Each click produces an expanding, fading ring. This demonstrates how precise click coordinates and timing can uniquely identify a user.

Permission-Unlocked Data
Without permission the browser only reveals how many input/output devices exist, with empty labels. Granting access exposes their exact names, stable IDs and full hardware capabilities.
The passive scan only infers fonts by measuring text width. The Local Font Access API returns the exact, complete list of installed fonts — a far stronger signal (Chromium only).
Normally only your current screen is visible. The Window Management API exposes every connected display: its bounds, position, primary/internal flags, color depth and pixel ratio.
IP geolocation is approximate. The Geolocation API returns precise GPS coordinates — often accurate to a few meters — plus altitude, heading and speed when available.
Accelerometer and gyroscope readings expose the device's physical orientation and the unique calibration noise of its sensors — a strong hardware fingerprint (a prompt is required on iOS).

Legal framework
This tool exists only to show you what websites can detect about you. It does not track you across sites, does not build advertising profiles, and does not sell any data. The fingerprinting analysis runs in your browser.
European Union
Sensitive area — read with caution. Article 5(3) of the ePrivacy Directive (transposed in France as Article 82 of the Data Protection Act) requires prior consent to gain access to information stored in a user's terminal equipment. In its Guidelines 2/2023 (version 2.0, October 2024), the EDPB confirms that device fingerprinting falls under Article 5(3): merely "gaining access" to information is enough, independently of any storage. France's CNIL classifies fingerprinting among trackers subject to consent.
To be verified with a lawyer: the exact classification of extension detection under Article 5(3) is not settled by any known case law as of writing. The EDPB and CNIL texts make it very likely that detection for tracking purposes falls under prior consent, but no decision confirms this directly. Nothing categorical is asserted on this point.
United States
There is no single federal privacy law; the US relies on a patchwork of the FTC Act (Section 5, on unfair or deceptive practices) and ~20 state laws. Under California's CCPA/CPRA, fingerprinting data is "personal information", and the definition of a "unique identifier" expressly includes a "probabilistic identifier" — i.e. fingerprinting — treating it as cross-context behavioral advertising. Unlike the EU's prior-consent (opt-in) model, US state laws generally follow a notice-and-opt-out model: sites must disclose the practice and let users opt out of the sale or sharing of that data, and many states (California, Colorado, Connecticut, Texas and others) require honoring the Global Privacy Control browser signal as a binding opt-out.
