There is no account and no comment form. The pages do not set a tracking cookie and they do not load an analytics script.
Your browser keeps one setting of ours: the light or dark theme, stored in local storage under the key frame-theme (the same key as the FRAME site, so the shared script can stay the same). That value stays on your machine.
The map asks OpenStreetMap for map tiles when you open a page that has a map. That request goes to the OpenStreetMap tile servers, which see your IP address the way any tile request does. The rest of the site does not load third-party images, fonts, or scripts.
GitHub Pages, which serves the site, sees ordinary request logs. We do not publish a contact address yet. Do not send personal information to a guessed mailbox.
