How to use this tool
Overview
Browser Fingerprint Test - See What Identifies You Online shows the fingerprint your browser creates every time you visit a website: a canvas rendering hash, WebGL vendor and renderer strings, screen and viewport size, color depth, timezone, languages, platform, user agent, CPU cores, device memory, touch support and more. Combined, these signals can identify you across sites even without cookies, which is why privacy guides call them a fingerprint. The entire analysis runs locally in your browser — nothing is uploaded. Use the report to see how identifiable you are and to reduce the signals you expose.Frequently asked questions
What is browser fingerprinting? +
Browser fingerprinting identifies you by the combination of technical signals your browser exposes — Browser Fingerprint Test - See What Identifies You Online such as canvas rendering, WebGL, screen size, timezone, languages and hardware. Unlike cookies, these signals cannot be deleted and can link your visits across sites.
Does this test upload my data? +
No. Every signal is computed locally in your browser and never sent to 0Appz or any third party.
Can I stop browser fingerprinting? +
You can reduce it, not eliminate it. Use a mainstream browser with default settings, minimize extensions, block canvas access, and consider browsers that randomize fingerprint values.
Why does my fingerprint change between browsers or devices? +
Each browser exposes a different set of signals — rendering engines, fonts, GPU strings and hardware differ, so fingerprints differ too. That is why the same person can look unique on every device.
