Terms of Use

Effective September 27, 2026

These terms cover your use of the KneeClap apps for iPhone and Android, made by Quyen Dang ("we"). By using the app you agree to them. If you don't agree, please don't use the app.

Your health comes first

• KneeClap is a fitness app, not a medical device, and it does not give medical advice.
• Talk to a doctor before starting a new exercise routine, especially if you have a heart condition, joint problems, are pregnant, or haven't exercised in a while.
• Stop right away if you feel pain, dizziness or shortness of breath.
• Exercise in a safe space with room to move, and hold your phone securely. You are responsible for how and where you exercise.

Rep counts are estimates

The app counts reps from your phone's motion sensors. Counts can be wrong, for example if the phone is held loosely or the movement is small. Don't rely on them where precision matters.

Premium subscriptions

• Premium is an auto-renewing subscription sold through the Apple App Store or Google Play. Prices are shown in the app before you buy and may vary by country.
• If a free trial is offered, it converts to a paid subscription when it ends unless you cancel before then.
• The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it in your App Store or Google Play account settings. Deleting the app does not cancel it.
• Payments, renewals and refunds are handled by Apple or Google under their terms. See Support for how to cancel or request a refund.

License

We grant you a personal, non-exclusive, non-transferable license to use the app on devices you own or control, for your own non-commercial use. Please don't copy, modify, resell, reverse engineer or misuse the app, except where the law allows it.

If you got the app from the App Store, Apple's Licensed Application End User License Agreement also applies. If these terms and Apple's agreement conflict, Apple's agreement wins for the App Store version.

Your data

How the app handles data is described in the Privacy Policy.

No warranty

The app is provided "as is" and "as available". To the extent the law allows, we make no warranties, express or implied, including that the app will be error-free, uninterrupted, or fit for a particular purpose.

Limitation of liability

To the extent the law allows, we are not liable for any indirect, incidental or consequential damages, or for any injury resulting from exercise, arising from your use of the app. Our total liability for any claim is limited to the amount you paid for the app in the 12 months before the claim. Some places don't allow these limits, so they may not apply to you.

Changes

We may update these terms. The date at the top shows the latest version. If you keep using the app after a change, you accept the updated terms.
