Cube AppLock requires the following app permissions:
• App Usage - used to retrieve the list of installed apps, available for locking, and manage their lock status.

Cube AppLock enables you to configure a broad range of settings right away - the first time you’re using the app. Let’s see how it works.
• Open Cube AppLock.
