Terms of Service

1. The service

twyn.life ("twyn", "the service") is a personal health data platform operated by Oleksii Lazorenko. It aggregates, normalizes, and stores health data that you provide, and exposes that data back to you and to AI tools you choose to connect via the Model Context Protocol (MCP). The service is currently in private beta.

2. Not medical advice

twyn is a system of record, not a medical device and not a healthcare provider. It does not diagnose, treat, prescribe, or provide medical advice. Outputs of AI tools you connect to your data are not medical advice either. Always consult a qualified clinician before making health decisions. Do not use twyn for emergencies.

3. Your account

• You must be at least 18 years old to use the service.
• You are responsible for keeping your credentials and access tokens confidential.
• Access tokens you issue (MCP tokens, ingestion tokens) grant read or write access to your data. Treat them like passwords and revoke any token you no longer use.
• One account is for one person's data — your own, or that of someone who has authorized you.

4. Your data

Your data remains yours. By uploading it you grant us only the limited license needed to store, process, and display it back to you and to the agents you connect — nothing more. How we handle data is described in the Privacy Policy. You can request a full export or deletion at any time.

5. Acceptable use

• No attempts to access other users' data or probe the service's security.
• No use of the service to store unlawful content.
• No reselling or white-labeling the service without a written agreement.
• No abusive load (scraping, flooding ingestion endpoints beyond personal use).

6. Beta status, availability, and changes

The service is provided "as is", without warranties. During the beta there is no uptime guarantee, features may change or be removed, and although we take backups and care, you should not treat twyn as your only copy of critical medical documents. We may suspend accounts that violate these terms.

7. Fees

The private beta is free. We expect to introduce paid plans later; pricing and terms will be announced in advance, and no charges will ever be applied without your explicit sign-up for a paid plan.

8. Liability

To the maximum extent permitted by law, our total liability arising out of the service is limited to the amount you paid for it in the preceding 12 months (during the free beta: zero). We are not liable for indirect or consequential damages, or for decisions made based on data or AI outputs.

9. Termination

You may stop using the service and delete your account at any time. We may terminate accounts that violate these terms, with notice where practicable. Upon deletion, your data is removed as described in the Privacy Policy.

10. Governing law

These terms are governed by the laws of Portugal. Mandatory consumer-protection rules of your country of residence remain unaffected.
