Privacy & Fingerprint Checker

How it works

Every value shown here — the canvas fingerprint, WebGL renderer string, timezone, screen resolution, hardware concurrency — comes straight from standard browser APIs (navigator, screen, Intl.DateTimeFormat, and a 2D canvas context), computed with nothing sent to a server. The canvas fingerprint specifically draws text and a shape to a hidden canvas, reads back the raw pixel data, and hashes it with SHA-256 via the Web Crypto API, since subtle differences in font rendering, anti-aliasing, and GPU produce a slightly different pixel hash on nearly every device.

FAQ

Can two different people ever get the exact same canvas fingerprint?

It's possible but unlikely — the hash mostly reflects your OS's font rendering, GPU, and browser version, so it groups similar device/software combinations rather than identifying one specific person, though combined with everything else on this page it narrows things down considerably.

Will a VPN or incognito mode hide any of this?

No — a VPN only changes your IP address, and incognito mode only avoids saving history and cookies; neither affects canvas rendering, the WebGL renderer string, or screen properties, which is exactly why fingerprinting can still track people who've blocked cookies.
