Notesnook

Notesnook is a privacy-focused note taking application that puts your privacy first. All your notes are encrypted using XChaCha20-Poly1305-IETF & Argon2 on your device before they are synced. This means that even we cannot read your notes.

Notesnook offers complete privacy with end-to-end encryption, ensuring your notes remain private. It provides seamless synchronization across all devices, rich text editing with markdown support, organized notebooks and tags, and powerful search capabilities. The app is available on all major platforms including web, desktop, and mobile.

Notesnook is ideal for users who prioritize privacy and security in their note-taking workflow. With zero-knowledge encryption, open-source transparency, and cross-platform availability, it provides peace of mind while maintaining excellent functionality. The app offers both free and premium tiers, making privacy-focused note-taking accessible to everyone.
