Architecture Overview
Atahon is built with a modern tech stack:
| Layer | Technology |
|---|---|
| Framework | Expo SDK 55 + React Native 0.83 |
| UI | NativeWind (Tailwind CSS for RN) |
| Database | SQLite via expo-sqlite + Drizzle ORM |
| State | Zustand (persisted with AsyncStorage) |
| Data fetching | TanStack Query v5 |
| Extensions | Native Kotlin Expo Module bridge |
Your entire library, reading history, and downloaded chapters live in a local SQLite database on your device. No account required, no cloud sync, no telemetry.
