Millions of smartphone users confess their most intimate secrets to apps, including when they want to work on their belly fat or the price of the house they checked out last weekend. Other apps know users’ body weight, blood pressure, menstrual cycles or pregnancy status.
Unbeknown to most people, in many cases that data is being shared with someone else: Facebook.
The social-media giant collects intensely personal information from many popular smartphone apps just seconds after users enter it, even if the user has no connection to Facebook, according to testing done by The Wall Street Journal. The apps often send the data without any prominent or specific disclosure, the testing showed.
At this point, none of this should surprise anyone anymore. Still, this particular case involves applications without any Facebook logins or similar mechanisms, giving users zero indiciation that their data is being shared with Facebook. These developers are using Facebook analytics code inside their applications, which in turn collect and send the sensitive information to Facebook.
Other than retreat to a deserted island – what can we even do?
