Report: 11 iPhone Apps Sending Sensitive Data to Facebook
A new investigation has revealed that 11 iOS applications are sending sensitive personal data to Facebook. This sensitive data included personal information such as weight, BMI, menstrual cycles, and sexual activity.
A report from the Wall Street Journal revealed that a popular exercise application was sending a user’s sexual activity information to Facebook. The application has since stopped sending personal data to Facebook.
