Billing and Refund Policy
1. Plans and pricing
- Free - $0. Includes Unit 1 of the textbook, 5 practice questions per day, and pay-as-you-go help-line credits.
- Premium - $20 per month. Includes all eight units, unlimited practice with exam mode, and 50 help-line credits each month.
2. Help-line credit packs
Any account can buy one-time credit packs for the help line: 10 credits for $3, 20 for $5, 50 for $10, or 150 for $25. Each question costs 1 to 3 credits depending on its difficulty, graded automatically (easy 1, medium 2, hard 3). Purchased credits never expire. Premium's 50 monthly credits refresh on the 1st of each month and do not roll over.
3. Subscription and renewal
Premium is a monthly subscription. It renews automatically each month, and your payment method is charged on your renewal date until you cancel. Payments are processed by Stripe; your card details are handled by Stripe, not stored by us.
4. 14-day money-back guarantee
If you cancel within 14 days of your first subscription payment, you receive a full refund of that first payment, no questions asked. This applies to your first payment only.
5. After the first 14 days
After the 14-day window, subscription payments are non-refundable, including partial months. You can still cancel at any time: cancelling stops all future charges, and your account is then closed and its data deleted.
6. Credit-pack refunds
A credit pack is refundable within 14 days of purchase if none of its credits have been used. Once any credits from a pack are spent, that purchase is final.
7. Cancelling and deleting your account
- Cancel - future charges stop and your account is closed and deleted (outside the 14-day window, no refund is issued).
- Delete your account - this also cancels your subscription automatically, so you are not charged again.
8. Failed payments
If a renewal payment fails, Stripe may retry it over the following days, and access to Premium features may be paused until payment succeeds.
9. Price changes
We may change prices in the future. If we do, we will give you notice before a change affects your renewals, and the new price applies only to billing periods after that notice.
10. How to cancel or request a refund
Cancel from your account settings, or email karayevnihat11@gmail.com from the address on your account and we will handle it, including 14-day refunds.
