What Facebook collects about us

A partial list:

• Facebook records your mouse movements. This helps them recognize that you are not a robot.
• Another way Facebook distinguishes that you're human is by monitoring whether your browser window is "foregrounded or backgrounded."
• Facebook collects a lot of data about your devices, including your battery level, signal strength, and available storage space.
• Your operating system, browser type, file names, and plugins are also fair game.
• Facebook knows your mobile operator (if you're using it on your phone), internet service provider, and IP address, as well as your cookie data, time zone, and internet connection speed.
• Facebook said "in some cases" it monitors devices around its users or on the same network, so it "can do things like help users stream a video from their phone to their TV."
• The signals of your device are also monitored, including Bluetooth and information about nearby Wi-Fi access points. Nearby "cell towers" are also known to Facebook (if you're using it on your phone).
• Facebook hoovers up your GPS location, camera information, and photos if you don't lock down your settings (on your phone or tablet). Call logs and SMS log history are also recorded if users choose to sync their Android devices or upload data.
• Data about your "online and offline actions" and purchases from third-party providers is collected, in addition to information about the "games, apps, or accounts" people use.
