What you paste

The contents of the text areas are sent by POST. They therefore do not appear in the URL, and consequently not in the server’s access log, which records only the address requested. They are processed in memory and vanish with the reply: nothing is written to disk, nothing is cached.

The access log keeps, as any web server does, your IP address, the date, the page requested and your user agent.

One single item stored on your side

The word light or dark, and only if you click the theme toggle. It is not a cookie, nothing is sent to the server, and the site behaves identically if you clear it.

No trackers, no third parties

No analytics, no ad network, no share buttons, no remote fonts. The server’s content security policy forbids any resource loaded elsewhere: you can check it yourself, no request leaves this domain.
