Refund Policy
Effective 2026-10-28 · This policy is part of the Terms of Service.
1. Try it before you pay
Test 1 in full and Algo Instant scoring are available without payment. Please use them to see what the paid service is like before you subscribe.
2. Full refund (withdrawal)
If you ask within 7 days of payment, have not used any paid-only content and have not spent any credits, we refund the full amount.
3. Refund after you have started using the service (early cancellation)
Once you have used paid-only content or spent credits, withdrawal is limited for the part that has already been provided (Article 17(2)5 of the Korean Act on Consumer Protection in Electronic Commerce). You can still cancel at any time, and the part you have not used is refunded. There is no cancellation fee.
Refund = amount paid − used portion
The used portion is the amount paid multiplied by the larger of these two ratios:
- Time elapsed: days from the payment date to the cancellation request ÷ days in the billing cycle
- Credits used: credits spent in this cycle ÷ credits granted for this cycle
| Example (₩45,000 incl. VAT · 30 days · 30 credits) | Used portion | Refund |
|---|---|---|
| Cancel on day 10, 6 credits used | larger of 10/30 and 6/30 = 10/30 → ₩15,000 | ₩30,000 |
| Cancel on day 3, 15 credits used | larger of 3/30 and 15/30 = 15/30 → ₩22,500 | ₩22,500 |
| Cancel on day 20, no credits used | 20/30 → ₩30,000 | ₩15,000 |
4. Stopping only the next charge
If you cancel the subscription, you will not be charged from the next billing date. You keep access until the period you already paid for ends. If you would rather be refunded for the remaining period, request early cancellation under section 3.
5. Credits bought separately
If you bought credits separately and ask within 7 days of purchase without having used any of them, we refund the full amount. If some were used, we refund the amount corresponding to the unused credits.
Extra credits (members only, 10 for ₩15,000) are valued at ₩1,500 each. The credits granted for each billing cycle are used first, so extra credits count as used only after those. Extra credits expire when the billing cycle in which they were bought ends, so please request a refund before then. If you cancel your membership early and are refunded, any remaining extra credits are included in that refund.
6. When you could not use the service because of us
If a service outage or another cause on our side kept you from using the paid service, we extend your term by that period or, if you prefer, refund the amount corresponding to it. If what was provided differs from what we advertised, you may withdraw within 3 months of receiving it or within 30 days of learning of the difference.
7. Passes and credits received free of charge
Passes and credits granted without payment (promotions and the like) are not refundable.
8. Payments by minors
If a member under 19 paid without the consent of a legal guardian, the member or the guardian may cancel the payment.
9. When and how refunds are paid
We refund to the original payment method within 3 business days of receiving your request. Card refunds are requested from the card network and may take a few more days to appear, depending on your card issuer. If a refund is delayed for a reason attributable to us, we add the late-payment interest required by law.
10. How to request a refund
Write to satapmed@gmail.com or the contact page from the email address you signed up with. We do not ask for any documents beyond confirming that the request comes from the account holder.
This English version is provided for convenience. Where it differs from the Korean version, the Korean version governs. Nothing in this policy reduces the rights that the consumer-protection law of the country where you live grants you and that cannot be waived by agreement.
