About Us

This is an independent, free privacy self-check tool. We have a single goal: to let everyday users clearly see how much information the browser they use every day exposes to the websites they visit.

Privacy exposure is often invisible — you do not log in or click "agree"; simply opening a page can let your browser fingerprint, exit IP, timezone, language, even your real public IP be quietly read. We surface these things, normally buried in technical detail, in a clear and readable way, and label what each item leaks.

Our principles

• Local first: fingerprint, WebRTC, and GPS checks run entirely in your browser; results are not uploaded.
• No retention: the server is only used to look up your source IP's ownership in real time — no database, no user profiling.
• Explained: we do not just show results; we explain what each data point means, the risk, and how to reduce it.

What these checks are about

Browser fingerprint: screen, GPU, fonts, canvas/audio rendering, and dozens of other traits combine to identify your device fairly uniquely — without any cookies.

IP information: your exit IP reveals an approximate country/city and your network operator; if it resolves to a datacenter, you are usually on a proxy or VPN.

WebRTC leak: the browser's real-time communication feature can expose your real public IP via STUN without your knowledge — even with a VPN on.

GPS location: unlike coarse IP geo, GPS is accurate to tens of meters, but can only be obtained with your permission.
