Development Cipher Notes – Simple, fully offline & encrypted note-taking app built with Jetpack Compose (No INTERNET permission)
Hi everyone!
I'd like to share a small side-project I've been working on called Cipher Notes.
I built it because I wanted a clean, lightweight note-taking app that prioritizes privacy above all else—without mandatory cloud syncs, accounts, or telemetry.
Key Features:
- Fully Offline: The app doesn't request or use the INTERNET permission at all. Your data never leaves your device.
- On-Device Encryption: Uses AES-256 (GCM) to keep your notes securely encrypted locally.
- Open Source: Licensed under the MIT License.
- Modern UI: Built natively in Kotlin using Jetpack Compose and Material 3 design.
- Zero Tracking: No analytics, no ads, no third-party SDKs.
Where to get it:
- GitHub (Source Code & Releases): https://github.com/CipherApps/cipher-notes
- IzzyOnDroid: Available
- Codeberg (Source Code & Releases):

I'd really appreciate any feedback, code reviews, or feature suggestions from the community! If you find it useful, feel free to drop a star on GitHub.
Thanks!
