Lucky Decisions App

Privacy Policy

Last updated: June 30, 2026

Lucky Decisions (“the App”) is developed by AlexJKL. This Privacy Policy describes how your information is collected, used, and shared when you use the App.

Information We Collect

The App stores all user-created content (wheels, sectors, spin logs, settings) locally on your device.

Premium subscribers may voluntarily enable Data Sync — a cloud backup feature. When using this feature:

• You sign in via Google or Apple
• We receive your email address and a unique account identifier
• Your app data (wheels, settings, preferences) is saved to Firebase Firestore (Google’s cloud storage)

Use of Data Sync is entirely optional. If you do not sign in, no personal data is transmitted to us or any third party.

The following third-party services are used in the App and may collect certain data:

• Google AdMob — Collects advertising ID, device information, ad interactions (clicks, impressions, which ads you have seen), and SDK diagnostics (crash and performance data) to serve and measure ads. On iOS, personalized ads require your consent via App Tracking Transparency. Google Privacy Policy
• Yandex Mobile Ads — Serves ads and collects advertising ID, device information, ad interactions, and SDK diagnostics. Yandex Privacy Policy
• Meta Audience Network — Serves ads and collects advertising ID, device information, ad interactions, and SDK diagnostics. Meta Privacy Policy
• Unity Ads — Serves ads and collects advertising ID, device information, ad interactions, and SDK diagnostics. Unity Privacy Policy
• RevenueCat — Processes subscription purchases, stores your purchase history, and assigns an anonymous user ID. RevenueCat Privacy Policy
• Firebase (Google) — Crashlytics collects crash and error reports: stack traces, OS version, device model, and installation identifier. Firebase Analytics collects anonymous app usage events and device identifier. Firebase Authentication is used for Google and Apple sign-in when using Data Sync. Firebase Firestore stores app data backups for Premium subscribers who enable sync. Google Privacy Policy

Data Storage

By default, all app data is stored locally on your device. If you enable Data Sync (Premium only), your app data is additionally stored in Firebase Firestore — a Google cloud service located in Europe (region eur3).

Account Deletion

You can delete your account and all associated data at any time:

• In-app: Settings → Data Sync → Delete Account
• Web: alexjkldev.github.io/luckydecisions/delete-account

Deleting your account permanently removes all your cloud data and your Firebase Authentication record. Account deletion does not automatically cancel your Premium subscription.

Children’s Privacy

The App does not knowingly collect personal information from children. The third-party services listed above may have their own age restrictions.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted within the App or on this page.

Contact

If you have questions about this Privacy Policy or want to contact the developer, you can reach out through the App or via the App Store or Google Play Store listing. When you contact us by email, we receive your email address, the content of your message and any attachments. This information is used solely to respond to your inquiry and improve the App. We do not share it with third parties.
