Privacy policy for Battery Glyph

Effective 2 October 2026

Summary

Battery Glyph shows your battery level on the Glyph Matrix on the back of a Nothing phone while it charges.

It does not collect, store, sell or share any personal data. It has no accounts, no ads, no analytics and no internet permission.

What the app accesses

• Battery level and charging state. Android provides these to every app. Battery Glyph reads them to draw the level on the Glyph Matrix, in the foreground and in the background while the phone is plugged in. They are used on the phone and are never saved or sent anywhere.
• Whether the Music Glyph app is drawing. If you have installed Music Glyph, Battery Glyph asks it one yes/no question (is the visualizer using the Glyph Matrix?) so the two apps do not draw over each other. No other information is exchanged.
• Your settings in this app.

What the app does not do

It does not access your contacts, location, files, camera, microphone, messages or notifications. It contains no advertising or analytics software. It shares nothing with third parties.

Background activity

While "Show battery level when plugged in" is on, Battery Glyph runs a small background service that waits for a charger to be connected. Android shows a notification for it. You can turn it off in the app or from that notification.

Data kept and how to delete it

The only thing Battery Glyph stores is your settings (for example the style and brightness you chose). They are kept on your phone, inside the app's private storage, and nowhere else.

To delete them, clear the app's storage in Android's App info screen or uninstall the app. There is nothing held anywhere else to delete.

Security

Battery Glyph has no internet permission, so it cannot send anything off your phone. Everything it does happens on the device.

Children

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

Changes to this policy

If the app's behaviour changes in a way that affects this policy, the policy will be updated in the app and on its web page, with a new effective date.
