Legal

Terms of Use.

These terms govern the Fitbit Kit apps and website.
Last updated September 11, 2026

1. Agreement

By downloading, installing, or using Fitbit Kit, you agree to these Terms of Use and the Privacy Policy. If you do not agree, do not use the app.

2. The product

Fitbit Kit turns your Fitbit activity into contribution grids and lets you track your own activities alongside it. It is free on iOS and Android. There is no paid tier and no subscription. Features may change as we ship updates.

3. Licence

We grant you a personal, non-exclusive, non-transferable licence to use Fitbit Kit on phones you own or control, subject to the rules of the app store you downloaded it from. You may not reverse engineer, resell, or redistribute the app except as allowed by law.

4. Fitbit and health permissions

Fitbit Kit needs permission to read your Fitbit account, and on Android may use Health Connect, so activities can fill themselves in. You are responsible for granting or revoking that access. Fitbit data arrives from Fitbit’s service on Fitbit’s schedule; we are not responsible for delays, gaps, or errors in what your watch recorded or what Fitbit reports.

5. Health disclaimer

Fitbit Kit is a habit-tracking tool, not a medical device. The numbers it shows come from your wearable and may be inaccurate or incomplete. Fitbit Kit does not provide medical advice. Consult a qualified professional before making decisions about your health, fitness, or sleep.

6. Disclaimer

The app is provided “as is.” To the fullest extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, and non-infringement. Use it at your own risk.

7. Limitation of liability

To the fullest extent permitted by law, Yash Vadaria and Fitbit Kit are not liable for indirect, incidental, or consequential damages, or for loss of data or profits, arising from use of the app. Fitbit Kit is free, so our total liability to you is limited to the amount you paid for it: nothing.

8. Third-party trademarks

Fitbit Kit is an independent app and is not affiliated with, endorsed by, or sponsored by Fitbit, Google, or Apple. Fitbit, Pixel, Google Health Connect, and Apple Health are trademarks of their respective owners and are used here only to describe compatibility.

9. Changes

We may update these terms by posting a new version on this page. Continued use after an update means you accept the revised terms.
