LotteryManager (the "App") respects your privacy. This policy explains how information is handled in the App.
1. Information collected
The App collects the following types of information:
1.1 Information you enter
- Lottery details (organizer, application deadline, purchase deadline, result date, etc.)
- Lottery status (To apply / Applied / Won / Lost / etc.)
- Folder and category settings
- Profile (optional icon and nickname)
This information is stored only on your device (your iPhone) and is never sent to our servers. Uninstalling the App removes all of it.
1.2 Information collected automatically
- Usage statistics (Firebase Analytics): anonymized app open counts, screen transitions, feature usage
- Crash reports (Firebase Crashlytics): technical information about crashes (stack traces, OS version, etc.)
- Advertising identifier (IDFA): collected only when you allow it via App Tracking Transparency (ATT)
2. What we do not collect
- Location (GPS)
- Contacts / address book
- Camera roll or photo library (except images you explicitly pick for the image-recognition feature)
- Microphone / camera
- Personally identifiable information such as name, address, phone number, or payment card details
3. Purpose of use
- Providing the App's features (lottery management, notifications, catalog, etc.)
- Improving the App (analytics and crash reports)
- Displaying advertising (banner ads)
4. Third-party services
The App uses the following third-party services for quality improvement and ad delivery. The information sent is limited to anonymized usage statistics, diagnostic information, and advertising-related data. It does not include personal information such as name, contact details, or address. The third-party services handle the data under their own privacy policies.
- Google Firebase (Analytics / Crashlytics) — anonymized usage statistics and crash information ( privacy policy )
- Google AdMob — advertising ( privacy policy )
We do not provide your personal information to any other third party.
5. App Tracking Transparency (ATT)
On first launch, the App asks for tracking permission via App Tracking Transparency. If you choose "Do not allow", ads will not be personalized, but all features of the App remain fully available.
6. Retention
Data stored on your device is kept until you uninstall the App. Information collected by Firebase Analytics / Crashlytics is deleted on Google's retention schedule.
7. Children's privacy
The App is not intended for use by children under 13. If we learn that a child under 13 has provided information, we will promptly delete it.
8. Deleting your data
To delete data stored on your device, uninstall the App. To request deletion of Analytics / Crashlytics-related information, please contact us via the support page.
9. Changes to this policy
This policy may be updated without prior notice. Material changes will be announced inside the App or on this site.
