PrivateNotes is a secure note-taking web application that links related ideas into an interactive graph instead of rigid folders. It uses zero-knowledge, client-side AES-GCM 256-bit encryption with PBKDF2-SHA256 key derivation, storing all data locally in the browser's IndexedDB. It works offline-first, requires no account or installation, and supports encrypted ZIP backups.
