How identifiable is this device?
Sites can combine details like these into a fingerprint that recognizes a device without cookies. Reload this page and the ID stays the same. Some browsers, such as Brave and Firefox with strict protection, scramble parts of it on purpose, and that can make the canvas reading look steady here when it changes between sessions.
Sensors that ask permission
Where you are, plus speed and direction while you move. Uses GPS when it can.
Opens the front or back camera and lists what it can do. The picture stays on this screen.
Shows a live loudness meter and the microphone's settings. Nothing is recorded and nothing plays back.
Opens your browser's list of nearby devices. This page only learns about the one you pick.
Reads the ID and record types of a tag held against your phone. Chrome on Android only.
