Multiple iOS apps are reportedly sharing sensitive data with Facebook

At least 11 popular apps are reportedly sharing people's sensitive data with Facebook, even if they don't have an account on the social network. The Wall Street Journal found that apps which can help track personal information such as body weight, menstrual cycles and pregnancy are sending such details to Facebook. The apps that were found to share personal data include Flo Period & Ovulation Tracker, BetterMe: Weight Loss Workouts, Breethe, Realtor.com and Instant Heart Rate: HR Monitor. The report suggests none of these apps had an option for users to prevent them from sharing personal data with Facebook, nor do they necessarily make it clear to people their data is making its way to Facebook's servers. The publication was only able to specifically decipher the types of data that iOS apps send Facebook, but a third-party test determined at least one Android fitness app shares weight and height data too.
