Most notes apps can read everything you write. Astro Notes cannot — and that is the whole point. Every note is encrypted on your device before launch. The server only ever stores ciphertext. Not us, not a data breach, not anyone else can read your notes. Only you.

Only you hold the key
Your password never leaves your device. There it derives the keys that seal your notes (AES-256-GCM), and a one-time recovery key is your spare. We could not hand your notes to anyone even if we were asked to — we simply do not have them.
Never lose a thought
Notes sync across every device you use and merge cleanly — two devices, or two people, and never a conflict to resolve by hand. Your writing is kept on your device the moment you type it, so a dropped connection, a closed tab or a reload does not take it with them; the note catches up on its own when you are back. Orbit, the paid plan, also remembers every version of a note, so you can travel back and restore anything.
Think together, privately
Share a note with your crew and write in it together, live, with visible cursors — while the note stays sealed end to end. The server relays only ciphertext, even during live collaboration.
Fast enough to keep up with you
Everything is a keystroke away: a command palette, shortcuts for every action, and instant full-text search across your entire archive — which runs on your device, because that is the only place your notes exist in readable form.
Yours to keep, forever
Notes are pure text, and the entire archive exports to ordinary files at any time. Leaving is easy — that is why you can stay with confidence. No lock-in, ever.
Free forever, honest to upgrade
The free plan is genuinely useful: room for hundreds of notes, every security guarantee, search, sync, and export included. Orbit adds note history, live sharing with your crew, five times the storage, and the command bridge — and if it ever lapses, your notes always stay readable and exportable. Current Orbit prices, monthly and yearly in your own currency, are shown in the app once you sign in.
