Abstract: Systems and methods for proactively deleting applications and/or deactivating permissions granted thereto are described. A system determines a user's usage pattern of an application. The system also determines a standard usage pattern associated with the application. The standard usage pattern may be determined from application usage patterns of multiple users of the system. When the user's usage pattern deviates from the standard usage pattern, the system may cause the application to be deleted from one or more of the user's devices. The system may also deactivate user permissions associated with the application when the user's usage pattern deviates from the standard usage pattern. The system also outputs an indication to the user soliciting whether the system to re-download the application and/or reactivate the permissions.
