Privacy Policy
Last updated: January 2026
The short version
StopBitingNails is designed with privacy as a core principle. The app processes video from your camera locally on your device. No video or images are recorded, stored, or transmitted anywhere. We don't collect personal data.
What data we collect
None. The app:
- Does not record or save video or images
- Does not transmit any data to external servers
- Does not require an account or login
- Does not use analytics or tracking
- Does not collect usage statistics
Camera access
The app requires access to your camera to detect nail biting behavior. The video feed is processed in real-time on your device using machine learning models that run locally. The video stream never leaves your computer.
Open source
StopBitingNails is open source. You can review the entire codebase on GitHub to verify these privacy claims yourself.
Third-party services
The app does not integrate with any third-party services, APIs, or analytics platforms.
Changes to this policy
If we make changes to this privacy policy, we will update this page. Since we don't collect any contact information, we can't notify you directly - but the app is open source, so any changes will be visible in the repository.
