Summara Health

Terms of Service

Effective February 16, 2026 · Last updated February 16, 2026

1. Agreement to these Terms

Welcome to Summara Health ("Summara," "we," "us," or "our"), an AI-powered care-navigation and educational service operated by Thronos Holdings, LLC, a limited liability company organized under the laws of the State of Texas, USA. By creating an account, subscribing, or using the Summara Health mobile app or website (the "Service") you agree to these Terms of Service (the "Terms") and to our Privacy Policy and Medical Disclaimer, which are incorporated by reference. If you do not agree, do not use the Service.

2. Eligibility

You must be at least 18 years old and legally able to enter into a binding agreement in your jurisdiction to use Summara Health. By using the Service you represent that you meet these requirements.

3. The Service — what Summara is and is not

Summara Health provides consumer-facing tools that use artificial intelligence to translate medical text into plain English, summarize physician visits and paperwork, explain medications and lab/imaging results, answer follow-up questions, and organize your personal medical timeline.

Summara Health is not a medical provider. Summara is an educational and organizational tool. It is not a substitute for professional medical advice, diagnosis, or treatment. It is not a medical device, is not FDA-cleared, and does not deliver clinical decision-support. Always consult your physician or other qualified healthcare provider about your care. In an emergency call 911 or your local emergency number. See our Medical Disclaimer for details.

4. Your account

5. Subscriptions

Summara offers two paid plans, both auto-renewing subscriptions:

5.1 Billing and auto-renewal (both plans)

5.2 Household members (Elite Family)

An Elite Family subscription covers the subscriber plus up to four additional household members, each with their own private account. Nothing is shared between accounts unless a member chooses to share it. If the subscription lapses or a member is removed, that member's Elite entitlement ends but their account and records remain intact, operated by Thronos Holdings, LLC or its successor.

5.3 Refunds

All refunds are processed by Apple or Google in accordance with their respective store policies:

Summara Health does not accept refund requests directly and does not have the ability to issue refunds on the store's behalf.

5.4 Promotional periods

If we offer a promotional period, the terms of that offer will be disclosed at the time of purchase and are subject to these Terms. Unused trial time is forfeited if you subscribe to a paid plan or cancel early.

5.5 Price and feature changes

We may change the price of Pro or Elite prospectively. Existing Elite holders retain their current entitlement at the price they paid. Pro renewals at a new price will be disclosed in advance where required by the App Store or Google Play.

6. Acceptable use

You agree that you will not, and will not attempt to:

7. User content and license

You retain full ownership of the medical text, questions, and other content you submit to Summara ("User Content"). You grant us a worldwide, royalty-free, non-exclusive license to host, store, process, transmit, and transform your User Content solely to operate the Service for you — including sending it to our AI provider to generate summaries and answers, displaying it back to you, and preserving it in your personal medical timeline. This license terminates when you delete the content or your account (subject to reasonable backup retention windows described in our Privacy Policy).

We will not use your User Content to train AI models or share it with advertisers, and we will not disclose it to third parties except as described in the Privacy Policy.

8. AI outputs

Summara's summaries, translations, and answers are produced by large language models and can contain errors, omissions, or hallucinations. AI outputs are educational aids only, are provided "as is," and are not a substitute for qualified medical judgment. You are solely responsible for how you act on any AI output.

9. Intellectual property

The Service, including its software, user interface, brand, and content (other than User Content), is owned by Thronos Holdings, LLC and its licensors and is protected by copyright, trademark, and other intellectual property laws. You are granted a limited, personal, non-exclusive, non-transferable license to use the Service in accordance with these Terms; no other rights are granted.

The names "Summara," "Summara Health," and related logos are trademarks of Thronos Holdings, LLC. All other trademarks are the property of their owners.

10. Third-party services

The Service integrates with third-party services including Apple App Store, Google Play, and OpenAI. Your use of those services is subject to their own terms. We are not responsible for the acts or omissions of those third parties.

11. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR THE ABSENCE OF ERRORS. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, ACCURATE, OR ERROR-FREE. NOTHING IN THE SERVICE CONSTITUTES MEDICAL ADVICE.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL Thronos Holdings, LLC, ITS OFFICERS, EMPLOYEES, AGENTS, LICENSORS, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE OR RELIANCE ON ANY AI OUTPUT, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM AND (B) ONE HUNDRED U.S. DOLLARS ($100).

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above may not apply to you. Nothing in these Terms limits liability for gross negligence, fraud, or willful misconduct where such limitation is prohibited by law.

13. Indemnification

You agree to defend, indemnify, and hold harmless Thronos Holdings, LLC and its affiliates, officers, employees, agents, and licensors from and against any claims, damages, obligations, losses, liabilities, costs, or expenses (including reasonable attorneys' fees) arising out of (a) your use of the Service, (b) your User Content, (c) your violation of these Terms, or (d) your violation of any applicable law or third-party right.

14. Termination

You may stop using the Service at any time and may delete your account from within the app or by writing to [email protected]. We may suspend or terminate your access at any time, with or without notice, if we believe you have violated these Terms, applicable law, or if your continued use poses a risk to the Service or other users. Sections 7 (license we grant), 9 (intellectual property), 11–14 (disclaimers, liability, indemnification, termination), and 15–17 (governing law, disputes, general provisions) survive termination.

15. Governing law

These Terms are governed by the laws of the State of Texas, USA, without regard to its conflict-of-laws principles, and by U.S. federal law where applicable. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

16. Dispute resolution and binding arbitration

PLEASE READ THIS SECTION CAREFULLY — IT AFFECTS YOUR LEGAL RIGHTS.

Any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules, held in the State of Texas or by videoconference at your option. Judgment on the arbitration award may be entered in any court of competent jurisdiction.

Class action waiver. You and Summara agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class or representative proceeding.

Small claims exception. Either party may bring an individual action in small-claims court instead of arbitration.

30-day opt-out. You may opt out of this arbitration provision by sending written notice to [email protected] within 30 days of first accepting these Terms. Opting out will not affect any other part of these Terms.

17. General
