Connection check.

What every website you visit can see about you — and the small mismatches that give a VPN away.

// Fingerprint

Recognisable without cookies?

A fingerprint is everything your browser reveals that, combined, can recognise you without cookies: your GPU, fonts, screen, audio stack, languages and more. This scan reads ~20 signals the way tracking scripts do. It runs only in this tab — nothing is sent or stored.

// Privacy

What happens to this data.

  • Connection details come from one request to /api/whoami. It answers and forgets: nothing is logged or stored, and the response is never cached.
  • Cloudflare hosts this site, so it handles your request like it does for every page here.
  • WebRTC asks Cloudflare's STUN server for your public address — the same provider, no extra party.
  • The fingerprint scan only runs when you press the button, and its results never leave this tab.
  • Tor status is checked against the public Tor exit list, fetched by the server — your IP isn't sent anywhere.
