Are your apps sending highly personal info to Facebook? What you must know

A news report Friday said many smartphone apps were sending highly personal information such as menstrual cycles and body weight to Facebook, without notifying users.

The Wall Street Journal report based on its own in-house tests showed that intimate data could be shared with Facebook using a tool designed to help target ads, even if app users were not members of the leading social network.

Information collected by apps included personal details regarding body weight, pregnancy status, ovulation, and home shopping, according to the Journal.

Facebook said data sharing across apps on iPhones or Android-powered devices is standard industry practice when it comes to how mobile advertising works.
