Privacy Policy

1. Information We Collect

We collect minimal personal information to provide the application features:

• Account Information: When you sign up, we collect your email address and display name (e.g. child's nickname).
• Gameplay Statistics: We track scores, response speeds, problem accuracy, and badge achievements to calculate difficulty levels and display progress charts.
• Social Login Info: If you sign in via Google OAuth, we receive your email and profile name to create your account. We do not access your contacts, files, or any other Google account details.

2. How We Use Your Information

We use your data solely for educational purposes:

• To personalize your experience (showing your display name).
• To dynamically adjust the math difficulty to suit your speed and skill level.
• To compute progress analytics, show correct/incorrect logs, and award virtual badges.
• We do not display ads, and we do not sell your personal data to anyone.

3. Data Sharing and Third Parties

Your information is stored securely on our database servers managed by Supabase. We do not share, sell, or rent your personal information to third-party advertisers or commercial entities.

4. Children's Privacy

Spark Sums is designed for children. We only collect a display name and email address to manage account progress. We encourage parents and guardians to participate in and monitor their child's online activity. Parents can request account deletion at any time by contacting us.

5. Data Deletion and Security

We implement security measures to protect your account. If you wish to delete your account and clear all associated progress history and profile data, you can do so by contacting support.
