Angry Birds Star Wars

What it does: Be careful of free (or nearly free) game apps. Nothing is really free, is it? The most popular game on the iPhone and iPad is Angry Birds Star Wars. Some of the app's risks might turn you into an angry bird, too.

What are the risks: • Can access a user's Location, Calendar and Contacts Book. • Incorporates Flurry Analytics framework, a service used to collect usage data. • Includes file paths to source code files in debug information, stored within the app's executable. These file paths often include usernames or other information related to the app developer or development company. • Uses several ad networks, such as InMobi, AdMob, iAd, Google's Double Click and Millennial Media.
