Free browser privacy test — see what any website knows about you

This site already knows more about you than you think.

One click. No login, no database — everything runs inside your browser and then vanishes. See exactly what any website can work out about you, and who does this to you every single day.

The only thing that ever leaves your browser is a single lookup that turns your IP address into an approximate city. We keep none of it.

What can a website really learn about you?

Every site you open can read far more than most people realise — instantly, and without asking. From your IP address and approximate city to your device, browser, screen, battery, installed fonts, and a unique canvas fingerprint, a page can assemble a detailed profile before you click anything. This free, open tool shows you exactly what is exposed, live in your own browser, and stores none of it.

Frequently asked questions

What information can a website collect about me without permission?
Without a single prompt, a website can read your IP address, approximate city, device type, operating system, browser and version, screen resolution, battery level, installed fonts, GPU, connected cameras and microphones, and a canvas/audio fingerprint. This page demonstrates dozens of these signals live in your own browser.
What is a browser fingerprint?
A browser fingerprint is a near-unique identifier assembled from your device's characteristics — screen size, fonts, GPU, timezone, and more. The Electronic Frontier Foundation found that only about 1 in 286,000 browsers share the same fingerprint, so most people can be recognised across sites without any cookies at all.
Can a website see my exact location?
By default a site only sees your approximate city, derived from your IP address. Pinpoint GPS location — accurate to a few metres — requires your explicit permission, but many apps and sites request it as a matter of routine.
Can websites see my other tabs or which sites I'm logged into?
No. The browser sandbox and same-origin policy stop any page from reading your other tabs, your history, or another site's data. However, a page can still detect the moment you switch away from its tab, the site you arrived from, and — sometimes — which major services still recognise your browser session.
How do I stop websites from tracking me?
Install a content blocker such as uBlock Origin, use a privacy-focused browser (Brave, Firefox, or Tor), deny camera, microphone, location, and clipboard access by default, block third-party cookies, and turn on Global Privacy Control. Together these steps cut off the large majority of trackers.
Does this website store any of my data?
No. Every reading is computed inside your browser and never leaves it, apart from one optional lookup that turns your IP address into an approximate city. Visits are measured only with anonymous, cookieless counts that cannot identify you.
