Privacy Policy for Number Ninjas: Math Games

Effective Date: February 1, 2026

This Privacy Policy describes how Number Ninjas: Math Games ("the App," "we," "us," or "our"), developed by David Medawar, collects, uses, and shares information about you when you use our mobile application.

By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

We have designed this App to prioritize privacy and minimize data collection. We do not collect names, email addresses, phone numbers, or photos.

A. Information You Provide

We do not collect any personal information from you. You do not create an account, log in via social media, or provide your real name to play the game or use the leaderboards.

B. Information Generated Automatically

  • Anonymous Player ID: To enable leaderboards and save your progress, we generate a random, anonymous identifier (e.g., a Firebase UID) for your device. This identifier is not linked to your real identity.

  • Game Progress Data: We store data related to your gameplay, such as your high scores, best times, belt achievements, and puzzle streaks. This data is associated with your Anonymous Player ID and stored on secure third-party servers (Firebase) to allow you to compare scores globally without revealing who you are.

  • Usage and Analytics: We use tools like Firebase Analytics to collect anonymous, aggregate data about how the App is used (e.g., "Level 5 is too hard," "Game crashed on start"). This data does not identify you personally and is used solely to improve the game experience.

C. Advertising Data (Non-Personalized)

We use Google AdMob to serve advertisements. We have configured our App to serve Non-Personalized Ads (NPA) to all users.

  • No Tracking: We do not request permission to track you across other apps or websites (App Tracking Transparency).

  • Kid-Safe Settings: We employ Google’s "Tag for Child Directed Treatment," which prevents the creation of advertising profiles and ensures ads are context-based rather than behavior-based.

D. Push Notifications

  • Permission: Requesting permission to send push notifications is entirely optional.

  • Data: If enabled, we use a locally stored reference to your Anonymous Player ID to track your daily puzzle streak.

  • Content: Notifications (such as daily reminders) are generic and generated locally on your device. No personal information is transmitted to send these messages.

2. How We Use Your Information

We use the limited, anonymous data we collect for the following purposes:

  • Game Functionality: To save your progress and ensure you don't lose your belt achievements.

  • Anonymous Leaderboards: To display your score on the global leaderboard. Your entry will appear under an anonymous generated name (e.g., "Ninja 8392") derived from your Anonymous Player ID, protecting your real identity.

  • Engagement: To send optional push notifications regarding your daily streak.

  • Support & Improvement: To fix bugs and optimize game difficulty based on aggregate completion rates.

3. Sharing of Information

We do not sell your personal information. We share anonymous data only with trusted service providers required to operate the game:

  • Google Firebase: Used for secure cloud storage of game progress and anonymous high scores. (View Google's Privacy Policy)

  • Google AdMob: Used to serve non-personalized advertisements. (View AdMob's Privacy Policy)

  • Apple Push Notification Service: Used to deliver optional alerts to your device.

4. Children’s Privacy (COPPA & GDPR-K Compliance)

This App is safe for children. We comply with the Children’s Online Privacy Protection Act (COPPA) and GDPR-K.

  • No PII Collection: We do not knowingly collect personally identifiable information (PII) from children under 13.

  • No Social Login: We have removed all social media logins (Facebook, etc.).

  • Safe Leaderboards: Leaderboards utilize anonymous identifiers and do not allow free-text entry or direct communication between players.

  • Appropriate Ads: All advertising is set to "Non-Personalized" and filtered for "General Audiences" (G-Rated).

If a parent or guardian becomes aware that their child has provided us with personal information without their consent, please contact us, and we will delete such information immediately.

5. Your Rights and Choices

  • Push Notifications: You can disable push notifications at any time in your device’s Settings menu.

  • Data Deletion: Since we do not collect your email or name, we cannot identify you by those means. However, if you wish to reset your progress or delete your anonymous profile, you can simply delete the App from your device. For server-side deletion requests of your Anonymous ID, please contact us with your specific Player ID (found in the app settings, if applicable).

6. Changes & Contact

We may update this policy periodically to reflect changes in our features or legal requirements. We will notify you of changes by updating the Effective Date at the top of this policy.
