Summary

Battery Life & Usage Monitor does not collect, transmit, sell, or share personal data. It has no account, advertising, analytics, tracking, or third-party data SDK.

Data stored on the device

The app stores battery percentage, charge state, timestamps, available device battery readings, and the forecast state derived from those readings. This data is used only to render history, forecasts, telemetry, and the app’s own widgets.

Data remains in local app storage. An Apple App Group shares a limited local snapshot with the app’s widget extensions on the same device.

Retention and deletion

The app retains up to 30 days of battery samples. Recent readings remain at full resolution; older readings may be reduced in resolution to keep local storage bounded while preserving charge-state transitions.

To delete local samples, forecast state, and widget snapshots, open About & Privacy in the app, choose Erase Local History, and confirm.

Background operation

Background refresh is scheduled by the operating system and may not be continuous. The app does not use a remote server to fill gaps or reconstruct device activity.
