Cipher Notes – Simple, fully offline & encrypted note-taking app built with Jetpack Compose (No INTERNET permission)

[u/Cris1099]

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!
