Quote:A newly released study of 34 prominent Android apps found that roughly 68 percent of them share user data with Facebook even when the device operator isn’t actively logged into the social media service or, for that matter, never created a Facebook account.

In such instances, the apps typically communicate to the social media giant when they are opened, closed and actively used, the report indicates. They also relay the user’s device information and general location, all via the Facebook SDK (software development kit).

Moreover, 61 percent of the 34 apps begin automatically transmitting this data immediately, from the very moment the app is opened.

The apps that were found to immediately begin transmitting data to Facebook include such notables as Duolingo, Kayak, Shazam, Spotify Music, TripAdvisor and Yelp. A full list is available here.
