 Der AppHost startet PostgreSQL (Container), wendet EF-Migrationen automatisch an und seedet Testdaten. Die MAUI-App verbindet sich standardmäßig mit `https://localhost:7274` (Android-Emulator: `http://10.0.2.2:5234`).
 
+Für Windows-Entwicklung kann die Client-App ohne persistente lokale Speicherung gestartet werden:
+
+```powershell
+dotnet run --project SlipItIn\SlipItIn.csproj -f net10.0-windows10.0.19041.0 -- --no-storage
+```
+
+In diesem Modus werden weder Token noch lokale Benutzer-, Spiel- oder Offline-Daten gelesen oder geschrieben. Die Sitzung bleibt nur im Arbeitsspeicher der laufenden App erhalten und geht beim Beenden verloren.
