(4) Coins are deducted at the time the User requests an analysis. If the analysis is not completed normally due to the Company's fault (server error, system failure, etc.), coins are not deducted.

(5) Dissatisfaction with the accuracy or quality of results after a normal analysis completion does not constitute grounds for coin refund. (Please refer to Article 15 regarding the limitations of AI technology.)

(6) The Company may change coin-related terms (unit price, package composition, etc.) for reasons such as service improvement, and such changes shall not affect coins purchased prior to the change.

Article 12 (Withdrawal and Refund)

(1) The Company provides free coins (20 coins) so that Users can sufficiently evaluate the suitability of the Service's functions before making a payment.

(2) If a coin package has been purchased, a withdrawal request may be submitted within 14 days from the payment date, and a full refund shall be provided only if no coins have been used.

(3) If one or more coins have been used, it shall be deemed that the provision of digital content has commenced, and the right of withdrawal shall be restricted in accordance with the Act on Consumer Protection in Electronic Commerce.

(4) No refund shall be provided after 14 days from the payment date, regardless of whether coins have been used.

(5) Notwithstanding Paragraphs 2 and 3, refunds shall be available in the following cases:

• If the Service is permanently discontinued due to the Company's fault (unused coins shall be refunded based on the purchase unit price)
• If other refund grounds stipulated by applicable laws are met

(6) Free coins (promotional coins) are not eligible for refund under any circumstances.

(7) Refunds are processed through the original payment method, and the processing period may take 7 to 14 business days depending on the payment method.

Upon cancellation, the User acknowledges that (i) unused coins are forfeited and non-refundable (except where refund requirements under Article 12 are met), and (ii) the User's access to the Service, including keys or passwords, shall be revoked.

(2) The Company may, in its sole discretion, with or without prior notice, suspend or terminate the User's keys, passwords, or access to the Service upon the occurrence of cause.

(3) Upon expiration or termination of this agreement, all licenses granted hereunder shall immediately terminate, and the User must permanently delete all data provided by the Company.
