"We collect location data using Global Navigation Satellite System (GNSS) (e.g., GPS) and data about nearby cell towers and Wi-Fi hotspots. Other input: data such as the buttons you press on an Xbox wireless controller, skeletal tracking data when you use Kinect, and other sensor data, like the number of steps you take, when you use devices that have applicable sensors."
Microsoft collects a broad range of device data including contacts, biometrics, sensor data, installed software, device identifiers, nearby WiFi access points, and skeletal tracking data โ much of which goes beyond core functionality.
