## Data Sources

- **DataStore** — user preferences, feature flags, settings
- **JSON assets** — bundled questions (2500+ across 20 categories)

## Build

```bash
cd app/
./gradlew assembleDebug    # Build debug APK
./gradlew installDebug     # Install on connected device/emulator
./gradlew assembleRelease  # Build release APK (minified + shrunk)
```

### Prerequisites

- Android Studio Hedgehog or later
- JDK 17
- Firebase project with Auth, Firestore, Cloud Messaging, and App Check configured
- `google-services.json` in `app/` directory
- RevenueCat project configured for Google Play

## Design Principles

- **Warm & Intimate** — The app should feel like a private emotional space, not a productivity tool
- **Privacy-first** — Data isolated by couple, strict Firestore rules
- **Offline-resilient** — Room cache keeps the app fast without network
- **Intentional** — Short, meaningful interactions. 5 good minutes > endless scrolling
- **2026 modern** — Smooth Material 3 animations, instant feedback, no jank
