An electronic device includes at least one memory unit, a plurality of applications residing on at least one of the memory units and a database residing on at least one of the memory units. The database is configured to store a record specifying a subset of the plurality of applications that are to be inaccessible to a user when in a protected mode of operation. The protected mode is designed for a user (e.g., child or friend borrowing the device) who can potentially use the device with setting that are configured under the primary user's (e.g. parent, device administrator) supervision. The device also includes a user interface through which a primary user and not other users can specify the subset of the plurality of applications to be included in the record. A processor is operatively associated with the memory unit, the database and the user interface. The processor is configured to switch, in response to a request from the primary user and not other users, between a normal mode operation in which all of the applications in the plurality of applications are available for use and the protected mode of operation.
