CQBase Ham Quiz Privacy Policy

Data We Process

CQBase Ham Quiz is an amateur radio exam practice app for offline study, practice, mock exams, and missed-question review. The app does not provide CQBase account registration, login, or cloud sync.

Language preference, study progress, answer statistics, missed question IDs, and ad-free state are mainly stored locally on your device.

Advertising And Purchases

The free version displays Google AdMob ads. The Google Mobile Ads SDK may process IP address, advertising identifiers, app interaction data, diagnostics, and approximate region for ad delivery, measurement, fraud prevention, and diagnostics.

The app uses Google Play Billing for a one-time remove-ads purchase. Payment processing, order history, and payment credentials are handled by Google Play. CQBase does not access full payment details.

Data We Do Not Actively Collect

CQBase Ham Quiz does not request or actively collect:

• Name, phone number, contacts, or SMS messages
• Precise location
• Camera, microphone, photos, videos, or files
• Health, financial account, government ID, or biometric data
• Chat content or social relationships

Sharing, Retention, And Deletion

We do not sell your personal data. Some data may be processed directly by Google AdMob, Google User Messaging Platform, Google Play Billing, or Android system backup to provide ads, purchases, and backup features.

Local study data remains on your device until you clear app data or uninstall the app. You can delete local data from Android system settings by clearing CQBase Ham Quiz storage.
