Browser Privacy Snapshot

Below is exactly what your browser exposes to every website you load — no upload, no tracking.
How it works
Every page you load can read these signals. Combined, they form a fingerprint that often identifies your device even without cookies. This page reads them locally and shows them to you — nothing is uploaded.
Methodology
We read the standard Navigator and Screen APIs, plus a small canvas-rendering hash that differs across GPU/font combinations. The values you see here are the same values shared with every site you visit unless you actively block them.
Frequently asked questions
How do I reduce my fingerprint?
Use a privacy-respecting browser (Tor Browser, Brave with strict settings, Firefox with resistFingerprinting enabled). Avoid niche extensions that make you stand out.
Is a unique fingerprint really tracking me?
On its own, a fingerprint is just a hash of properties. Combined with IP, login state and cross-site cookies, it can persistently identify a device over weeks or months.
Why does my canvas hash change between browsers?
Different browsers render text and shapes with different libraries, fonts and anti-aliasing, so the resulting bitmap differs. That is part of why the fingerprint is identifying.
