What we collect

• Your email address (required for sign-in).
• If you sign in with Google: your name, email, and profile picture.
• Your quiz attempts and scores (so we can show your progress).
• Purchase records (for fulfillment and tax/audit).

What we don't do

• We don't sell your data to anyone.
• We don't run third-party advertising trackers.
• We don't store payment card numbers — payments go through Lemon Squeezy or NOWPayments.

Processors

We use Lemon Squeezy (payments, Merchant of Record), NOWPayments (crypto payments), Resend (email delivery), and Turso (database hosting). Each receives only what's strictly needed to deliver their function.

Deletion

Want your account and data deleted? Email us and we'll remove it within 30 days, retaining only what's required by tax law for purchase records.
