Privacy Policy

Your privacy matters, and this app is designed to keep things simple:

No account, sign-up, or login is required to use this app.

No personal data is collected, transmitted, or stored on any server.

All progress data — XP, Listening Rating, streaks, passport stamps, and collections — is stored locally on your device using your browser's local storage. It never leaves your device and I never see it.

This app does not use analytics, tracking, cookies, or third-party advertising.

If you use Challenge Mode to share a link with a friend, the challenge details are encoded directly in the URL itself — nothing is sent to or stored on a server.

If this ever changes (for example, if a future version adds optional cloud sync), this policy will be updated first and the change will be clearly communicated before anything is collected.
