Let's make the web more private, more secure, faster and decentralized.

readout

Everything below was readable the moment you opened this page. No permission was requested and none of it was measured by asking you.

Nothing here is written down on the server. The client rows are taken in your browser and never leave it — there is no analytics script on this site and no beacon at the bottom of this page. The connection rows are different, and honestly so: your browser hands those to a server before it can be sent anything at all. It answers with them and keeps no copy.

what is deliberately missing

geo
never requested
clip
never read
fonts
not enumerated
canvas
not fingerprinted
audio
not fingerprinted
cookie
none set

Each of these is readable, or close enough to it, and each is left alone. The permission rows above report a state the browser already holds — asking for the state does not prompt you, and nothing on this page ever asks for the permission itself.

what the connection handed over

Read from the headers of one small request this page made to ask what it had been told. The page itself is the same document for every visitor — so that it can be cached — and this is the one part of it that cannot be.

The answer is kept in this tab, in sessionStorage, so every page after this one does not have to ask again. It is your own reading, in your own browser, and it goes when you close the tab. The server kept nothing when it answered.
