Privacy Policy

The short version

Harpie does not collect, store, or transmit any personal data. Nothing leaves your device.

Microphone

Harpie requests microphone access to detect the pitch of your instrument in real time. Audio is processed entirely on your device using the device's built-in audio pipeline. No audio is recorded, stored, or sent anywhere.

Data we do not collect

We do not collect names, email addresses, location data, usage analytics, crash reports, device identifiers, or any other information that could identify you or your device.

Harpie contains no advertising SDKs, no analytics SDKs, and no third-party code that transmits data.

Settings storage

Your preferences — such as A4 calibration, string count, and display options — are saved locally on your device using the platform's standard storage. This data never leaves your device and is deleted if you uninstall the app.

Children

Harpie does not knowingly collect any data from anyone, including children under 13.
