Frequently asked questions

Are my notes private?

Yes. Notes live only in this browser on this device via IndexedDB. Nothing is uploaded and there is no account.

Do notes sync across devices?

Not automatically. Export a JSON or ZIP backup and import on another device to transfer notes manually.

What if I clear browser data?

Site data clearing deletes your notes. Export backups regularly before clearing cache or switching browsers.

Can I use it offline?

Yes. After the first visit, the app caches locally and auto-save continues without internet.

Does it support Markdown?

Yes — headings, bold, italic, links, lists, task checkboxes, tables, fenced code, math, and Mermaid charts.

Can I export notes?

Export single notes as .md/.html/PDF/.docx, or backup all notes as ZIP or JSON from the sidebar.
