Everything on your phone is auditable. If anyone were to make any changes to your privacy settings remotely, three things would happen: 1) You would notice because your phone would start collecting data. 2) It would log who did it. 3) Privacy settings can only be changed on a global level, so an admin can’t target a single user to get information, HITS would have to turn it on for everyone.
