+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Build Commands
+
+```bash
+# Build debug APK
+./gradlew assembleDebug
+
+# Build release APK (with ProGuard/R8 minification)
+./gradlew assembleRelease
+
+# Run unit tests
+./gradlew test
+
+# Run instrumented tests (requires emulator/device)
+./gradlew connectedAndroidTest
+
+# Clean build
+./gradlew clean
+```
+
+APK outputs: `app/build/outputs/apk/`
+
+## Project Configuration
+
+- **SDK**: Compile/Target 34, Min 26
+- **JDK**: 17
+- **Kotlin**: 1.9.22
+- **Package**: `com.fastmask`
+
+## Architecture
+
+Clean Architecture with MVVM pattern. Three distinct layers:
+
+### Data Layer (`data/`)
+- `api/` - JMAP protocol integration (Fastmail's native API)
+  - `JmapApi.kt` - API client with session caching
+  - `JmapService.kt` - Retrofit service interface
+  - `JmapModels.kt` - Kotlinx Serialization models
+- `local/` - Persistence
+  - `TokenStorage.kt` - EncryptedSharedPreferences (lazy-initialized for Hilt compatibility)
+  - `SettingsDataStore.kt` - DataStore for language preferences
+- `repository/` - Repository implementations
+
+### Domain Layer (`domain/`)
+- `model/` - Domain models (`MaskedEmail`, `Language`, `EmailState` enum)
+- `repository/` - Abstract interfaces
+- `usecase/` - Business logic (Login, Logout, CRUD for masked emails, language settings)
+
+### UI Layer (`ui/`)
+- `auth/`, `list/`, `create/`, `detail/`, `settings/` - Feature screens with ViewModels
+- `components/` - Reusable composables (MaskedEmailCard, ShimmerEffect, ErrorMessage)
+- `navigation/` - Jetpack Navigation with shared element transitions
+- `theme/` - Material 3 theming with dynamic colors
+
+## Key Patterns
+
+**State Management**: `StateFlow<UiState>` for reactive state, `SharedFlow<Event>` for one-time events (navigation, logout)
+
+**Dependency Injection**: Hilt with `NetworkModule` (Retrofit, OkHttp, Json) and `RepositoryModule` (repository bindings)
+
+**API Protocol**: JMAP (JSON Mail Access Protocol) with Bearer token auth. Session (accountId, apiUrl) is cached after first call.
+
+**Security**: Tokens stored in EncryptedSharedPreferences using Android Security Crypto library. TokenStorage uses lazy initialization to prevent Hilt injection issues.
+
+## Localization
+
+20 languages supported. String resources in `res/values-*/strings.xml`. In-app language override uses AppCompatDelegate for runtime switching without restart.
+
+## ProGuard/R8
+
+Release builds use minification. Key rules in `app/proguard-rules.pro`:
+- Keep Kotlinx Serialization and JMAP models
+- Keep Google Tink classes (security-crypto dependency)
+- Retrofit and OkHttp configurations
+
+## Commit Message Format
+
+- `Add: new feature description`
+- `Fix: bug description`
+- `Update: what was changed`
+- `Refactor: what was refactored`
