Notesnook Secure Private Notes

Notesnook is a private note taking app that encrypts every note on your device before it ever reaches the cloud. No ads, no trackers, and nobody reading your notes — including us.

⭐ UNLIMITED NOTES, FREE, ON EVERY DEVICE ⭐
Most note apps cap the free plan until it stops being useful. Notesnook does not limit how many notes you write or how many devices you sync. Take notes on your phone, tablet, laptop and browser, and pick up where you left off.
✔️ Unlimited notes and unlimited devices
✔️ 50 notebooks and 50 tags on the free plan
✔️ No ads, no trackers, no countdown

⭐ SECURE NOTES — NO SPYING, NO TRACKING ⭐
End-to-end encryption is always on and cannot be switched off, so it can never be forgotten.
✔️ Encrypted on your device, in transit and at rest
✔️ XChaCha20-Poly1305 and Argon2
✔️ Zero knowledge — even notebook and tag names are encrypted
✔️ Privacy mode blocks screenshots and app previews
✔️ Zero trackers, zero ads, zero telemetry on your notes

⭐ 100% OPEN SOURCE ⭐
Fully open source under AGPLv3 — the apps and the sync server both. Read every line of the code, or run your own server and depend on nobody. Recommended by Privacy Guides.

⭐ A RICH NOTE TAKING EDITOR ⭐
A real editor, not a plain text box.
✔️ Tables, task lists, outline lists and callouts
✔️ Code blocks with syntax highlighting
✔️ Math and chemistry formulas
✔️ Full markdown editor with markdown shortcuts
✔️ Photos, file attachments and embeds
✔️ Note version history and powerful search

⭐ ORGANIZER, PLANNER AND DIGITAL NOTEBOOK ⭐
Nested notebooks, tags, colour notes, favourites, pinned notes and side-menu shortcuts for whatever you open every day. Archive what you are done with instead of deleting it. Search stays instant even at 10,000 notes.

⭐ LINK YOUR NOTES ⭐
Connect notes to one another and build a personal wiki. Open a single note and see everything that links back to it.

⭐ WEB CLIPPER ⭐
Clip any article straight into your notebook from your browser — ad-free, readable and available offline.

⭐ TO DO LISTS AND TASKS ⭐
Manage your day with task lists, shopping lists, grocery lists and outlines. Set reminders that fire on time on every device, including recurring ones.

⭐ QUICK CAPTURE ⭐
✔️ Home screen widget for instant note taking
✔️ Take a note straight from the notification drawer
✔️ Pin a note to your notifications for quick reference
✔️ Share text, links and images into Notesnook from any app

⭐ PRIVATE JOURNAL AND DIARY ⭐
Keep a daily journal, a personal diary or a research notebook that nobody else can open.

⭐ LOCK NOTES, APP LOCK AND VAULT ⭐
Lock the app with a PIN, password or biometrics, and move your most private notes into an encrypted vault behind a second password.

⭐ WORKS OFFLINE ⭐
Write notes offline and jot ideas down with no internet connection at all. Everything syncs, encrypted, the moment you are back online.

⭐ MONOGRAPHS — ENCRYPTED NOTE SHARING ⭐
Publish a note as a shareable link, optionally locked with a password.

⭐ MAKE IT YOURS ⭐
Dark mode, light mode, and a theme builder for making your own.

⭐ IMPORT, EXPORT AND BACK UP ⭐
Bring your old notes across with our importer, and take them away again whenever you like.
✔️ Import from other note apps, plus Markdown, HTML and plain text files
✔️ Export as PDF, HTML, Markdown or plain text
✔️ Encrypted backups you can restore on any device
✔️ Zero lock-in — your data leaves with you
