Metronome is a local-first practice app. This policy explains what information is handled when you use it.
Your tempo, time signature, accent pattern, sound choice, theme, and saved presets are stored locally on your device. We do not operate an account system or server for this data, and we do not receive its contents.
Metronome offers an optional one-time Lifetime unlock. Purchases are processed by Apple. We use RevenueCat to determine whether the unlock is active and to restore it. RevenueCat processes an anonymous app-user identifier and purchase information; it does not receive your name or practice presets. Learn more in RevenueCat's Privacy Policy.
The app declares an iOS microphone-use description because its audio SDK may require audio-session access to play timing clicks. Metronome does not record, upload, or store your audio.
Metronome has no advertising SDK and does not track you across apps or websites. It does not use analytics or sell personal information.
You can delete locally stored Metronome data by deleting the app. For help, contact us through the Support page linked in the app and App Store listing.
If this policy changes, the updated version and date will be published at this same public URL.
