he can't because he didn't give it those permissions: all the tracking and advertisement bullstuff that is automatically built into the app is what made it
do not download this app, it is clearly malicious. it is not furling's doing, but the app has too many permissions to justify.
if i could prove it was doing something malicious, I would have reported the topic to badspot and gotten it deleted. however, the best I have is hunches based on snippets of compressed code and the declared permissions that suggest it's probably not completely on the level.
again, THIS IS NOT FURLING'S DOING (aside from using such a stuffty service) but do not download the app
Furling doesn't have full control over what gets built into that app. Furling is trustworthy. Are the app developers?
