This is exactly what any website you visit can read about your browser without asking permission — that's why fingerprinting is possible even with cookies disabled.
How it works
- The page reads standard browser APIs —
navigator,screen,Intl— that any website can access. - It also draws hidden text to a canvas and hashes the pixel output, mimicking the technique real fingerprinting scripts use.
- Everything is displayed back to you immediately, with nothing sent off your device.
FAQ
What is a canvas fingerprint?
Browsers render text and shapes on a hidden canvas slightly differently depending on your OS, GPU, and font rendering — hashing that output gives sites a semi-unique identifier without cookies.
Can I stop websites from fingerprinting me?
Not completely, but privacy-focused browsers (Firefox with resistFingerprinting, Brave, Tor Browser) reduce how unique your fingerprint is by standardizing what these APIs report.
Does disabling cookies stop this?
No — everything shown here comes from browser and device APIs, not cookies, so clearing cookies has no effect on it.
Does this page send my fingerprint anywhere?
No — every value is read and displayed locally; nothing is transmitted or logged.
