Privacy Policy
Last updated: April 3, 2026
Your privacy is important to us. Most AppTrick apps store data locally on your device and do not collect personal information. This policy explains what data each app may access and how it is used.

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.
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, crash reporting, and push notifications (Fun Facts) - subject to Firebase Privacy Policy
- RevenueCat - for subscription management in apps with Premium features
- 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 entirely by Apple. We use RevenueCat to manage subscription status but 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.

We may update this policy from time to time. Changes will be posted on this page with an updated date.
