A Survey of Behind-the-Scenes Personal Data Sharing to Third Parties on Mobile

Very interesting write up. It looks like most of the apps are sharing with Google on Android and Apple on iOS. I would be interested in seeing the graphic without them.

Also would be interested in knowing if all of the connections to Facebook are using Facebook to log in, or sharing in secret. Or pinterest connections to twitter, which are likely for sharing purposes.

I am far more interested in which ones are sharing with the unknown 3rd parties.
