Article 16. Refunds and objections to fees
① The Company shall refund fees paid in error or in excess.
② Where a refund is attributable to the Member, the general rules are as follows. A paid service whose use or purchase is completed by a single use after payment is not refundable after that use. For a service lasting one month or less from payment, the amount remaining after deducting the charge for days used as of termination is refunded. This also applies to services billed monthly in one-month units. For a service lasting more than one month from payment, the refund excludes the amount for days used as of termination and 10% of the total remaining days of use. If termination is requested within seven days of the start of the paid service, only the amount corresponding to days used is deducted.
③ Notwithstanding paragraph 2, the full amount paid will be refunded in the following cases.
1. The Member has not used the Service after completing payment.
2. The Member cannot use the Service because of a Service failure or a cause attributable to the Company despite meeting its stated minimum technical requirements.
3. The purchased service has not been provided.
4. The service differs from its description or advertising, or there is a significant discrepancy.
5. A defect in the service makes normal use substantially impossible.
④ For a refund attributable to the Company, including the reason in paragraph 3(2) or suspension of the Service, the Company will refund the amount corresponding to the remaining days of paid use plus an additional 10% of that amount.
⑤ Members may object to fees within one month of learning of the reason and within three months of the date the reason arose.
⑥ If the Company restricts use or unilaterally terminates the agreement because a Member violates Article 13, no refund will be given.
⑦ A full refund will in principle be made through the payment method originally used. If that is impossible, or for a partial refund following early termination, the Company will use a separately specified method.
⑧ Refunds under this Article will be made within three business days from the date the refund obligation arises. Interest on delayed refunds is 11% per year. If the Member’s cooperation is required, no delay interest is paid for a delay attributable to that Member.
⑨ Refund costs are borne by the Member where the refund is attributable to the Member, and by the Company where it is attributable to the Company.
Article 17. Termination of the agreement
① Members may at any time delete their ID and withdraw through Member information management, following the Company’s procedure, to terminate the agreement.
② If a Member violates Article 13, the Company may unilaterally terminate the agreement and pursue civil or criminal liability for resulting damage to Service operation.
③ If a Member has no record of logging in to use the Service for one consecutive year, the Company may revoke membership.
④ A paid-service agreement is terminated by the Member’s application and the Company’s acceptance. Termination takes effect when accepted, and any refund due will be made under Article 16.
⑤ Where the individual terms of a paid service specify a different termination method or effect from paragraph 4, those individual terms apply.
⑥ On termination, all Posts registered to the Member’s own account are deleted. Posts copied and published by another Member or registered on a shared bulletin board are not deleted.
