Your smart phone has the ability to become an all in one spy device if you aren't careful. Many legitimate apps will request access to your camera, location, and/or microphone, and the only way to find out how this information is being used is to read the licensing agreements.
These agreements can sometimes be long and arduous to read, but it's important to know how and why your data is being collected.
To keep your information safe, use strong, unique passwords and good security software.
