Premium, privacy-focused note-taking: high-performance Electron + React + SQL.js with a stunning Cyber aesthetic. Your data stays 100% local.
-0047B3?style=for-the-badge&logo=windows&logoColor=white){kind=icon}
A modern, privacy-focused desktop note-taking application with a modern neon aesthetic. Built with Electron + React + TypeScript, it stores all data locally using SQL.js (SQLite WASM): your notes never leave your device.
Free and open source (GPLv3): no ads, no tracking, and no data collection. Just enjoy it.
Most note apps either sync your data to the cloud (privacy risk) or are too basic to be useful. CyberNotes gives you the best of both worlds: rich editing, powerful organization, and rock-solid security, all 100% offline.
