However, withdrawal may be restricted for the portion of services already commenced or credits already consumed, in accordance with applicable laws. Where withdrawal is restricted, the Company will clearly indicate the restriction before payment and, where required, provide trial access or equivalent information so that the user’s right to withdraw is not impaired.
2. Refund calculation: When a refund is processed due to withdrawal of subscription or other grounds, the Company will calculate both ① the pro rata amount based on the number of days used and ② the amount corresponding to credits already consumed, apply only the method that results in a smaller deduction (more favorable to the user), and refund the remainder within 3 business days. The two methods are not applied cumulatively. The specific calculation method is announced within the Service before payment.
3. Subscription cancellation: If a subscription is canceled, the user may continue using the Service until the already-paid subscription period expires. The Service will not terminate immediately upon cancellation. A canceled subscription may be restored before the current subscription period expires.
