These Terms apply to all users, including waitlist subscribers, free tier users, and paid subscribers.

• MCP Server: integration layer allowing AI agents (Cursor, Claude Code, etc.) to read and write Chain entries
• CLI: command-line interface for interacting with your workspace
• Web application: browser-based workspace for visual management of Chain entries
• Community: forums and learning resources at community.productbrain.io
• Waitlist: early access registration for upcoming features and availability

3. Account and Registration

To use certain features, you must create an account. You agree to:

• Provide accurate and complete registration information
• Keep your account credentials secure and confidential
• Notify us immediately of any unauthorized use of your account
• Accept responsibility for all activity under your account

You must be at least 16 years old to create an account or use the Service.

4. User Obligations

You agree to use the Service lawfully and responsibly. You must not:

• Violate any applicable laws or regulations
• Use the Service to store or transmit malicious code
• Attempt to gain unauthorized access to the Service or other users' data
• Interfere with or disrupt the Service's infrastructure

5. Your Content and Data

You own your data. All Chain entries, workspace content, and data you create within Product Brain remain your intellectual property. We do not claim any ownership rights over your content.

By using the Service, you grant us a limited license to store, process, and display your content solely for the purpose of providing the Service to you. This license terminates when you delete your content or close your account.

You are responsible for maintaining backups of your data. While we implement reasonable data protection measures, we recommend exporting your Chain data regularly.

6. AI-Specific Terms

Product Brain integrates with third-party AI services. The following terms apply:

No Training on Your Data

We do not use your workspace data, Chain entries, or any content you create to train AI models. Your data is used exclusively to provide the Service to you.

Third-Party AI Model Pass-Through

When you use features that involve AI processing (such as the MCP server with AI agents, Brain Chat, or CI code review), your content may be sent to third-party AI providers (such as OpenRouter, Anthropic, or OpenAI) for processing. For CI code review, this includes the pull-request title and body, the code diff, a bounded semantic representation used to find relevant workspace knowledge, and the selected Chain entries used by the review model. These transmissions are governed by the respective provider's terms and privacy policies. We select providers that commit to not training on customer data.

AI Output Ownership

Content generated by AI tools within your workspace (e.g., facilitated shaping sessions, suggested entries) is owned by you. We make no claim to AI-generated outputs created in your workspace.

Output Similarity

AI-generated outputs may be similar across different users due to the nature of large language models. Such similarity does not constitute infringement of any user's intellectual property. We do not guarantee that AI-generated content is unique.

Sensitive Data

Do not store highly sensitive personal data (health records, financial account numbers, government-issued identifiers) in Chain entries that will be processed by AI agents. While your workspace is isolated, AI processing involves third-party services. Use the Service for product management data, not as a repository for sensitive personal information.

7. Service Tiers and Payment

Product Brain offers multiple service tiers. The free tier is provided at no cost with no time limit. Paid tiers require a subscription. Pricing, features, and tier details are described on our Pricing page.

For paid subscriptions:

• Payment is due at the beginning of each billing period
• All fees are exclusive of applicable taxes
• We may change pricing with 30 days' advance notice
• You may cancel at any time; service continues until the end of the billing period
• Refunds are handled on a case-by-case basis

8. Intellectual Property

The Service, including its design, features, documentation, and underlying technology, is the intellectual property of YOUNG HUMAN S.L. The “Product Brain” name, logo, and associated marks are trademarks of YOUNG HUMAN S.L.

Certain components are available under open-source licenses, as indicated in their respective repositories. Open-source components are governed by their own license terms.

Nothing in these Terms grants you the right to use our trademarks, logos, or brand assets without prior written consent.

9. Limitation of Liability

To the maximum extent permitted by law:

• The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied
• We do not warrant that the Service will be uninterrupted, error-free, or secure
• We shall not be liable for any indirect, incidental, special, consequential, or punitive damages
• Our total aggregate liability for any claims arising from or related to the Service shall not exceed the amount you paid us in the 12 months preceding the claim

These limitations do not apply where prohibited by applicable law, including mandatory consumer protection provisions under Spanish and EU law.

10. Indemnification

You agree to indemnify and hold harmless YOUNG HUMAN S.L. from any claims, losses, damages, liabilities, and expenses (including legal fees) arising from your use of the Service, your violation of these Terms, or your violation of any rights of a third party.

11. Termination

You may terminate your account at any time by contacting us at [email protected] or through the account settings in the Service.

We may suspend or terminate your access if you violate these Terms, with notice where practicable. Upon termination:

• Your right to use the Service ceases immediately
• We will make your data available for export for 30 days
• After the export period, your data will be deleted (subject to legal retention requirements)

12. Governing Law and Dispute Resolution

These Terms are governed by the laws of Spain. Any disputes shall be submitted to the courts and tribunals of Las Palmas de Gran Canaria, except where mandatory consumer protection law provides otherwise.

For users qualifying as consumers under EU law, you retain the right to bring proceedings in your country of residence. Nothing in these Terms limits your rights under mandatory consumer protection legislation.

Before initiating legal proceedings, we encourage you to contact us to resolve disputes amicably. You may also use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr.

13. Changes to These Terms

We may modify these Terms at any time. Material changes will be communicated via email or a prominent notice on the Service at least 30 days before taking effect. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.

If you do not agree to the updated Terms, you may terminate your account before the changes take effect.

14. Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it enforceable while preserving its original intent.
