If you’re a regular user of Facebook on Android smartphones, Tinfoil for Facebook is a fantastic app. According the developer, Tinfoil creates a secure mobile sandbox on your Android device, shielding your personal information, privacy, and tracking history. One major feature allows users to control their Facebook’s “Check In” feature, something that could potentially leak your current location without you knowing it.

Previously, Tinfoil for Facebook was banned and removed from the store, and was only recently re-enteered to rave reviews. Want to make your private life a little bit more private? This free mobile, social app is just what you’re looking for.
