Connection privacy

What does your connection reveal?

Your address, roughly where it is, your network, and whether your browser leaks more than you think.

Checked 2 things across 1 outside source.

  1. On our servers

    1. Read the address your connection came from<1 ms
      Shared: nothing: every website you visit sees it

      ClearEvery site you open can see this address.

  2. Outside sources

      ClearA private address: it has no public location.

  3. Back on your device

What this page can see

Your connection, as websites see it

Your IP address100.127.3.57
LocationThe server sees an internal proxy address. Your public location is unavailable.

Checked on your device

  • WebRTC address leak. Needs JavaScript. With it on, your browser asks a public STUN server (Cloudflare's) for your address, the way video calls do, and we compare the answer with the address above.
  • Time zone. Needs JavaScript. Compares your device's time zone with the country your address is in.

Desktop Chrome and Brave hide your local network address behind a random name. Chrome and Firefox on Android can still show local or carrier addresses. A STUN request can show your real public address when a VPN does not carry WebRTC traffic.

What to do

  1. Every website you visit sees your address and roughly where it is. That is normal: it is how pages reach you.
  2. To hide your address from websites, use a reputable VPN, then load this page again with it on and compare.
  3. If you use a VPN, turn on its WebRTC leak protection (or its "kill switch") so your browser cannot go around it.

Small things that help

  • Fitness apps share where you run. In Strava, set a privacy zone around your home and make activities visible to followers only.
  • In California, you can ask every registered data broker to delete your data in one request: the state's DROP service.

GOOD TO KNOW

Frequently asked questions

What can a website tell from my connection?

Your IP address, roughly where it is (often tens of kilometres off, and never a street), which network it belongs to, and whether it is a datacenter or a Tor exit. With JavaScript on, this page also checks whether WebRTC gives away a different address and whether your device's time zone matches that country.

Does a VPN hide my location?

From websites, mostly: they see the VPN's address instead of yours. Load this page with the VPN on and compare. Turn on its WebRTC leak protection too, because a browser can still show your real address through WebRTC when the VPN does not carry that traffic.

What is a WebRTC leak?

WebRTC is how browsers make video calls. To set one up, your browser asks a server for your public address, and a page can read the answer. If your VPN does not carry that request, the answer is your real address.
