What happens to sensitive personal data we give to health, diet and fitness apps? Facebook happily collects much of it despite your best efforts

Testing conducted by the Wall Street Journal showed that Facebook’s software collects data from many apps, regardless of whether a Facebook account is used to log in – or even whether the user is a Facebook member. That’s because Apple and Google app stores don’t require apps to disclose who they share data with, and research showed that in some cases there was almost immediate transfer of information to Facebook. New York State’s Department of Financial Services has issued a detailed report and is investigating Facebook as the result of a call to action by Governor Andrew Cuomo.
