The Norwegian Consumer Council published an analysis of how popular apps are sharing user data with the behavioral ad industry. TechCrunch reports the findings: A majority of the apps that were tested for the report were found to transmit data to “unexpected third parties” — with users not being clearly informed about who was getting their information and what they were doing with it. Most of the apps also did not provide any meaningful options or on-board settings for users to prevent or reduce the sharing of data with third parties. “The evidence keeps mounting against the commercial surveillance systems at the heart of online advertising,” the Council writes, dubbing the current situation “completely out of control, harming consumers, societies, and businesses,” and calling for curbs to prevalent practices in which app users’ personal data is broadcast and spread “with few restraints.”
In the report, app users’ data is documented being shared with tech giants such as Facebook, Google and Twitter — which operate their own mobile ad platforms and/or other key infrastructure related to the collection and sharing of smartphone users’ data for ad targeting purposes — but also with scores of other faceless entities that the average consumer is unlikely to have heard of. […] Among the findings are a makeup filter app sharing the precise GPS coordinates of its users; ovulation, period and mood-tracking apps sharing users’ intimate personal data with Facebook and Google (among others); dating apps exchanging user data with each other, and also sharing with third parties sensitive user info like individuals’ sexual preferences (and real-time device specific tells such as sensor data from the gyroscope…); and a games app for young children that was found to contain 25 embedded SDKs and which shared the Android Advertising ID of a test device with eight third parties. The 10 apps whose data flows were analyzed for the report are the dating apps Grindr, Happn, OkCupid, and Tinder; fertility/period tracker apps Clue and MyDays; makeup app Perfect365; religious app Muslim: Qibla Finder; children’s app My Talking Tom 2; and the keyboard app Wave Keyboard.
