About permissions

We require a few permissions to gather the data we show you. On devices running Marshmallow or higher, you don't need to grant any permission on installation, but we'll ask you when we need it and you can decide if you want to grant it or not. All permissions are optional, but some values will be left blank if we can't access the data. Here's a list of the permissions that Android considers dangerous:

Draw over other apps

This is requested when you use the overlay to show you power and CPU usage in real time on top of other apps.

Access app usage stats

We need this to gather the data to calculate per-app power usage. This is an optional feature, it not granted, some parts of the discharging screen will be empty.

Access external storage

We use this for data export, but in the current version of AccuBattery, this feature isn't available yet and this permission is never requested.

We don't require any other sensitive permissions like contacts, email, location, or calendar permissions as we have no intention to use this type of info in the app.

*On a related note, if you send us an email however our ticketing software will create a user account tied to your email address so we can refer to your previous emails when trying to answer questions. If you have sent us emails in the past and now want to remove your email address you can send us an email and our support staff can delete the user account. (If you've never emailed us in the past then there's no need to do this, emailing us in the first place is what leads to the account being created). 

On devices running Lollipop, "access external storage" and "draw over other apps" is granted on installation, but "access app usage stats" still has to enabled by you manually, and you may chose not to if you prefer that.
