Privacy Leak Check is a free browser-based tool that shows the connection details a website can see when you visit it. Check your public IP, ISP, approximate location, WebRTC exposure, browser signals and IPv6 availability in one place. No signup, installation or account is required. It is designed as an informational check, not as a security guarantee. The site includes a clearly labeled affiliate disclosure where relevant and does not auto-redirect visitors or claim that a VPN is required.
Hi Product Hunt! I built Privacy Leak Check to make browser privacy signals easier to understand without installing anything or creating an account.
A quick visit shows the basic connection details a website can observe: public IP, ISP, approximate location, WebRTC exposure, browser signals and IPv6 availability.
The goal is clarity, not fear: the tool does not claim that every result is a problem or that anyone must use a VPN. I’d love feedback on which privacy checks would be most useful to add next.
