SecureNotes

A secure personal notes application with end-to-end encryption (E2EE), AES-256 encryption for all notes and user data. Designed as a practice project and deployed on Proxmox as a self host solution with a modern dark theme interface.

All notes are encrypted client-side before being sent to the server, ensuring complete privacy without relying on external services.
