Bell curve telemetry
Realtime percentile mapping shows whether you are a statistical outlier or hidden inside the crowd.

AmiUnique.io quantifies how identifiable your browser is against a live corpus of 3,288 fingerprints. The Neo-SaaS interface blends transparency, statistical storytelling, and privacy-first messaging so users understand every signal being collected.
Runs only when you click — nothing is collected before that. ~5 seconds, signals read locally; only derived hashes leave your browser.
Total fingerprints: 3,288 fingerprints have been analyzed
Transparency
Glassmorphism + gradient borders signal that every collector is documented and user controllable.

Realtime percentile mapping shows whether you are a statistical outlier or hidden inside the crowd.
Every collector is documented with lock associations so auditors know exactly what is stored in D1.
WebGL, Canvas, AudioContext, codecs, permissions and TLS fingerprints combine into the Three-Lock system.
We cross-check timezone, locale, UA, and network metadata to spot automation or deliberate spoofing.
Here's something that might surprise you: Every time you visit a website, your browser leaves behind a unique "fingerprint" - and no, we're not talking about cookies.
Think of it like this: Imagine walking into a room and someone could identify you just by the way you walk, the shoes you wear, the watch on your wrist, and the phone in your pocket. They don't need your name. They don't need your ID. They just... know it's you.
That's browser fingerprinting. Websites can identify you by combining dozens of technical details about your browser and device - your screen resolution, installed fonts, graphics card, timezone, language settings, and about 80+ other signals.
The crazy part? You can't delete it like a cookie. It's not stored on your computer. It's calculated fresh every time you visit a site. And it works even in "private" or "incognito" mode.
Researchers have analyzed millions of browser fingerprints at scale. The findings are clear - and honestly, a bit scary:
| Device Type | Uniqueness Rate | Source |
|---|---|---|
| Desktop PC | 35.7% | INRIA Study |
| Mobile Devices | 18.5% | INRIA Study |
| iPhone | 33% | Slido Research |
Did you know?
Slido's research found that within just 24 hours, nearly 10% of deviceschange their fingerprint. But the remaining 90%? They're trackable for weeks or months.
2024 Update
Google announced they will no longer prohibit their advertising customers from fingerprinting users. The UK ICO sharply criticized this move.
Here's the thing - most internet users say they're concerned about online tracking, yet far fewer understand how it actually works. That gap is a problem.
Browser fingerprinting enables:
The good news? Understanding is the first step to protection. That's exactly why we built this tool.
We've developed a "Three-Lock" classification system to help you understand fingerprinting stability:
Canvas rendering, WebGL signatures, audio processing patterns, GPU characteristics. These survive browser reinstalls and even persist across different browsers on the same device.
Installed fonts, browser plugins, language settings, timezone, screen resolution. These change when you update your browser or OS.
IP address, ASN (your internet provider), TLS cipher suites, connection timing. These change when you switch networks or use a VPN.
Look, I'm not going to sugarcoat it - completely avoiding fingerprinting is nearly impossible. But here are practical steps that actually work:
Use Firefox with Enhanced Tracking Protection
Firefox actively resists fingerprinting attempts. Enable "Strict" mode in privacy settings.
Try the Tor Browser for sensitive browsing
Tor standardizes many fingerprint signals, making you blend in with other Tor users.
Keep your browser updated
Updates often include fingerprinting countermeasures. Chrome and Safari are improving too.
Be mindful of browser extensions
Each extension you install can make your fingerprint more unique. Use sparingly.
Consider using multiple browsers
Use different browsers for different activities to compartmentalize your digital identity.
Understand your baseline first
Run our scan to see exactly what makes you unique - knowledge is power.
Browser fingerprinting isn't going away. In fact, as cookies become less reliable for tracking, fingerprinting is becoming more common, not less.
The question isn't whether you have a unique fingerprint - statistically, you probably do. The question is: do you know what it looks like?
We built AmiUnique.io to give you that visibility. No tracking, no data selling - just honest, transparent information about your digital identity. Because you deserve to know.
FAQ
Browser fingerprinting is a technique that collects information about your browser and device to create a unique identifier. This includes your screen resolution, installed fonts, browser plugins, timezone, and many other attributes that, when combined, can identify you across websites — without cookies.
It depends on your device. A large-scale INRIA study of around 2 million fingerprints found 35.7% of desktop browsers and 18.5% of mobile browsers were unique, and Slido research measured about 33% for iPhones. Installed fonts, screen configuration, and graphics hardware contribute the most. Run the scan to see how your browser compares against our live dataset.
While difficult to completely prevent, you can reduce your fingerprint uniqueness by using privacy-focused browsers like Tor or Brave, enabling Firefox strict tracking protection, using standard screen resolutions, and minimizing installed fonts and extensions.
Browser fingerprinting legality varies by jurisdiction. Under GDPR in Europe, it may require user consent. Many websites use it for fraud prevention, security, and analytics. Our tool helps you understand what information is exposed.
AmiUnique.io summarizes your fingerprint into three hashes of increasing scope: Gold Lock (hardware signals that survive browser reinstalls), Silver Lock (software signals tied to your browser installation), and Bronze Lock (the full session fingerprint including network context like ASN and TLS).
No. Your raw IP address is never stored — not even in hashed form. We keep only derived summaries such as network risk context. Fingerprints are retained for a maximum of 90 days, and you can request deletion at any time at /legal/opt-out.
Yes. The scan is free and the code is open source under the MIT license. No account or signup is needed.
