Device Identification
This page is designed to show what technical signals websites on the internet can read about your device. The goal is to make these accessible browser signals understandable.
Why is this approximate?
Hardware identifiers like your CPU or RAM cannot be easily masked because the browser reads them directly from the device to run web applications efficiently. The best way to reduce exposure is keeping your software updated and using privacy-focused browsers.
