Article 14 (Cancellation and Refund Policy)

1. Cancellation Period

Members who have entered into a paid service agreement with the Company may request a cancellation within 14 days of the contract date or the content delivery date, whichever is later. However, cancellation may be restricted in the following cases.

Services the member has already fully taken or used
Services provided free of charge through events, promotions, etc.
Cases where the service has been lost or damaged due to the member’s fault
Other cases specified in the “Act on the Consumer Protection in Electronic Commerce, Etc.”

The cancellation restrictions in Paragraph 1 apply only if the Company has stated them in advance in a place where users can easily see them.

Notwithstanding Paragraph 1, if the service differs from what was displayed or advertised, or is performed differently from the contract, the member may cancel within 3 months of the date the service was supplied, or within 30 days of the date the member learned or could have learned of that fact.

2. Refund Standards

The Company will issue refunds to members under the standards below within 5 business days from the date the grounds for a refund arise.

All of the Company’s products are digital downloads and online course bundle packages, so they are subject to the Company’s own refund policy. This policy follows the tuition refund standards in Appended Table 3 under Article 28(4) of the “Lifelong Education Act.”

The Company refunds tuition under these standards, which means refunds are available only for lessons the member has not watched. In other words, the per-lesson price is calculated by dividing the amount paid by the number of paid lessons, and the refund is the amount paid minus the cost of the lessons watched.

3. How Refunds Are Calculated

The course start date is counted from the payment date. For pre-order courses, it is counted from the course launch date.
Refund amounts are calculated based on the actual amount paid.
Free orientation (OT) videos and similar content are excluded from the video count used for refunds.
Playing a video counts as having watched it.

Refund Formula

Refund amount = (Actual amount paid ÷ total number of paid lessons in the product) × number of unwatched lessons

What counts as watched: A video is considered watched if a playback record exists, and played lessons are excluded from the refund. Viewing status is determined by the records in the Company’s learning management system.

4. Refund Eligibility

If no videos have been watched: 100% of the amount paid is refundable
After watching videos or accessing digital download files: the per-lesson price is calculated by dividing the amount paid by the number of lessons, and the amount paid minus the cost of the lessons watched is refunded
If all videos have been watched: no refund

5. Payment Plans

For subscription plans, one paid lesson is released each week. The per-lesson price is calculated by dividing the amount paid by the number of lessons released during the subscription period, and the amount paid minus the cost of the lessons watched is refunded.

For single-product purchases, the per-lesson price is calculated by dividing the amount paid by the number of lessons included in the product, and the amount paid minus the cost of the lessons watched is refunded.

The number of paid lessons per month is counted as 4 per subject, regardless of the actual number of calendar weeks.

For products made up of multiple subjects, the monthly lesson count is (number of subjects × 4). (e.g., 2 subjects = 8 lessons, 3 subjects = 12 lessons)

For annual subscription products, the lesson count is (number of subjects × 24). (e.g., 1 subject = 24 lessons, 2 subjects = 48 lessons, 3 subjects = 72 lessons)

Free OT and other orientation-type videos are excluded from the lesson count.

6. After the Access Period Ends

Once the Access Period stated for a course has ended, no refund is available, even if some lessons remain unwatched. The Access Period is stated in advance on the checkout page and the course detail page.

For monthly subscription products, the Access Period is each billing cycle (1 month). When the next payment is made or the subscription is canceled, the Access Period for the previous billing cycle is deemed to have ended.

For annual subscription (full-course) products, the Access Period is 1 year from the payment date.

No refunds are issued after the Access Period ends, even if there are unwatched lessons.

7. Refund Examples

0 of 24 paid lessons watched	Refund of 24/24, or 100%, of the amount paid
2 watched	Refund of 22/24 of the amount paid
5 watched	Refund of 19/24 of the amount paid
10 watched	Refund of 14/24 of the amount paid
15 watched	Refund of 9/24 of the amount paid
19 watched	Refund of 5/24 of the amount paid
24 watched	No refund

8. Refunds for Package Products

Package products follow the same principle. The per-lesson price is calculated based on the paid lessons included in the package, and the cost of the lessons watched is deducted from the refund.

Free OT and similar videos are excluded from the lesson count used for refunds, and playing a video counts as having watched it.
Example: If a package contains 50 paid lessons in total and the member has watched 10, 40/50 of the amount paid is refunded

9. Other Refund Information

Refunds are calculated starting from the day after you state your intent to request a refund.
Any portion of the refund amount under ₩10 is rounded down.
When grounds for a refund arise, the refund will be approved within 3 business days.
Refunds are issued within 5 business days of approval. Refunds may be delayed depending on the payment processor (PG) and the card issuer.
One month is calculated in accordance with Article 160 of the Korean Civil Act (Calculation by Calendar).

Regardless of the actual number of days, if classes start on September 7, one month runs through October 6. However, if classes start on January 31, one month runs through February 28, the last day of that month.

10. Special Courses

Special courses include event courses, non-regular courses, and specially planned courses. Separate cancellation, change, and refund rules may apply to them, and the Company must announce these individually for each special course.

11. Refund Restrictions

If account or course sharing is detected, membership will be revoked and, as a rule, no refund will be given.
Amounts paid with coupons or points, and any amounts discounted for other reasons, are excluded from refunds. As a rule, refunds are prorated based on the actual amount paid, excluding any discounts.
No penalties or refund fees are charged, and the Company covers the payment processor’s refund fees.

12. Switching Refund-Eligible Courses and Refunds upon Account Termination

If you want to switch a refund-eligible course to a different course, a direct switch is not possible. You must either receive a refund under the same terms as a regular refund and then re-enroll, or contact Customer Support.
If a member’s account is terminated by the Company for violating applicable laws or these Terms, the refund rules in this Article do not apply.

13. Refund Method

When the Company refunds fees to a user, it will, as a rule, use the same payment method the user used to pay.
If a refund cannot be made using the same method, the Company will notify the user in advance of the reason and the alternative refund method.
Cancellation and refund requests can be submitted through the website or Channel Talk, and the Company will promptly send the member a confirmation after receiving the request.

Article 15 (Effects of Cancellation, Refunds, Etc.)

Upon receiving a refund request, the Company will approve the refund within 3 business days and return the payment within 5 business days.
For payments made by credit card, e-money, or similar methods, the Company will ask the payment provider to stop or cancel the charge.

Article 16 (Protection of Minors)

When a minor aged 14 to under 19 pays for a paid service, the Company states on the checkout screen that consent from a legal guardian is required.
If a minor purchases a paid service without a legal guardian’s consent, the minor or the legal guardian may cancel the contract.
If cancellation is requested under Paragraph 2 of this Article, the Company will refund the amount already paid.

Article 17 (Privacy Protection)

Users are responsible for protecting their own personal information, and the Company is not responsible for problems arising from a user’s carelessness.
As a rule, a user’s account must be used only by that user and may not be transferred or lent to third parties.

Other details on the processing of personal information are governed by the separate “Privacy Policy.”
