Mirror
What one visit tells a server, before any cookie or sign-in. The Worker behind it keeps and logs nothing.
Your connection
As the server saw it, from the network and Cloudflare's edge.
Asking the server…
What a script can read
Read in your browser by this page's script, and never sent anywhere.
Headers your browser sent
As they reached the server, without the ones Cloudflare adds. Cookies and credentials are never echoed back.
How it works
A Worker on this subdomain answers /api/mirror with what the request showed it, and keeps nothing: there is no storage, and its logs are off. Only this page may ask; other sites, including the rest of r4v3n.dev, are refused. What a script can read is never sent anywhere.
None of this needs a cookie. Together, the headers and what a script can read are often enough to tell one browser from another, which is why privacy tools try to make them look the same.
