So, over Christmas break I was shown this website called MyFreeApps where I download free apps and get points, once I get enough points I can cash them in for different types of gift cards. I only ever get iTunes ones though. The only catch is that you have to actually open up the app and use it for awhile, usually only about 30 seconds, and to make sure you do this you have to install something on your device to make sure you are actually using the apps for the required amount of time. I read though what they tell you it does when you install it, and didn't really find that they monitored or stored any info other than how long I was using the apps I downloaded from them.
I am now getting ready to write my paper on mobile devices and all the privacy issues involved in that and have been thinking about what other information they may be taking from me, and also whether or not I care if they are taking it. I think I have come to the consensus that I don't really care that much. There can't be that much information they are taking from my iPad and I am being compensated (the free iTunes gift cards). Also, I am convinced that in order to be able to install software on an iPad (not sure what it is, but it wasn't actually an app) they had to have Apple sign off on it because they typically highly regulate what can and cannot be installed on their hardware, especially mobile stuff, then they can't be taking too much.
lastly, if anyone is interested it is available for iOS and Android I believe
