At the beginning of this year, a huge scandal started, which focused on applications for mobile terminals that took data from users' smartphones without their attention. The American justice got involved in the problem, forced those from Apple, Google, RIM, etc., to implement a system through which users are warned about the applications that take data from their terminals and thus in iOS 6 the menu was born Privacy. This menu contains the GPS control options, but it also displays information about the applications that take data from: the contact book, the calendar, the reminders application and the Photos application. It all starts with a message like the one above that warns you that an application is requesting access to your data and you have the option to grant access, see more information or deny access.
After you decide whether or not to offer access to your data, you can go to Settings>General>Privacy where you have 5 option menus listed. The first activates/deactivates the GPS function and allows you to offer/block access to GPS for certain functions, and in the following menus you have listed the applications that requested access to each category of information. Inside the menus you have a toggle that allows you to block access to the applications, but if you do this, they could work incorrectly, not having the information they need available.
The Privacy menu is meant to give you total control over how applications use your private data, but the bad part is that we cannot see details about the information accessed and blocking an application will force you to completely or partially abandon it.
