Until Ducks for Android
All your study data stays on your device. Nothing is sent to our servers.
Your Data Stays Local
All study sessions, progress, and settings are stored locally on your Android device. Your notes, timers, and duck configurations stay on your device. If you buy a subscription, lifetime access, or any other paid service in the app, a limited identifier may be processed to validate your purchase.
Payments via Superwall
In-app purchases are processed through Superwall and Google Play. We do not store full payment card details ourselves. We only use the limited purchase or account identifiers needed to validate subscriptions, lifetime access, or other paid services.
Analytics & Crash Reports
The app sends anonymous usage data and crash reports to Google Firebase and Superwall to help improve the app. This includes basic usage statistics like session frequency and app performance. No personally identifiable information is collected.
