An analysis of 10 highly popular Android apps found what researchers are calling the "out of control" sharing of potentially sensitive information with third parties, in some cases in likely violation of Europe's GDPR privacy regulations.

The findings, which were published in a report issued by the Norwegian Consumer Council (NCC), prompted a coalition of nine consumer advocate and privacy groups to call on federal and state authorities to investigate. Additionally, Twitter has reportedly booted Grindr -- one of the apps detailed in the study -- off of its ad network.

The 10 apps were named as menstrual health trackers Clue and My days; online dating apps Grindr, Happn, OkCupid and Tinder, beauty app Perfect365, the religion app Muslim: Qibla Finder, the game My Talking Tom 2 and keyboard app Wave Keyboard. Cybersecurity company Mnemonic is credited with conducting the technical test on the apps from June through November 2019, checking them for integrated software development kits (SDKs) and other third-party tools that could enable them to record data and share it with partners.
