Refund policy

Updated October 30, 2026

Paid checkout is not open to customers yet. You can use the first 60 problems for free without providing payment details.

Before paid plans open

The refund window and request process will be published here before paid purchases are enabled. No real payment is required for the current free practice beta.

No automatic renewal

Quarterly, yearly, and lifetime plans are one-time purchases. There is no recurring subscription to cancel. Quarterly and yearly access ends at the end of the purchased period unless you make another purchase.

Your consumer rights

This policy does not limit any refund, cancellation, or other rights provided by applicable law. Contact support with questions about a payment.
