Nooto アプリ
Nooto is a note-taking app that keeps your notes private. Everything is encrypted on your device before it ever leaves it, using AES-256-GCM encryption with keys derived locally via Argon2id. Nobody but you, not even the server operator, can read your notes. Features:- Notes are encrypted on-device before sync; the server only ever sees ciphertext
- Works fully offline, no account required to use the app locally
- Optional sync across devices, using the built-in public server or your own self-hosted instance
- Folders, drag-and-drop organization, and a markdown editor
- Fully open source and auditable
