Delete your BatteryShare account

BatteryShare (Android and Wear OS). This deletes your account and all data stored in the cloud for it.

In the app (fastest)

Open BatteryShare on your phone or tablet.
Go to Settings → Cloud sync.
Tap Delete account and confirm. You may be asked to choose your Google account again.

Without the app

Email pixelbearstudioz@gmail.com from the Google account you signed in with, with the subject "Delete my BatteryShare account". It will be deleted within 30 days and you'll get a confirmation.

What is deleted

Your BatteryShare account (Firebase sign-in for your Google account)
All devices and their battery details stored in the cloud
All Find My Device requests stored in the cloud

Nothing is kept after deletion. Battery data stored only on your own devices stays there until you uninstall the app. Your Google account itself is not affected.
