Terms of Service — GutTrack

Last updated: 2026-07-14

These Terms of Service ("Terms") govern your access to and use of the GutTrack mobile application (the "App"), published by Lightbulb Labs LLC, a California limited liability company ("Lightbulb Labs", "we", "us", "our"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. Eligibility

You must be at least 13 years old to use the App. By using the App, you represent that you meet this requirement and have the legal capacity to enter into these Terms.

2. Not medical advice

GutTrack is a personal tracking tool intended to help you record symptoms, food, and bowel movements for your own reference. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Nothing in the App should be relied upon as a substitute for professional medical advice. Always seek the advice of a qualified physician or other healthcare provider with any questions you may have regarding a medical condition, and never disregard or delay seeking professional medical advice because of something you tracked, read, or inferred using the App. If you think you may have a medical emergency, call your local emergency services immediately.

3. Your content

Symptom entries, food logs, meal photos, notes, and any other information you create in the App ("User Content") belong to you. As described in our Privacy Policy, User Content is stored locally on your device — we do not access, view, or store it on any server. You are solely responsible for backing up your own device if you want a copy of your User Content preserved beyond that device.

4. License to use the App

Subject to your compliance with these Terms, Lightbulb Labs grants you a limited, non-exclusive, non-transferable, revocable license to download and use the App on a device you own or control, for your own personal, non-commercial use.

5. Acceptable use

You agree not to:

6. App stores and third-party platforms

The App is distributed through the Apple App Store and/or Google Play. Your download and use of the App is also subject to the usage terms of the applicable app store. If there's a conflict between those terms and these Terms with respect to your use of the platform itself (as opposed to the App), the platform's terms control. Apple and Google are not responsible for the App or its content, and have no obligation to furnish maintenance or support for the App.

7. Intellectual property

The App and all content and technology it incorporates — including its design, text, graphics, logos, and code, and the GutTrack and Lightbulb Labs names and marks — are owned by Lightbulb Labs or its licensors and protected by intellectual property laws. Except for the license in Section 4, no rights are granted to you in the App.

8. Feedback

If you send us suggestions, ideas, or other feedback about the App, you grant us a non-exclusive, worldwide, royalty-free, perpetual, irrevocable license to use that feedback for any purpose, without any obligation to you.

9. Disclaimers

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT ANY DATA WILL BE PRESERVED WITHOUT LOSS, OR THAT THE APP IS ACCURATE, COMPLETE, OR SUITABLE FOR ANY PARTICULAR HEALTH-RELATED PURPOSE.

10. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL LIGHTBULB LABS OR ITS OFFICERS, MEMBERS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE APP — INCLUDING ANY HEALTH-RELATED DECISION MADE IN RELIANCE ON THE APP — WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN ANY EVENT, LIGHTBULB LABS' AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE APP WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US $100).

11. Indemnification

You agree to defend, indemnify, and hold harmless Lightbulb Labs and its officers, members, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in any way connected with your access to or use of the App or your violation of these Terms.

12. Term, termination, and discontinuation

These Terms remain in effect while you use the App. We may suspend or terminate your access to the App at any time, with or without notice, including if we believe you've violated these Terms. We may also modify, suspend, or discontinue the App, in whole or in part, at any time. You may stop using the App at any time by uninstalling it. Sections that by their nature should survive termination — including intellectual property, disclaimers, limitations of liability, and indemnification — will survive.

13. Governing law and venue

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the App will be resolved exclusively in the state or federal courts located in Sacramento County, California, and you consent to the personal jurisdiction of those courts.

14. Changes to these terms

We may revise these Terms at any time by posting an updated version on this page and revising the "Last updated" date. Your continued use of the App after changes are posted constitutes your acceptance of the revised Terms.

15. Miscellaneous

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Lightbulb Labs regarding the App. If any provision is held invalid or unenforceable, the remaining provisions remain in full force and effect. Our failure to enforce any right or provision is not a waiver of that right or provision. You may not assign these Terms without our prior written consent; we may assign them freely.
