PHILADELPHIA (CBS) - Think you know what your mobile apps do? You might be surprised.
Researchers at the Carnegie Mellon University Human-Computer Interaction Institute (that’s a fun group of guys) studied 100 Android apps and found that 56 collected location information, device identifiers and/or contact lists and, in many cases, gave the info to marketers.
Not a surprise for a map app, for example, which needs to know your location to give you directions. But you might be surprised that The Brightest Flashlight App also tracks your location and, provided a device ID, same for Shazam Music. And, Pandora Internet Radio tracked your device ID and your contact list. Even Angry Birds app tracks the device ID and location.
