Why You Should Delete Your Facebook App

A  stark new warning for almost all iPhone users, as Facebook is suddenly  caught “secretly” harvesting sensitive data without anyone realizing.  And worse, there’s no way to stop this especially invasive tracking  other than by deleting the app.

A week ago, I warned iPhone users that Facebook still captures location data using the  metadata from your photos and your IP address, even if you update your  settings “never” to track your location. Facebook admits to this  harvesting, refusing to be drawn on why that’s so wrong when users  specifically disable location tracking.

Now security researchers have suddenly warned that Facebook goes  even further, using the accelerometer on your iPhone to track a constant  stream of your movements, which can easily be used to monitor your  activities or behaviors at times of day, in particular places, or when  interacting with its apps and services. Alarmingly, this data can even  match you with people near you—whether you know them or not.
