🌸 Bloom Messenger

An open-source, end‑to‑end encrypted mobile messenger.

Bloom is a privacy-first, end‑to‑end encrypted messenger designed for both iOS and Android. Built with React Native and Expo, it focuses on top-tier security without compromising ease of use.

• End‑to‑End Encryption (E2EE): Total privacy for your conversations.
• Post‑Quantum Cryptography: Built for the future to resist advanced threats.
• Cross-Platform: Available on iOS (Note: Android support is currently a Work in Progress).
• Intuitive UI/UX: Designed to be as simple and user-friendly as possible.

Bloom doesn't rely on third-party E2EE frameworks. Instead, it utilizes SKID — a custom post‑quantum encryption protocol based on hybrid cryptography.

• Future-Proof: Specifically designed for post‑quantum security.
• Syncing: Secure cross-device synchronization of private keys.
• Hybrid Primitives: Combines the best of modern cryptographic algorithms.
• Built-in: The SKID protocol source code is implemented and maintained directly within this repository.

• Framework: React Native & Expo
• Language: TypeScript / JavaScript
• Package Manager: pnpm
• Styling: React Native Unistyles

• iOS: 16.0 or higher
• Android: API Level 30+ (Android 11+) Work in progress (not fully supported yet)

1. Clone the repository:

   git clone https://github.com/slipe-fun/Bloom-mobile.git
   cd Bloom-mobile

2. Install dependencies: (Ensure you have pnpm installed)

   pnpm install

1. Prebuild the Expo project:

   npx expo prebuild

2. Start the development build:

   # For iOS
   npx expo run:ios
   
   # For Android
   npx expo run:android

Note for Linux Users (Android Emulator): If you encounter a CommandError stating that the emulator could not be connected, ensure your ANDROID_HOME environment variable is set. Add the following to your ~/.bashrc or ~/.zshrc file and restart your terminal:

export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools

The project follows a standard Expo / React Native architecture. Note: No .env files are used, and there is no runtime environment configuration required.
