Privacy policy

Nadvenu Flute Tuner (“the app”) is a musical instrument tuner and metronome. This policy explains what the app does with information on your phone.

Microphone

The app uses the microphone only to hear the note you play and show how close it is to the target pitch. Audio is processed on your phone. It is not recorded, stored, uploaded, or shared with anyone.

Other information

Settings such as reference pitch, theme, and notation stay on your phone. The app does not create an account, does not show ads, and does not sell information.

Permissions

Microphone access is required for tuning. You can turn it off in the phone settings; the tuner will not be able to hear a note until access is allowed again. The screen stays on while the tuner or metronome is running so the display does not sleep during practice.
