Notesnook

Notesnook is a note-taking tool that keeps your information completely private through strong encryption. Every note you write gets locked with special codes before leaving your device. This means even if someone breaks into the company's servers, your notes stay unreadable.

The app works across all your devices. You can start a note on your phone during lunch and finish it on your computer at home. Everything syncs automatically while staying protected.

It includes features like password-protected vaults for extra-sensitive notes, web clipping to save articles, and rich text editing with tables, task lists, and code blocks. The entire app is open source, so security experts can check the code to confirm it's truly safe.
