What stays in your browser
Preferences you set — your color theme, a custom palette from the theme builder, the root note you were last working in, and the left-handed diagram setting — are stored in your browser's local storage. They never leave your device, and clearing your browser storage removes them completely.
Server logs
Like every website, the hosting platform (Cloudflare Workers) records standard operational logs — request paths, status codes, and coarse security telemetry — used only to keep the site running and abuse-free.
