Privacy Policy

Last updated: July 2026

Epic Math Adventures ("EMA", "we", "us") is committed to protecting the privacy of your family. This policy describes what data we collect, how we use it, and your rights.

What We Collect

• Account data: your email address and password (stored via Supabase Auth, never in plaintext)
• Child profile data: name, age, grade levels, selected piece, story genre preferences, and progress data (stone answers, battle scores, concept mastery)
• Usage data: which features are used and when (aggregate, not sold or shared)
• Optional: child photo and parent/companion photo — stored only if you upload them, used only for personalized adventure images

What We Don't Collect

• We do not collect payment card numbers (handled by Stripe directly)
• We do not collect government IDs, social security numbers, or sensitive personal identifiers
• We do not collect school names, class lists, or educational records

How We Use Your Data

• To generate personalized missions for your child
• To track concept mastery and provide parent-facing progress reports
• To maintain your account and subscription
• To improve the product (aggregate, anonymized)

Third Parties

We use the following third-party services, each bound by their own privacy policies:

• Supabase — authentication and data storage
• Railway — application hosting
• Anthropic / OpenAI — AI content generation (prompts contain no personally identifiable information)
• Stripe — payment processing (we never see your card number)

We do not sell your data to any third party. We do not use your data for advertising.

Children's Privacy (COPPA)

EMA is designed for use by families. Children under 13 use the product under parental supervision. We do not knowingly collect data directly from children — all account creation is done by parents. Child profile data (name, age, progress) is associated with the parent account and is not accessible to third parties.

Data Retention & Deletion

You may delete your account and all associated data at any time from your account settings, or by emailing contact@epicmathadventures.com. We will process deletion requests within 30 days.

This is a placeholder privacy policy. It will be reviewed by legal counsel before the public launch of EMA.
