Metronome & Tuner ("the app") is built by Apps by BAA. This policy explains what happens with your data — in short: almost nothing leaves your device.
The Tuner and Rhythm Trainer features use your device's microphone to detect pitch and timing in real time. This audio is processed entirely on your device, is never recorded to a file, never stored, and never sent anywhere — including to us. Closing the app or leaving the Tuner screen stops microphone use immediately.
The app does not require you to create an account or sign in. It does not include any analytics, advertising, or tracking software of any kind. We have no way to identify you or see how you use the app.
The app offers a single, entirely optional one-time tip to support development. This purchase is handled directly by Google Play or the Apple App Store — we never see or store your payment details. It does not unlock any feature; every feature is already free to use.
None. The app does not share, sell, or transmit any data to third parties, because it does not collect any data to begin with.
Since the app collects no personal data from any user, it does not knowingly collect data from children either.
If this policy ever changes, the update will be posted on this page with a new "last updated" date.
