Free tool · Runs in your browser

# What does your browser reveal about you?

This free browser fingerprint test reads the same signals trackers use (canvas, WebGL, fonts, audio, screen, WebRTC and dozens more), then shows you exactly what websites can read from your browser and whether anything looks spoofed. Everything runs locally; nothing is uploaded.

## What is browser fingerprinting?

Browser fingerprinting combines dozens of small details your browser exposes - screen size, graphics card, fonts, time zone, audio stack and more - into a single identifier for your device. Unlike cookies, it needs nothing stored on your machine, so clearing cookies or opening a private window doesn't reset it.

02

## How this test works

The moment this page loads, it reads each signal directly from your browser, hashes them together into the fingerprint above, and runs its own integrity checks for signs of spoofing. All of it happens on your device - no signal, hash or IP address is ever sent to a server.

03

## How to stop fingerprinting

You can't hide every signal, but you can stop them from tying your accounts together. [Donut Browser](https://donutbrowser.com/#download) gives each profile its own consistent, believable fingerprint and proxy, so every identity looks like a different real person instead of one tracked device.

Stay unfingerprintable

## One fingerprint per profile, not one for life

Donut Browser is a free, open-source anti-detect browser. Every profile gets its own consistent fingerprint and proxy, so the signals on this page can't link your accounts to each other or back to you.

## Questions, answered.

### 01 What is a browser fingerprint?

A browser fingerprint is a set of characteristics - your screen, graphics hardware, fonts, language, time zone and more - that together form an identifier for your device. Websites and ad networks use it to recognize you across visits without storing anything on your computer.

### 02 Can I really be tracked without cookies?

Yes. Because a fingerprint is computed from properties of your browser and device, it works even in private/incognito mode, after clearing cookies, and behind a VPN. It's one of the main reasons blocking cookies alone doesn't stop tracking.

### 03 How accurate is this fingerprint test?

It reads the same families of signals professional trackers use, straight from your browser, so every value you see is exactly what a tracking script would read. The integrity score is a transparent estimate, but the signals themselves are accurate.

### 04 Does this tool store or send my data?

No. Every signal is collected and hashed locally in your browser. Nothing - no fingerprint, no IP address, no signal - is uploaded, logged or stored. You can confirm this in your browser's network tab.

### 05 How do I change or hide my browser fingerprint?

Privacy browsers like Tor and Brave randomize some signals, and hardened settings help, but the most reliable option for managing multiple identities is an anti-detect browser. Donut Browser gives every profile a distinct, consistent fingerprint so your accounts stay separate.

### 06 How is this different from other fingerprint checkers?

Most checkers do one of two things: list the raw signals, or tell you whether your browser looks tampered with. This page does both - the full per-signal breakdown plus tamper and spoofing detection that flags when a browser is lying about who it is - and every check runs on your device.
