Privacy Policy
Last updated: July 24, 2026

Local Data Storage
The majority of our apps store all data exclusively on your device using local storage. This data is not transmitted to any server and is deleted when you uninstall the app.
Account-Based Apps
Fun Facts - Did you know? (Ciekawostki) uses a cloud backend for user accounts and content delivery:
- Authentication - Sign in via Apple, Google, or email. Your email address and display name are stored securely in our database hosted in the EU (Frankfurt).
- User data - Likes, saves, collections, and notification preferences are synced to your account via Supabase (PostgreSQL, hosted in EU).
- Advertising - Some apps display ads via Google AdMob, including mediation partners such as Meta Audience Network. These partners may process device identifiers for ad delivery, frequency capping, measurement, and ad personalization where allowed. On iPhone, you can opt out of tracking-based personalization via the App Tracking Transparency prompt and the app privacy settings.
- Analytics and crash reporting - Firebase Analytics collects anonymous usage events (screen views, feature usage). Firebase Crashlytics collects crash reports to help us fix bugs. No personally identifiable information is included in analytics or crash data.
- Push notifications - Firebase Cloud Messaging (FCM) delivers daily fact notifications. Your device token is stored on our server and deleted when you sign out or disable notifications.
- Account deletion - You can permanently delete your account and all associated data from Settings > Delete Account. This action is irreversible and removes all profile data, likes, saves, collections, and device tokens via a server-side cascade.
DeskBreak
DeskBreak does not require an account. Exercise progress, statistics, reminder settings, language, and app preferences are stored locally on your device. Reminder notifications are scheduled locally by iOS.
- Remote configuration - The app may fetch a small configuration file hosted by AppTrick to check compatibility and feature settings. It does not contain your exercise history or reminder schedule.
- Advertising and consent - The free version uses Google AdMob with Meta Audience Network mediation. Google’s User Messaging Platform collects applicable consent choices before ad requests. On iPhone, App Tracking Transparency controls whether tracking-based advertising is allowed. Contextual or non-personalized ads may still be available where permitted.
- Analytics and crash reporting - Firebase Analytics starts disabled and is enabled only after the app’s consent and measurement flow allows it. Firebase Crashlytics may collect release-build crash diagnostics so we can fix reliability problems.
- Premium purchase - Apple processes the one-time Remove Ads Lifetime payment. RevenueCat manages the anonymous purchase receipt and Premium entitlement. AppTrick does not receive your payment-card details.
AI-Powered Features
DreamBook AI and Crystal Lens use AI services to provide dream interpretation and stone identification. When you use these features, the text or image you submit is sent to our AI provider for analysis. We do not store this data on our servers after processing.
Third-Party Services
Depending on the app, we may use the following third-party services:
- Apple App Store - for distribution and in-app purchases
- Supabase - for authentication and cloud database (Fun Facts) - hosted in EU (Frankfurt)
- Google AdMob - for advertising in supported apps - subject to Google's Privacy Policy
- Meta Audience Network - as an advertising mediation partner in supported apps - subject to Meta's Privacy Policy
- Firebase - for analytics and crash reporting in supported apps, and push notifications in Fun Facts - subject to Firebase Privacy Policy
- RevenueCat - for purchase and Premium entitlement management in supported apps
- AI providers - for AI analysis features only (DreamBook AI, Crystal Lens)
In-App Purchases
Some apps offer optional Premium features through Apple’s in-app purchase system. Purchase information is handled by Apple. We use RevenueCat to manage purchase and entitlement status, including one-time purchases and subscriptions where offered, but we do not have access to your payment details.
Children’s Privacy
Our apps do not knowingly collect personal information from children under 13. Our apps are designed to be safe for users of all ages.
Your Rights
For apps that store data locally, you can delete all data by uninstalling the app. For account-based apps (Fun Facts), you can delete your account and all associated data from within the app (Settings > Delete Account). For any data-related requests, contact us at contact@apptrick.dev.
