What We Collect

When you sign in with Google, we receive your name, email address, and profile picture. We also collect usage data such as module progress, XP earned, and checkpoint completions.

How We Use Your Data

• To provide and personalize the learning experience
• To track your progress, streaks, and achievements
• To process payments via Stripe (we never see your card details)
• To send transactional emails via Resend (purchase confirmations only)
• To display public profiles and leaderboards (opt-in)

Third-Party Services

• Supabase — database and authentication (your data is stored in Supabase-managed Postgres)
• Stripe — payment processing (PCI-compliant, we never store card data)
• Resend — transactional email delivery
• Vercel — hosting, analytics, and speed insights
• Google OAuth — authentication provider

Cookies

We use essential cookies for authentication sessions. We also use a referral tracking cookie (zts_ref) that stores a referral code and is cleared after sign-up. Vercel Analytics uses privacy-friendly, cookie-less analytics.

You can request access to, correction of, or deletion of your personal data at any time. Email us and we'll respond within 30 days.
