyond the Company’s control. The Company will address the cause and provide recovery updates where reasonably possible.
4. The Company does not guarantee uninterrupted or error-free service or compatibility with every device or environment. This does not exclude statutory warranties or liability arising from the Company’s fault.

Article 5 (Accounts and User Responsibilities)

1. Features that require an account may be used after completing the authentication procedure provided by the Company. Users must use an email address or authentication method they are authorized to use.
2. Users must safeguard their accounts and authentication credentials and notify the Company if they become aware of unauthorized use. A User is responsible, to the extent attributable to the User, for loss caused by the User’s intentional or negligent failure to protect authentication information.
3. Requests to delete an account may be sent to contact@promegas.com. Information after account termination will be handled under the Privacy Policy and applicable legal retention requirements. Consultation history stored only on a device may need to be deleted separately in the app.

Article 6 (User Submissions and Prohibited Conduct)

1. Users must own or have lawful authority to submit User Submissions. Do not submit or share content that infringes another person’s privacy, copyright, reputation, or other rights.
2. Users grant the Company a non-exclusive, purpose-limited right to process User Submissions only as needed to provide, display, store, and technically transmit the Services. This right is limited to service delivery and does not authorize the Company to advertise with or sell User Submissions, or to use them to train the Company’s own AI model. Processing by an external AI provider is described in the Privacy Policy.
3. Users must not use the Services for unlawful conduct, impersonation, infringement, malware distribution, circumvention of security, excessive automated requests, unauthorized copying or distribution, or disruption of the Services.
4. If a claim is made that a User Submission infringes a third party’s rights, the Company may request that the material be made unavailable, removed, or restricted to the extent reasonably necessary. If a User’s intentional or negligent breach causes the Company direct loss, the User is responsible for damages attributable to that breach and having a reasonable causal connection, as provided by applicable law. This Article does not transfer or limit the Company’s liability for its own fault or any User’s statutory rights.

Article 7 (Intellectual Property)

1. Intellectual property rights in the Services and Content provided by the Company belong to the Company or the lawful rights holder. These Terms do not transfer ownership to Users.
2. The Company grants Users a limited, non-transferable right to use the Services for personal, non-commercial purposes. Except as permitted by law or authorized by the rights holder, Users may not copy, modify, sell, redistribute, or publicly transmit Content.
3. If a User believes that the Services or Content infringe rights, the User may report the rights holder, material, and supporting grounds to contact@promegas.com. The Company will review the report and take appropriate action.

Article 8 (AI Features and Limitations of Results)

1. AI interpretations in Book of Change are reference information generated from a User’s question and necessary consultation context. AI results may be inaccurate, incomplete, or unsuitable for a User’s circumstances. The Company does not guarantee any particular result, prediction, or effect.
2. AI interpretations and I Ching readings are for entertainment, information, and self-reflection. They are not a substitute for professional advice, diagnosis, or decision-making in areas such as medicine, law, investment, finance, or psychotherapy. Consult a suitably qualified professional for important decisions.
3. When using an AI feature, questions and consultation context needed to generate a response may be sent to an external AI provider. Users should not enter sensitive information, passwords, financial information, national identification numbers, or another person’s personal information. See the Privacy Policy for processing details and external provider terms.
4. This Article does not exclude liability arising from the Company’s intentional or negligent conduct, false or misleading statements, or violation of legal duties.

Article 9 (Paid Content, Payment, and Refunds)

1. If the Company sells paid features or Content, it will clearly disclose before purchase the content, price, payment provider and method, delivery time, and cancellation, withdrawal, and refund terms.
2. Payments through an app marketplace are subject to that marketplace’s purchase and cancellation procedures and applicable law. Any restriction on withdrawal after digital Content has begun to be supplied will apply only to the extent permitted by law and after required advance notices and consents.
3. Users may report service errors, duplicate charges, non-delivery, or Content that differs from its description. The Company will review the facts and respond under applicable law and purchase terms.

Article 10 (Restrictions and Termination)

1. If a User violates these Terms or applicable law, or creates a substantial risk to the security or rights of the Services, Users, or third parties, the Company may take the least restrictive measure reasonably necessary, including a warning, Content restriction, temporary suspension, or termination.
2. For urgent security or unlawful conduct, the Company may impose a restriction before notice. The Company will notify the User of the reason and how to object as soon as reasonably possible and will review the User’s explanation.
3. Users may stop using the Services and request account deletion at any time. If the Company terminates the Services, remaining rights and refunds for paid Users will be handled under applicable law.

Article 11 (Damages and Scope of Liability)

1. If the Company or a User causes loss to the other by intentionally or negligently violating applicable law or these Terms, the responsible party will compensate the loss to the extent attributable to that party and reasonably causally connected, as provided by applicable law.
2. The Company is liable for losses it causes to Users as required by law. To the extent permitted by law, liability may be limited for loss that occurs without fault by the Company or results from special circumstances that could not ordinarily have been foreseen.
3. These Terms do not exclude or limit liability or rights that cannot legally be limited, including the Company’s willful misconduct or gross negligence, death or personal injury, violation of personal information protection duties, or consumer rights under mandatory law.
4. The Company does not automatically disclaim liability for outages of external providers or problems with a User’s device or network if the Company failed to meet its reasonable duty of care.

Article 12 (Disputes and Governing Law)

The Company and Users will first make reasonable efforts to resolve disputes through good-faith discussion. If they cannot resolve a dispute, either party may refer it to consumer dispute mediation or a competent authority or court under applicable law. Governing law and venue will be determined under applicable law without restricting consumers’ statutory rights.
