# AmiUnique.io

> Free, open-source browser fingerprint test. One click scans 80+ signals (canvas, WebGL, audio, fonts, screen, codecs, WebRTC exposure, network context) locally in your browser and shows how identifiable you are against a live corpus of real scans (~3,200 fingerprints as of July 2026).

Key facts:

- The scan runs only when the visitor clicks the button; nothing is collected before that. Signals are read locally and only derived hashes leave the browser.
- Results use the Three-Lock model: Gold Lock = hardware-level hash (survives browser reinstalls), Silver Lock = software/browser hash, Bronze Lock = full session hash including network context (ASN, TLS, datacenter).
- Privacy: raw IP addresses are never stored — not even hashed. WebRTC candidate IPs are stripped in both directions and never enter the database. Fingerprints are retained at most 90 days; deletion can be requested at /legal/opt-out.
- There is no arbitrary IP lookup: the /ip page reports only on the visitor's own current connection.
- Statistics pages publish aggregate distributions (browser, OS, device, country, screen) from the same corpus, updated continuously at the edge.
- The code is open source (MIT); the service is free with no account.
