PushPrivacy is a tweak developed for our iDevices, allowing us to hide the notification texts displayed by our applications in LockScreen. As you already know very well, applications such as Messages can display in the LockScreen a notification with the name of the person who sent us a message, as well as a part of that message. iOS allows us to completely hide this information and only display a notification by which we are notified that we have a new message in an application, without knowing who it comes from.
PushPrivacy works differently from Apple's system, it continues to show us exact information about the application and the person who sent us the message, in the case of messaging applications, but it will not show the text of that message, telling us only that we have a new message. The tweak has a settings menu through which we can choose the applications whose functionality it modifies, and if you want to be interested in using it, then you can find it in the repo http://rpetri.ch/repo/ al Cydia.
