Privacy Policy

Effective Date: 29 March 2026 Last Updated: 30 March 2026

This Privacy Policy describes how Haringey Mobile (“we,” “us,” or “our”) collects, uses, and shares information when you use Primes and Divisibility (the “App”). This app is part of our Math Practice suite, which features a unified account system.

By using the App, you consent to the collection, use, and sharing of your information as described below.

1. Information We Collect

A. Non-Personal Information

We collect anonymized data to improve the educational experience:

Device information (e.g., model and operating system).
Aggregated usage statistics (playtime, features utilized).
Technical performance data and crash reports.

B. Unified Account & Third-Party Services

The App uses the following services to support core functionality:

Firebase Authentication (Unified Account): You may optionally create a user account to sync your “Ad Removal” purchases across devices. This account is shared across all apps in the Math Practice suite. Creating an account in one app allows you to sign in to any other app in the suite using the same credentials.
RevenueCat: Manages your in-app purchase entitlements. It uses an anonymous User ID linked to your Firebase account to ensure your “Ad Removal” status is recognized on all your devices.
Google AdMob: Displays advertisements. For users identified as children, we strictly serve contextual, non-personalized ads.
Native Game Services: Integrates with Apple Game Center and Google Play Games for leaderboards and achievements. These are governed by Apple and Google’s respective privacy policies.
Payment Processing: All transactions are handled securely by the Apple App Store or Google Play Store. We never see or store your credit card details.

2. How We Use Your Information

Unified Access: To authenticate your single “Math Practice” account across our suite of educational apps.
Ad Management: To provide a free experience via AdMob while respecting age-appropriate settings.
App Stability: To fix technical bugs identified via anonymous crash reports.

We do not sell your personal data. Data is shared only with:

Service Providers: Google (Firebase/AdMob), Apple, and RevenueCat solely to provide the app features.
Legal Requirements: If required by law or valid legal process.

4. Children’s Privacy

Primes and Divisibility is an educational app for all ages.

We do not require personal information for basic educational use.
We serve non-personalized, contextually appropriate ads to children.
Accounts are intended for parents or adult users. If you are under the age of majority, please have a guardian manage your account and purchases on your behalf.

5. Your Rights and Choices

Account Deletion: You have the right to delete your account at any time. Because our math apps share a unified system, deleting your account will remove your profile across the entire Math Practice suite. You can request deletion via our Account Deletion Page.
Ad Settings: You can reset your Advertising ID in your device’s system settings to limit ad personalization.
Purchases: Subscription and refund management must be handled through your respective app store (Apple or Google).
