Notesnook

Notesnook is a free (as in speech) & open source note taking app focused on user privacy & ease of use. To ensure zero knowledge principles, Notesnook encrypts everything on your device using XChaCha20-Poly1305 & Argon2.

Notesnook is our proof that privacy does not (always) have to come at the cost of convenience. Our goal is to provide users peace of mind & 100% confidence that their notes are safe and secure. Our decision to go fully open source is one of the most crucial steps towards that.

Notesnook is a user focused note taking tool meant to offer a fully end-to-end encrypted note taking experience for everyone. This includes the majority of our less tech savy users who just want to take notes without all the hassle.

In short, Notesnook aims to offer a complete replacement for other insecure note taking tools like Evernote & Notion. Because let's be honest, these tools offer great productivity but at a great cost to your privacy.
