But do you realize that many apps have access to your personal information such as your contacts list and your GPS location? So what exactly do these apps do with your personal information?
While some apps keep your information private, some might share your information on Facebook, with the app developer - or places that the NSA (National Security Agency) can find it.
Some let you opt out of sharing information if you know where to look and what to change. However, some apps automatically grab your data with no choice to stop them. Rooting out these apps one by one takes time, and you have to read the fine print to see if they're a danger.
