 ### Added
 - **Expanded System Diagnostics**: System Diagnostics copy action now includes active home screen widget counts, system locale, app preferences, database state, and saved crash stack traces.
-- **7 New Locales Supported**: Prepared language picker and resource infrastructure for Czech (`cs`), Spanish (`es`), French (`fr`), Hungarian (`hu`), Italian (`it`), Dutch (`nl`), and Polish (`pl`).
+- **7 New Locales Added**: Integrated complete translations from POEditor for Czech (`cs`), Spanish (`es`), French (`fr`), Hungarian (`hu`), Italian (`it`), Dutch (`nl`), and Polish (`pl`), expanding in-app language picker and system locale support to 8 languages total.

 *   **📈 Rich Telemetry Analysis**: Deep telemetry streams visualization including units, last updated timestamps, coordinates, station type, and exposure type (indoor vs. outdoor).
 *   **🔍 Smart Discovery Engine**: Locate public senseBoxes from the openSenseMap community using direct search by name/ID, location address auto-complete, or on-demand GPS discovery.
 *   **🌡️ Local Unit Conversion**: Per-sensor unit switching for temperature (°C/°F/K), pressure (hPa/mbar/Pa/inHg/mmHg), and wind (m/s/km/h/mph/kn) performed entirely on-device.
-*   **🌐 Multi-Language Support**: BoxViewer currently ships in English and German and is prepared for additional languages (see below)
+*   **🌐 Multi-Language Support**: BoxViewer supports 8 languages (English, German, Czech, Spanish, French, Hungarian, Italian, Dutch, Polish) with POEditor translation integration.
 *   **🔗 Quick Sharing & Deep Linking**: Generate local QR codes to share senseBox stations. Recipients scan the code or open a sharing web link to view the station directly inside the BoxViewer app.
 *   **🔋 Battery & API-Friendly**: Seamless local SQLite caching (`SensorCacheEntity`) and awake-on-unlock widget refresh logic ensure you get fresh data without draining your battery or hammering openSenseMap servers.
 *   **🔒 Privacy-First & De-Googled Friendly**: 100% free of Google Play Services (GMS) dependencies in the app code. Core functionality relies on the native Android `LocationManager` and direct openSenseMap APIs. Address search and location labels may use the device’s native geocoder (ROM-dependent backend) or an OpenStreetMap-based fallback; see the Privacy Policy for details. Zero telemetry, analytics, or third-party trackers.

-BoxViewer adheres to the strict guidelines of modern Android architecture (MVVM / Clean Architecture style) enabling clean decoupling between database layers, networking models, and the UI.
-
-*   **UI Framework**: [Jetpack Compose](https://developer.android.com/jetcompose) (declarative UI with type-safe compose navigation).
-*   **Architecture**: `ViewModel` + `StateFlow` + structured asynchronous coroutine builders (`lifecycleScope`, `collectAsStateWithLifecycle`).
-*   **Local Persistence Layer**: [Room Database](https://developer.android.com/training/data-storage/room) using Kotlin Symbol Processing (KSP) compilation to persist configurations, widgets, and offline caches.
-*   **Networking Server-Client**: [Retrofit 3](https://square.github.io/retrofit/) coupled with [OkHttp 5](https://square.github.io/okhttp/) and [Moshi](https://github.com/square/moshi) to carry out efficient JSON processing of the openSenseMap API.
-*   **Asynchrony Core**: Kotlin [Coroutines](https://kotlinlang.org/docs/coroutines-overview.html) & [Flow](https://kotlinlang.org/docs/flow.html).
-*   **QR Code Utilities**: [ZXing Core](https://github.com/zxing/zxing) barcode image processing library for local generation of station QR sharing codes.
-*   **Core Security Integration**: Secrets Gradle Plugin configured with safe `.env` runtime configurations to decouple keys and configurations from version-control processes.
-*   **Local Testing Ecosystem**: Fully integrated [Robolectric](https://robolectric.org/) testing suites running on high-speed headless JVM surfaces combined with [Roborazzi](https://github.com/takahirom/roborazzi) for visual screenshot regression testing.
