The Company may change its fee policy, and such changes shall be announced in advance in accordance with the amendment procedure under Article 3. The pre-change fee shall apply to periods for which payment has already been completed.

Mid-month addition of students: If a student is added mid-month, the fee calculated in proportion to the actual number of days the student uses the Service shall be reconciled and charged on the next billing date.
Mid-month removal of students: If a student is removed mid-month, the student may continue to use the Service until the end of the current paid period, meaning until the next billing date.

In either case, no refund will be issued for the current paid billing period, and the reduced student count will be reflected from the next billing date.
Upcoming payment notices: The Company may send upcoming payment notices to the Administrator of the Institutional Member before each monthly billing date, including 7 business days before the billing date, 3 days before the billing date, and on the billing date.

If an overpayment occurs due to the Company’s intent or fault, the Company shall refund the full amount. If an overpayment occurs due to the User’s fault, the User may bear reasonable costs incurred for the refund.
Article 16 (Withdrawal of Subscription)
In accordance with Article 17 of the Act on the Consumer Protection in Electronic Commerce, Users may withdraw their subscription within 7 days from the date of payment or the date on which the Service becomes available.
If a User requests withdrawal within 7 days from the date of payment or the date on which the Service becomes available, the Company shall provide a full refund of the payment amount. In this case, access to the applicable Service will be stopped immediately.
Withdrawal applications may be submitted through the admin page or customer center, and the Company shall process the cancellation or refund within 3 business days of receipt.
Article 17 (Cancellation and Refund Policy)
Full Refund
Users may request a full refund of the payment amount within 7 days of the payment date. In this case, the Company shall provide a full refund of the payment amount, and access to the applicable Service will be stopped immediately.
Cancellation and Refund After 7 Days
If a User requests cancellation after 7 days from the payment date, fees already paid for the current billing cycle are non-refundable.
In this case, cancellation will take effect from the next billing date, and the User may continue using the Service until the end of the current billing cycle. Automatic billing will stop from the next billing date.
Cancellation and Refund Application Procedure
Application Method: Simply “canceling the subscription” means stopping automatic billing from the next payment cycle. If a User wants a full refund within 7 days from the payment date, the User must submit a separate “Refund Request” through the Customer Center or Administrator page.
Approval Period: The Company will complete the internal refund approval within 7 business days from the request date.
Payment Methods and Refund Processing Time
Our services are billed directly through the payment system on our official website; we do not process payments through app markets such as Apple App Store or Google Play Store.
Refund Method: Refunds will, in principle, be processed using the same payment method used for the original transaction. (If a cash deposit is required because the payment method cannot be partially canceled, the refund may be delayed if the User is late in providing bank account information.)
Refund Processing Time: After the Company’s internal approval, it may take an additional 30 days or so for the actual refund to be credited, depending on the independent processing procedures of the payment gateway (PG) and financial institutions. The Company will notify the User in advance in such cases.
Reasons for Refund Restriction
Refunds may be restricted in accordance with relevant laws and these Terms in any of the following cases:
Sharing the account with others without authorization, or using the service for commercial purposes.
Receiving a forced termination measure due to illegally downloading, recording, or distributing learning content without the Company’s prior consent.
When the request is identified as an abusive case, such as unreasonably repeating refunds to interfere with operations.
Article 18 (Protection of Personal Information)
The Company shall make efforts to protect Users’ personal information in accordance with relevant laws including the Personal Information Protection Act. Specific details are set forth in the separate Privacy Policy.
