About this demo

This is a front-end only demo using localStorage for users & notes. For real apps, use a secure backend (e.g., Node/Express, Django, Laravel) with a database and proper auth (JWT/sessions, server-side hashing).

• Passwords are hashed (SHA‑256) via Web Crypto API before storage.
• Per-user notes with autosave and note list.
• Export/import .txt, rename, delete, timestamps.
• Works fully offline after first load.
