Notesnook Secure Private Notes

Notesnook is a private notes app with no ads, no trackers and no telemetry on your notes. Every note is encrypted on your device before it ever reaches the cloud, so nobody can read it — including us.

⭐ NO ADS. NO TRACKERS. NO COUNTDOWN. ⭐
Most free note apps pay for themselves with your attention or your data. Notesnook does neither. There is no ad in the app, no analytics on what you write, and no trial clock running in the background.

⭐ UNLIMITED NOTES AND UNLIMITED SYNC ⭐
Notesnook does not limit how many notes you write or how many devices you sync. Notes appear on your phone, tablet, laptop and browser seconds apart, encrypted the whole way.

⭐ PRIVACY YOU CAN VERIFY ⭐
✔️ End-to-end encryption is always on and cannot be switched off
✔️ 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
✔️ No ads, no trackers, no telemetry on your notes
✔️ 100% open source under AGPLv3 — read every line, or run your own sync server
✔️ Recommended by Privacy Guides

⭐ A REAL EDITOR, NOT A TEXT BOX ⭐
✔️ Tables, task lists, outlines and callouts
✔️ Code blocks with syntax highlighting
✔️ Maths and chemistry formulas
✔️ Full Markdown editor with Markdown shortcuts
✔️ Photos, file attachments and embeds
✔️ Note version history and instant search

⭐ ORGANISER, PLANNER AND DIGITAL NOTEBOOK ⭐
Nested notebooks, tags, colours, favourites and pinned notes. Archive what you are finished with instead of deleting it. Search stays instant at 10,000 notes. Link notes together and build your own private wiki.

⭐ JOURNALING AND A PRIVATE DIARY ⭐
Keep a daily journal, a personal diary or a research notebook that nobody else can open. Notes can be locked individually, and Pro adds an encrypted vault behind a second password.

⭐ LOCK NOTES AND APP LOCK ⭐
Lock the app with a PIN, password or biometrics. Pro adds the encrypted vault for the notes you would not want opened even once.

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

⭐ WORKS OFFLINE ⭐
Write with no connection at all. Everything syncs, encrypted, the moment you are back online.

⭐ IMPORT YOUR OLD NOTES ⭐
Bring notes, notebooks and tags across from your old notes app, and from Markdown and HTML files.

Android, iPhone, iPad, Mac, Windows, Linux and the web. Instant encrypted sync and full offline access.

⭐ FREE, FOREVER ⭐
Unlimited notes, unlimited devices, 50 notebooks, 50 tags and full end-to-end encryption. No ads, no trackers, no countdown.
