Privacy Policy
Mantle Library is built to be private by design. This policy is short because there is very little to say:
- No accounts. There is nothing to sign up for and nothing to log into.
- No analytics. We do not collect, measure, or transmit any usage statistics.
- No tracking. No cookies, no fingerprinting, no third-party scripts, no beacons.
- No ads. The app contains no advertising and never will.
- No external requests. Every file the app uses — text, styles, scripts, icons, and audio — is bundled with the app itself. Your device never contacts any third-party server.
What is stored on your device
The app uses a service worker to cache its files locally so that it works fully offline. Recordings are cached on your device the first time you play them. All of this data stays on your device, is never transmitted anywhere, and can be removed at any time by clearing your browser's site data.
What we receive
Nothing. Because the app makes no external requests and includes no analytics, we receive no data about you or your use of the library. The static hosting provider that serves the files may keep standard web server logs; consult their policy for details.
