Thylib Terms of Service

Version: 2026-06-26.1 Effective: 2026-06-26

1. Eligibility

The Thylib service is offered only to natural persons aged 18 or older who are residents of the United States. By using the service you represent that you meet these requirements.

2. The service

Thylib is a personal health-records platform. We help you import, organize, and explore your own medical records — conditions, lab results, vitals, medications, allergies, immunizations, procedures, reports, and visit history — from healthcare providers you connect (e.g. via Epic MyChart or other SMART-on-FHIR patient portals), and to query those records through the interfaces described in §7.

Thylib is not a healthcare provider, is not a clinical diagnostic service, and does not provide medical advice. Records shown in Thylib are copies synced from your providers and may be incomplete or out of date; your provider's chart remains the authoritative record. Nothing returned by the service should be acted on without consultation with a qualified healthcare provider.

3. Accounts and family access

You access Thylib by signing in with Google. One Google account = one Thylib user. A user may belong to one or more families, the unit of data ownership inside Thylib. Within a family, members hold either the admin role (manages connections and billing) or viewer role (read-only). Family admins are responsible for ensuring they have legal authority to connect and view any other person's records within the family (for example, as a parent or legal guardian of a minor, or with the documented permission of another adult).

4. Subscription; automatic renewal

Use of Thylib beyond the marketing pages requires an active subscription on your family. Please read this section carefully — your subscription renews automatically.

  • Price. The annual rate shown at checkout (plus applicable tax), billed via Stripe. One subscription covers the whole family; the family admin pays and viewers do not pay separately. Promotional or discounted rates may be granted at our discretion.
  • Term and renewal. The term is 1 year, billed in advance. Your subscription renews automatically each year on or about the anniversary of your purchase, and your payment method on file is charged the then-current rate, until you cancel.
  • Consent. At checkout you are shown these renewal terms and must affirmatively agree to them (a separate checkbox) before payment. We retain a record of your consent.
  • Renewal reminders. We email the family admin approximately 40 days before each renewal with the renewal date, the amount to be charged, and a one-click cancellation link.
  • How to cancel. Online, in one click, at any time: Billing → Cancel subscription, or the cancellation link in any billing email. Cancelling turns off auto-renewal; you keep access until the end of the paid year and are not charged again. No phone call is required.
  • Refunds. A full refund is available within 15 days of your first purchase. After that, you can cancel at any time for a prorated refund of the unused part of your paid year (or simply turn off auto-renewal and keep access through the end of the term). See the Refund Policy for details, including price-increase rights for New York residents.
  • Price changes. We will email you before any price increase takes effect, including your next renewal date and the new amount.
  • Lapse. If your subscription ends and is not renewed, your imported health-record data is retained for one year and then permanently deleted, as described in the Privacy Policy.

5. Acceptable use

You agree not to:

  • Connect or view another person's records without legal authority or their informed permission.
  • Share your account credentials.
  • Attempt to access data belonging to other Thylib users or families.
  • Use Thylib to deliver clinical services to third parties; Thylib is a consumer tool, not a medical device or an EHR for practices.
  • Reverse-engineer, scrape, or attempt to circumvent our security measures.

6. Your data; our role

Your health records remain yours. Thylib processes them on your behalf to provide the features described in the Privacy Policy. Thylib is a consumer service acting at your direction: we are not a HIPAA covered entity or business associate of your providers, and your use of Thylib is not part of your providers' HIPAA-covered treatment relationship with you. The consumer health-data protections that apply to Thylib are described in the Privacy Policy.

7. Third-party AI / LLM tool integration

Thylib supports an optional Model Context Protocol (MCP) integration that lets you query your own records from third-party AI assistants such as Claude, ChatGPT, or Gemini. When you use that feature, your data leaves the Thylib servers and is sent to the AI provider you have connected. This is described in detail in the AI/LLM Disclosure document, which you must accept separately before the feature is enabled.

8. Disclaimers

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. THYLIB MAKES NO WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT, AND NO WARRANTY THAT RECORDS SYNCED FROM YOUR PROVIDERS ARE COMPLETE, CURRENT, OR ERROR-FREE. NOTHING RETURNED BY THE SERVICE IS A DIAGNOSIS, PROGNOSIS, OR PRESCRIPTION.

9. Limitation of liability

To the maximum extent permitted by law, Thylib's aggregate liability is limited to the greater of (a) USD 100 or (b) the fees you paid Thylib in the twelve months preceding the event giving rise to the claim. Some jurisdictions do not allow certain limitations; in those jurisdictions this section applies to the fullest extent permitted.

10. Dispute resolution; governing law

These Terms are governed by the laws of the State of California. Disputes will be resolved by binding arbitration in California, except small-claims matters and equitable relief, and except where applicable law gives you a non-waivable right to bring an action in court.

11. Changes to these Terms

We may update these Terms. Material changes will be presented for your re-acceptance on next sign-in and announced by email at least 14 days before they take effect. Non-material changes (typo fixes, restructuring without substantive change) will be announced by email and reflected in the version string above; continued use of the service after the effective date constitutes acceptance of non-material updates.

12. Termination

You may terminate at any time by cancelling your subscription (§4) and/or deleting your account. We may terminate or suspend access for material violation of these Terms, with notice where reasonable. Data retention and destruction on termination are governed by the Privacy Policy.
