"Apps are Sharing More of Your Data With Ad Industry Than you may Think"

In a new study, researchers analyzed data traffic from ten popular Android apps (which are also all available on iPhones). The ten apps researched include Grindr, OkCupid, Tinder, Clue, MyDays, Perfect365, My Talking Tom 2, Qibla Finder, Happn, and Wave Keyboard. The researchers chose these apps because the apps were likely to have access to highly personal information.  The ten analyzed apps transmit user data to at least 135 different third parties involved in advertising and/or behavioral profiling. The researchers also discovered that all but one of the apps share data beyond the device advertising ID, including a user’s IP address and GPS position, personal attributes such as gender and age, and app activities such as GUI events.
