✳ A LOCAL-FIRST BROWSER CHECK

Your browser leaves clues.
See what they are.

Explore browser and device signals, see a few local fingerprint measurements, and compare what your browser reports with the network edge. This describes an environment, not a person.

Local signals stay in this tab

When this page loads, it reads browser signals in this tab and makes one normal same-origin request to Keycurio. Keycurio receives your source IP as websites normally do; it does not store your check results. Fingerprint measurements are computed in your browser and are never sent to the site or analytics.

YOUR SNAPSHOT

Ready when you are

The check starts automatically when this page loads. It reads local browser signals and requests this connection’s network metadata from Keycurio.

⌁

SIGNAL COMPARISON
Not checked

Differences are clues about settings or routing, not proof of anything.

ON THIS DEVICE ONLY

Local history

Saving is optional. Only a date and summary count are stored in this browser, never IP, location, fingerprint values or raw signals.

No saved summaries on this device.

A QUICK GUIDE

A fingerprint is a set of signals, not a fixed identity.

Fonts, graphics and browser features can add detail to a site’s view of a browser. A local digest here is a short comparison aid. It is not a guaranteed unique ID, may change across runs or sites, and is never uploaded or included in sharing.

READ THE LIMITS

Differences have ordinary explanations.

A VPN, travel, remote desktop, browser privacy settings, extensions or a custom timezone can make signals differ. This page does not infer nationality, ethnicity, identity, age, politics or risk, and cannot promise anonymity.

NOT INCLUDED

No DNS-leak or service-specific verdict.

The reference project’s DNS resolver probe uses a service that does not allow commercial use, so this page omits it. It also does not classify ChatGPT, Claude or other services, or run hidden third-party probes.

PAGE VISITS & PRIVACY

Google page statistics are automatically enabled on the production site unless a saved refusal, GPC, site-wide statistics opt-out, or a privacy-signal/storage failure applies; this is not a consent click. This page sends only one fixed page-view event. Self-check results, fingerprint digests, IP and network fields are not included in that event; ordinary requests to Google still expose network metadata to Google. Use the control below to turn statistics off or re-enable them after a saved refusal.
