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):

https://codeberg.org/CipherApps/cipher-notes

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!
