XPrivacy

UPDATE NOTE: this app is fully compatible with devices under up to Android 5.1. XPrivacyLua is the successor for next Android versions.

XPrivacy can prevent applications from leaking privacy-sensitive data by restricting the categories of data an application can access. XPrivacy feeds applications fake data or no data at all. It can restrict several data categories, such as contacts or location. For example, if you restrict an application's access to contacts, that application will receive an empty contacts list (don't try this with the contacts application itself without a backup). Similarly, restricting an application's access to your location will send a fake location to that application.

General features:

• Simple to use
• No need to patch anything (no source, no smali or anything else)
• For any stock variant of Android version 4.0.3 - 6.0.1 (ICS, Jelly Bean, KitKat, Lollipop, Marshmallow)
• Newly installed applications are restricted by default
• Displays data actually used by an application
• Option to restrict on demand
• Free and open source
• Free from advertisements
