ChargeScope — Privacy Policy

Last updated: 4 August 2026

ChargeScope is a battery charging monitor for Android, developed by ZZerker. It collects nothing, sends nothing, and has no servers. Everything it measures stays on your phone.

What data the app reads

ChargeScope reads battery and charging information that Android makes available to any app without requiring permission:

charging current, voltage and battery temperature
battery level, charging status and power source (AC, USB, wireless)
battery capacity, cycle count and state of health, where the device reports them
the device manufacturer and model name, used only to store a per-device calibration profile, because many manufacturers report charging current in inconsistent units

Where that data goes

Nowhere. It is stored in a database on your device and is used only to display live readings and to let you compare recorded charge sessions.

The app has no internet permission and cannot transmit data even in principle.
There is no analytics, no crash reporting, no advertising and no tracking.
Nothing is shared with the developer or with any third party.
No account, sign-in or personal information of any kind is required or requested.

Recorded sessions are deleted automatically after three days. You can delete individual sessions, or all stored data, at any time from within the app. Uninstalling the app removes everything it stored.

Permissions

Permission	Why
`POST_NOTIFICATIONS`	To show the ongoing notification while a charge session is being recorded.
`FOREGROUND_SERVICE` `FOREGROUND_SERVICE_SPECIAL_USE`	To keep recording a charge session while the screen is off. Recording only ever starts when you start it.

The app does not request internet, location, storage, camera, microphone, contacts, or any other permission.

Children

ChargeScope is not directed at children and collects no data from anyone.

Changes

If this policy ever changes, the updated version will be posted at this same address with a new date at the top.
