YOUR DIGITAL FINGERPRINT

See what the web
can learn about you.

TraceCheck inspects browser, network, storage, fingerprinting and tracking signals. Core fingerprint calculations stay on your device. External intelligence tests are opt-in and clearly labelled.

Optional: sends your already-public IP address to ipapi.is for VPN, proxy, Tor, hosting and abuse classification. No fingerprint or cookie data is sent.

WebRTC network exposure

ICE candidates visible to page JavaScript

The default scan stays local and does not contact a public STUN service. Use the optional STUN check below if you want to test whether a server-reflexive/public candidate is exposed.

Cookies & storage

What this site can actually store and read

TraceCheck shows the exact value of every cookie that this page can read. HttpOnly cookies and cookies belonging to other websites remain inaccessible to ordinary page JavaScript.

⊘

Tracker/ad-block test

Optional controlled requests to known tracker domains

Not run

This test makes credential-free requests to a small set of known tracking endpoints. Your IP/User-Agent will be visible to those endpoints.

↔

Cross-site & DNS tests

Capabilities that need separate probe infrastructure

TraceCheck includes the probe hooks and deployment source, but a true third-party-cookie or DNS-resolver leak test needs a second registrable domain/authoritative DNS endpoint. We do not fabricate these results.

◆

Deep Cookie Scan

Optional Chrome extension with explicit cookie permission

Extension not queried

With the optional extension, TraceCheck can enumerate cookie metadata across sites, hide values, group by domain, read Chrome's third-party-cookie preference, and cross-reference tracker ownership/categories.

Compare

This browser vs your previous local scan

No earlier scan found

Your fingerprint hash is stored only in this browser so your next scan can be compared locally.

What to do next

Recommendations based on this scan

What this result does not mean

TraceCheck cannot see arbitrary browsing history, passwords, other sites' localStorage, or a tracker company's server-side profile. The scores describe observable signals and tests, not overall computer security.

PRIVACY BY DESIGN

We fingerprint you to explain fingerprinting — not to track you.

Local by default

Canvas, WebGL, audio, fonts, client hints and storage tests are calculated in your browser.

No hidden profile

The core scan has no account or server-side fingerprint history. Previous-scan comparison is stored locally.

Explicit external tests

IP intelligence, public-STUN and tracker-request tests only run after you click their buttons and explain what leaves the browser.
