Permissions required by Avast Mobile Security

Data and programming interfaces in Android are protected by permissions. Permissions required by Avast Mobile Security are the minimum set that are needed to implement the functionality. We take your privacy very seriously and we do not use the permissions to transmit private data to our servers or to cause unwanted costs to your phone bill.

The number of required permissions may differ depending on the Android system version and a device model.

Permissions required by Avast Mobile Security are divided into the following groups, which consist of a permission name and short description that explains what the permission does and why the app needs it. This article describes only the most important permissions. To check the full list of permissions on your device:

  1. Open Settings on your device.
