Browser Privacy Check
See the fingerprint your browser exposes: user agent, screen, fonts, canvas, WebGL and more.
Below is the information your browser reveals to any website you visit — together these signals form a “fingerprint” that can identify you even without cookies. Everything except your IP is gathered in your browser and is not uploaded anywhere.
Frequently asked questions
What is a browser fingerprint?
A browser fingerprint is the combination of settings your browser exposes — user agent, screen size, fonts, time zone, graphics hardware and more. Together they can be unique enough to recognise you across sites without any cookies.
Is any of this data sent to your server?
No. Apart from your IP address (which every server necessarily sees), all of the signals on this page are read in your browser with JavaScript and are never uploaded or stored.
What is canvas fingerprinting?
Canvas fingerprinting asks the browser to draw hidden text and graphics, then reads back the pixels. Tiny differences in graphics hardware, drivers and fonts make the result vary between devices, producing a reusable identifier.
How can I reduce my fingerprint?
Use a privacy-focused browser (such as Tor Browser or Brave), keep your browser updated and default, disable unnecessary extensions, and avoid rare fonts or settings. A common, generic configuration is harder to single out.
Does private or incognito mode hide my fingerprint?
Not really. Incognito mode stops your browser storing local history and cookies, but the fingerprinting signals on this page — user agent, screen, hardware, canvas — are exactly the same in a private window.
What can websites do with my fingerprint?
Advertisers and trackers use fingerprints to recognise returning visitors and link your activity across sites even when you block or clear cookies. It can also be used for fraud detection and bot prevention.
