Notesnook

An end-to-end encrypted note taking alternative to Evernote.

Overview

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. The decision to go fully open source is one of the most crucial steps towards that.

This repository contains all the code required to build & use the Notesnook web, desktop & mobile clients. If you are looking for a full features list or screenshots, please check the website.

Developer guide

Technologies & languages

Notesnook is built using the following technologies:

JavaScript/Typescript — this repo is in a hybrid state. A lot of the newer code is being written in Typescript & the old code is slowly being ported over.
React — the whole front-end across all platforms is built using React.
React Native — For mobile apps we are using React Native
NPM — listed here because we don't use Yarn or PNPM or XYZ across any of our projects.
Lerna & Nx — maintaining monorepos is hard but Nx makes it easier.

Note: Each project in the monorepo contains its own architecture details which you can refer to.
