# Browser Fingerprint See the signals a website can read from your browser with no permission at all — screen, time zone, CPU, canvas and WebGL — combined into a semi-unique hash. A privacy demonstration; nothing is uploaded. ### How it works The page reads freely-available browser properties — user agent, language, screen size and colour depth, time zone, CPU cores, device memory, touch support — plus a **canvas** and **WebGL** render signature, which vary subtly between devices and drivers. These are combined and hashed locally with a fast FNV-1a into one identifier. The point it illustrates: even with cookies blocked, these signals alone can often single out a browser. Nothing here is uploaded or stored. --- *Source: [ocxly.com/browser-fingerprint.html](https://ocxly.com/browser-fingerprint.html) — OCXLY, free 100% client-side privacy-first tools.
