An improvement for a system having a processor for running a plurality of applications, a memory storing information relating to use of the applications by a user, a display for displaying application information including the use information, and an input. The improvement includes a privacy toggle which is actuable by the user input to switch between an ON state and an OFF state, and a signal generator which is responsive to the privacy toggle to signal all of the applications of the privacy toggle state. Privacy shields associated with each of the plurality of applications are adapted to prevent display of use information for the user responsive to an ON state signal from the signal generator. The signal generator is a server adapted to register applications which are responsive to a change in state of the privacy toggle, check for a switch of the state of the privacy toggle, and send the signal to registered applications responsive to such a switch. A related method includes the steps of (1) providing a privacy toggle selectively actuable by the user to switch between an ON state and an OFF state, (2) monitoring the privacy toggle in the data processing device at a server, (3) registering the plurality of applications with the server, (4) automatic signaling by the server of all of the registered applications whenever the monitoring step detects a switch in the state of the privacy toggle, and (5) hiding the use information from display in all of the applications when a signal is received from the signalling step indicating a switch of the privacy toggle to the ON state.
