Facebook tracks body weight, blood pressure, menstrual cycles and more through apps

Wall Street Journal testing revealed that at least 11 popular apps, with millions of downloads to date, have been sharing highly personal data with Facebook.

Details: When users share their body weight, blood pressure, menstrual cycle, or pregnancy status with certain apps, that information is sent to Facebook and often matched with the Facebook profile of that user.

At least 6 of the top 15 health and fitness apps in Apples iOS store including iFlo Period & Ovulation Tracker and Instant Heart Rate: HR Monitor sent sensitive user data to Facebook immediately after the information was collected.
