# Zero Ads, Zero Data Selling: How We Built a Privacy-First Kids App [Urdu content] ## Zero Ads, Zero Data Selling: How We Built a Privacy-First Kids App Amal and Thurayya are completely ad-free, COPPA-compliant, and never sell or share children's data. Voice recordings from speech recognition are processed in real-time and immediately discarded — never stored. The apps use no third-party advertising SDKs, no behavioral tracking for ad targeting, and no in-app purchases that children can accidentally trigger. Revenue comes entirely from parent subscriptions. ### Our Privacy Architecture **No Advertising SDKs** Most free apps include these SDKs for monetization: - Google AdMob - Facebook Audience Network - AppLovin - Unity Ads We include none. Our app bundle contains zero advertising code. ```gradle // pubspec.yaml (Flutter dependencies) dependencies: flutter: sdk: flutter # ✓ Learning, auth, content riverpod: ^2.0 flutter_riverpod: ^2.0 google_cloud_speech: ^0.20 rive: ^0.12 firebase_auth: ^4.0 # ✗ NO AdMob, no Unity Ads, no ad SDKs ``` **Speech Audio Handling** When a child speaks for pronunciation practice: ``` Child speaks: "كتب" ↓ [Device STT] (on-device, no upload) Audio → recognized text → discarded immediately ↓ [Cloud STT] (optional, for accuracy) Audio file → sent to Google Cloud ↓ Google STT processes audio ↓ Audio file is deleted from Google servers Only result (text + timestamps) is returned to app ↓ [App receives results] Audio is never stored in app Audio is never sent anywhere e
