Privacy Policy for Hubble Star

Effective Date: Dec 4 2025

Welcome to Hubble Star (“we,” “our,” “us”). This Privacy Policy describes how we collect, use, and protect your personal information when you use our app and related services (collectively, the “Service”). We are committed to protecting your privacy and complying with all applicable data protection laws, including the Children’s Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR), and other relevant regulations.

1. Information We Collect

We may collect the following information from users:

Personal Information

  • Name or nickname
  • Age or grade
  • Profile photo
  • Email address
  • Account credentials (if applicable)

Usage and Device Information

  • Game progress, quiz scores, and learning activity
  • Device type, operating system, and app version
  • IP address and browser type
  • General location (city or region)
  • Usage analytics collected through Google Analytics and similar tools

Location Data

  • We may collect approximate location based on your device or browser.
  • We do not collect precise GPS data unless you explicitly grant permission.

2. How We Use the Information

We use collected data to:

  • Personalize learning experiences based on age or grade
  • Improve app functionality and performance
  • Enable leaderboard and community features
  • Provide customer support and troubleshooting
  • Display limited advertising in some versions of the app
  • Conduct analytics and usage measurement
  • Comply with legal and safety requirements

3. Advertising and Analytics

Some versions of Hubble Star may include ads. We make every effort to ensure that ads shown to children are age-appropriate based on the information we know. However, mistakes can occur, and we appreciate your understanding. We use Google Analytics and similar tools to analyze aggregated data. These services collect non-identifiable information such as app usage patterns and performance metrics.

4. Children’s Privacy

Hubble Star is suitable for learners of all ages — from Pre-K to adults. For children under 13:

  • We limit data collection to what is necessary for the educational experience.
  • We do not intentionally sell or share personal information with third parties.
  • Parents can control data visibility (public or private profiles) and manage data access directly.

5. Parental Rights and Controls

Parents or guardians have full control over their child’s information. They can:

  • Review or update their child’s profile information
  • Change visibility settings between Public and Private profiles
  • Download all data associated with their child’s account
  • Delete their child’s account and all related data

These actions can be done automatically through the Hubble Star Parent Portal on our website — there is no need to contact us by email for these requests.

6. Data Retention

We retain information only as long as necessary to provide the Service and meet legal obligations. Once data is deleted through the Parent Portal, it is permanently and securely erased from our systems within a reasonable timeframe.

7. Data Security

We use administrative, technical, and physical safeguards to protect user data. While we take every precaution, no security system is completely impenetrable. We are not liable for unauthorized access, security breaches, or hacking incidents beyond our reasonable control.

8. Data Sharing and Sale

We do not intentionally sell children’s personal information to third parties. Limited data may be shared with service providers who help us operate Hubble Star (e.g., hosting, analytics, and ad delivery) — all of whom are required to comply with strict data protection standards.

9. International Transfers

Your data may be processed in countries where data protection laws differ from your own. We ensure that any such transfers comply with applicable privacy standards.

10. Changes to This Policy

We may update this Privacy Policy periodically. The date at the top indicates the most recent revision. Continued use of Hubble Star after updates means you accept the revised Policy.
