What a Website Sees About You
Your IP address, location, browser and the fingerprint you leave while browsing | Computed in your browser, nothing is stored
How recognisable you are
The more unique details you combine, the easier you are to single out among millions of visitors. This is a rough estimate, not an exact measure.

Privacy
🔒 This page neither stores nor sends your data: the IP address and approximate location are computed by the server only to show them to you, everything else is read by your browser and stays on your device. It is a demonstration, not a data-collection service.
Worried about your privacy or the security of your data?
What an IP address is
The IP address is the number identifying your connection on the Internet, assigned by your provider. Every site you open receives it: without it, it would not know where to reply.
On its own it does not reveal your name, but it exposes the provider and, roughly, the area you browse from. The provider does know who it was assigned to at a given time: that is why the IP is the first thing requested in investigations.
The browser fingerprint
Even without cookies, the combination of browser, system, screen, languages, time zone and graphics card is often nearly unique. By putting these details together, a site can recognise you among millions of visitors: this is browser fingerprinting.
The canvas and WebGL fingerprints above are the most effective example: they exploit tiny differences in how your hardware draws graphics and text.
How to reduce your exposure
- Use a privacy-focused browser and its anti-fingerprinting protections.
- A VPN hides your real IP, but not your browser fingerprint.
- Keep your browser and system updated.
- Enable Do Not Track and Global Privacy Control, keeping in mind not all sites honour them.
IP, VPN and anonymity
Hiding your IP is not the same as being anonymous. A VPN moves the apparent origin of the connection, but browser, cookies and fingerprint stay the same, and the VPN operator still sees your traffic.
Solid privacy needs several measures together: it is one of the topics I offer consulting on.
