Metronome Lite ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our mobile application on iOS.
We do not collect any personal information. Metronome Lite does not require an account, and we do not ask for your name, email address, location, contacts, or any other personally identifiable information. The app does not use the camera, microphone, photo library, or any other device hardware beyond audio output and haptic feedback.
All app preferences are stored locally on your device only, using Apple's standard UserDefaults API. This data never leaves your device. Preferences stored locally include:
Uninstalling the app removes all of this data.
Metronome Lite offers an optional one-time in-app purchase ("Metronome Lite Pro") to unlock unlimited weekly playback. This purchase is processed entirely by Apple through the App Store using StoreKit. We do not have access to your payment information, credit card details, Apple ID, or any purchase history beyond the fact that the current device has unlocked the Pro entitlement.
For information on how Apple handles your purchase data, please refer to the Apple Privacy Policy.
We do not use any analytics, advertising, or tracking services. We do not collect usage data, crash reports, device identifiers, or any telemetry. We do not share data with third parties because we have no data to share.
Metronome Lite does not make network requests of its own. The only network activity is Apple's StoreKit framework communicating with Apple's servers to process in-app purchases and verify entitlements, which is entirely handled by Apple.
The app is suitable for all ages and does not collect personal information from anyone, including children under the age of 13. We comply with the Children's Online Privacy Protection Act (COPPA) by virtue of collecting no data at all.
Because we do not collect any personal data, there is nothing for us to access, correct, or delete on your behalf. To remove all locally stored preferences, simply uninstall the app from your device.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. Continued use of the app after changes constitutes acceptance of the revised policy.
