This Privacy Policy describes how Intervals: Timer & Metronome ("the App", "we", "us") handles information when you use the App on your Android device. The App provides a customizable interval timer for focus, meditation, and workout sessions, and a high-precision metronome.
The App stores the following data locally on your device only:
None of this data is transmitted to our servers or any third party. We have no servers.
The App displays banner advertisements served by Google AdMob. AdMob may collect device identifiers (including the Android Advertising ID) and usage data in accordance with Google's Privacy Policy. You can opt out of personalized ads at any time through your device's Google Settings (Google → Ads → Opt out of Ads Personalization).
We do not receive personally identifiable information from AdMob.
| Permission | Why it is needed |
|---|---|
| INTERNET | Required by AdMob to load banner advertisements |
| ACCESS_NETWORK_STATE | Required by AdMob to determine connection type |
| FOREGROUND_SERVICE | Keeps the interval timer and metronome running when the app is in the background |
| FOREGROUND_SERVICE_SPECIAL_USE | Required declaration for our background timer and metronome services on Android 14 and above |
| POST_NOTIFICATIONS | Shows the live countdown notification while a timer is active, and the metronome control notification while it is running |
| VIBRATE | Optional haptic pulse at interval transitions and per metronome beat (opt-in in Settings and in each metronome voice) |
We do not sell, trade, or transfer your information to third parties. The only third-party service integrated into the App is Google AdMob (see Section 2).
All data the App stores lives on your device. You can delete it at any time by clearing the App's data (Settings → Apps → Intervals → Storage → Clear Data) or by uninstalling the App. The App also includes a manual export feature so you can save your cycles to a file of your choosing; that file never leaves your device unless you share it.
The App is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through this App, please contact us so we can take appropriate action.
We may update this Privacy Policy from time to time. Changes will be posted at the URL where this policy is hosted. Continued use of the App after a change constitutes acceptance of the revised policy.
If you have questions about this Privacy Policy, please open an issue or reach out via the contact information listed on the App's Google Play Store page.
