Bölüm B – SONNWIN Home Security Uygulaması
The following sections describe data processing in the Android app "SONNWIN Home Security" (available on Google Play Store).
9. Camera and Microphone Access
Purpose: The app uses your device's camera and microphone in Host mode for video surveillance: live streaming, AI motion detection, automatic alarm clips/photos, and two-way audio.
Processing: Camera and audio data are processed exclusively on-device or transmitted via peer-to-peer (WebRTC) directly to the connected viewer device. No video or audio is uploaded to SONNWIN servers. Optionally, alarm clips/photos can be backed up to your Google Drive (see Section 14).
Legal basis: Art. 6(1)(a) GDPR (your explicit consent via Android permissions). You can revoke permissions at any time in device settings.
10. Authentication and User Account
The app requires sign-in via Google Sign-In or email/password. Authentication is handled by Firebase Authentication (Google Ireland Limited). Data processed: email address, Google account ID, authentication token, last sign-in time. Legal basis: Art. 6(1)(b) GDPR (contract fulfillment).
11. Firebase Services
The app uses Firebase services (Google Ireland Limited). Firebase Realtime Database is located in europe-west1 (Frankfurt, Germany).
11.1 Realtime Database: Stores camera assignments, alarm events, user settings. No video/audio content.
11.2 Cloud Messaging (FCM): Delivers push notifications for alarm events.
11.3 Crashlytics & Analytics: The app uses Firebase Crashlytics for crash reporting and Firebase Analytics for anonymous usage statistics. You can opt out in app settings.
12. Advertising (Google AdMob)
The FREE version displays advertisements via Google AdMob (Google Ireland Limited). AdMob may process device identifiers and IP address. PRO subscribers see no ads. Legal basis: Art. 6(1)(a) GDPR (consent via EU consent dialog) and Art. 6(1)(f) GDPR (legitimate interest in financing the free version). You can reset your advertising ID or opt out of personalized ads in your Android settings.
13. WebRTC Streaming & TURN Server
13.1 Peer-to-Peer: The app uses WebRTC for video/audio transmission. In P2P mode, data flows directly between devices without passing through third-party servers.
13.2 TURN Relay: When P2P is not possible, a TURN relay server hosted by netcup GmbH (Karlsruhe, Germany) is used. Authentication uses HMAC-SHA1 signed credentials valid for 5 minutes. Data processed: anonymized user ID, IP address, session timestamp, data volume. Video/audio is only relayed, never stored or analyzed.
14. Google Drive Cloud Backup
The app optionally allows automatic backup of alarm clips and photos to your own Google Drive account. SONNWIN does not store copies. Upload occurs directly from your device using your Google OAuth token. Files are stored in an auto-created folder structure (SONNWIN/Alarms/Date/). Legal basis: Art. 6(1)(a) GDPR (your consent by enabling the backup feature).
15. AI-Based Motion Detection
The app uses an AI model (EfficientDet-Lite2, TensorFlow Lite, Apache 2.0 license) for automatic motion detection. All processing occurs entirely on your device (on-device). No camera images or analysis results are transmitted to external servers.
16. Google Play Billing (In-App Purchases & Subscriptions)
For PRO subscriptions and in-app purchases, the app uses Google Play Billing. Payment processing is handled entirely by Google Play. SONNWIN has no access to your payment methods. We only receive a purchase token, product ID, and purchase time for verification. Legal basis: Art. 6(1)(b) GDPR.
17. Alarm Preview Images (Image Server)
When an alarm occurs, a compressed thumbnail is temporarily stored on our image server (netcup GmbH, Germany) for push notification embedding. Thumbnails are automatically deleted after 30 days.
18. Delete Account and Data
You have the right to delete your SONNWIN account and all associated data at any time.
How to request deletion: Send an email to kontakt@sonnwin.eu with the subject "Delete account". Include the email address you registered with. We process your request within 30 days.
Data that will be deleted: Firebase user account, camera assignments, alarm events, usage quotas, purchase token hashes, temporary alarm thumbnails.
Data we cannot delete: Data in your Google Drive (managed by you), Google Play purchase history (managed by Google), data at Google (Analytics, AdMob — subject to Google's privacy policy).
