On every visit your browser automatically sends along information: your IP address, the browser and operating system, your language preference and more. This tool shows exactly what websites can see about you by default.
What this tool does
The tool reads the data your browser sends with every request and shows it clearly, so you understand what data you share.
How to use it
Open the tool; no input is needed. The information appears immediately based on your current connection.
Input and output
- Input: no input needed
- Output: your IP address, browser and operating system, language preference and other headers
Limitations
The tool shows what is visible through the browser; it is not a full privacy scan and does not measure what external trackers might infer.
Good to know
Your IP address and browser characteristics together form a recognisable fingerprint, even without cookies. To reveal less, use an up-to-date browser with tracking protection and consider a VPN if you want to hide your IP address.
