4. Device Permissions Used by Our Apps

Our apps use device permissions only to the extent necessary to provide their features. Permissions are used solely for the purposes required by each app’s functionality, and information obtained through them is never transmitted to our servers or any third party without your explicit action.

The types of permissions used differ by app. For the specific permissions used by each app and their purposes, please see that app’s page (app list).

* You can grant or revoke these permissions yourself from your device settings. Features that require a permission cannot be used while that permission is not granted.
