Notesnook
End-to-end encrypted note-taking app that keeps notes readable only on the user's devices
The product is an end-to-end encrypted note-taking app that keeps personal notes, passwords, and sensitive information readable only on the user's devices, addressing tracking and unauthorized access in conventional note apps. It is for individual consumers who store private personal, health, and administrative notes, including students and teachers via an education plan. Unlike Evernote and other note apps where data can be read elsewhere, it positions as zero-knowledge and fully open source with client-side encryption using XChaCha20-Poly1305 and Argon2.
