Terms of Service

1. What Xanadu Is (and Is Not)

By using the Xanadu application ("Service"), you agree to these Terms with Your Data Health, Inc. ("Xanadu," "we," "us"), a company operating in Washington State.

Xanadu is a Patient-Owned Data Trust: software that lets you aggregate, manage, and selectively license your own health data, with you retaining ownership and receiving 80% of any licensing revenue.

Xanadu is not a healthcare provider, HIPAA covered entity, medical device, diagnostic tool, or substitute for professional medical advice. Nothing in this Service constitutes medical advice. The Xanadu Score is a data quality index, not a clinical measurement. Always consult a licensed healthcare provider for medical decisions.

2. Eligibility

You must be at least 18 years old to use the Service. We do not knowingly provide Services to minors.

3. Your Account

• You are responsible for maintaining the security of your login credentials.
• You must provide accurate account information.
• Notify us immediately at privacy@yourdata.health if you believe your account is compromised.
• You may not create an account on behalf of another person without their explicit consent.

4. Health Data: Ownership and License

You own your data

Your health data belongs to you. These Terms do not transfer ownership of your health data to Xanadu.

Limited license to operate the Service

You grant Xanadu a limited, non-exclusive, non-transferable, revocable license to process your health data solely to provide the Service: to organize it on your device, keep it secure, compute your Xanadu Score™, and transmit only the data you explicitly choose to share under a research lease you activate. This license terminates when you delete your account or revoke consent.

5. Research Leases and Revenue Share

When you activate a research lease, you grant the named research organization a time-limited, revocable, non-exclusive license to use your de-identified FHIR data for the stated research purpose. Lease terms are shown before activation and require explicit acceptance.

Xanadu pays you 80% of gross revenue received from each lease attributed to your data. Xanadu retains 20% as a platform fee. Revenue share is a contractual obligation but not a guarantee of any particular income level.

You may revoke any lease at any time from the Kill Switch screen. Revocation terminates the research organization's license as of that date.

6. Acceptable Use

You may not:

• Submit false or fabricated health data to research organizations
• Attempt to re-identify de-identified data shared under a lease
• Interfere with the Service's technical operations or security
• Access another user's account or data
• Use the Service to violate any applicable law
• Copy, decompile, reverse-engineer, or attempt to extract the source code, models, or design of the Service, except where that restriction is prohibited by law
• Use the Service to misappropriate Xanadu's trade secrets or intellectual property

7. Intellectual Property

The Xanadu application and all associated software, designs, branding, and technology are owned by Your Data Health, Inc. and protected by copyright, trademark, patent, and trade secret law. Patent applications are on file. "Xanadu," "Xanadu Health," and "Xanadu Score" are trademarks of Your Data Health, Inc. These Terms grant you no rights to Xanadu's intellectual property beyond use of the Service. Your health data is yours; the technology for processing it is ours.

8. Privacy

Our Privacy Policy governs how we collect and use your information. It explains your rights under MHMDA, CCPA, GDPR, and other applicable laws, and is incorporated into these Terms by reference.

9. Termination

By you

Delete your account from within the app at any time. We will delete your data within 30 days. Revenue earned before termination is paid on the next scheduled date.

By us

We may suspend or terminate your account for violations of these Terms, fraud, or legal necessity. We will provide notice except in cases of fraud or legal emergency. All research leases terminate immediately upon account deletion.

10. Disclaimers

11. Limitation of Liability

12. Governing Law and Disputes

These Terms are governed by Washington State law. Disputes that cannot be resolved informally shall be submitted to binding arbitration in King County, Washington under AAA Consumer Arbitration Rules, except that either party may seek injunctive relief in court to protect IP or confidential information. You agree to resolve disputes individually, not as part of a class action. If the class action waiver is found unenforceable, the arbitration clause shall not apply to that claim.

We will provide 30 days' notice before material changes to these Terms.
