Everything involved, listed by where it physically sits

Last revised 14 September 2026.

By location rather than by category, because location is the thing that actually answers the question.

On the disk of the machine serving this address

A single row for each file sent out: timestamp, path, response code, byte count, the address that asked, the browser string. The server writes them because that is what servers do, and they age out on their own cycle. Beyond those rows the disk holds nothing about a visitor — no database, no table of people, no export.

In your own browser, and never leaving it

Two values live there: whichever theme is in force, and a flag recording that the strip along the bottom has been dealt with. Neither is ever transmitted, so wiping this site's storage erases both and nothing at this end is any the wiser.

Nowhere at all

The age answer, alive for the length of a single click and then not alive anywhere. Any account, since there is no way to create one. Any trace of which page was read, how long the reading lasted or whether the button was used, because nothing capable of producing such a trace is installed.

On machines belonging to other companies

Not a thing of yours, since nothing departs from here at all. There is no measurement service, no ad network, no outside supplier of typefaces, no embedded player from elsewhere. Lettering and scripts come off the same machine as the pages themselves.

On the machines of the room, once you press

Whatever their policy describes, which is longer than this one and theirs to keep. The press is the boundary: before it, this page's inventory applies, and after it nothing on this page does.
