Notesnook
A fully open source, end-to-end encrypted note-taking app that prioritizes user privacy without sacrificing convenience.
What is Notesnook?
Notesnook is an open-source note-taking application that provides end-to-end encryption for all user data. It encrypts notes on the device using XChaCha20-Poly1305 and Argon2 before syncing, ensuring that only the user can access their content. The project aims to offer a privacy-focused alternative to commercial note-taking apps without compromising on usability.
Individuals and organizations who prioritize data privacy and security in their note-taking tools, including journalists, activists, developers, and anyone seeking an encrypted alternative to mainstream note apps.
Developers choose Notesnook because it is fully open source, allowing verification of its encryption claims, and it provides a zero-knowledge architecture where even the service provider cannot access user data. It combines strong security with a multi-platform, user-friendly experience.
