Service Credit Terms of Use

Service credits are service-use balances for store administrators to use Link-Win store-management functions.

When a store uses paid functions such as checkout processing with customer store point issuance, fixed LINE service notices, or reservation-related LINE notices, the prescribed amount of service credits is deducted from the store balance. A paid reservation-related LINE notice costs 5 credits; no credit is consumed when no message is sent or the sending result is a definite failure.

Service credits can be used only within Link-Win and cannot be redeemed for cash, transferred to third parties, sold, lent, or exchanged for other services. They cannot be used as electronic money, a prepaid card, funds transfer, payment collection, a means of purchasing third-party goods or services, or a tool for collecting end-customer payments.

Purchased service credits expire 180 days (6 months) after the purchase date.

Expired service credits are automatically invalidated and deducted from the balance. Expired service credits cannot be restored.

Service credits are consumed first from the balance with the earliest expiration date (FIFO: first in, first out).

Purchases cannot be canceled after completion. Due to the nature of digital services, returns and refunds are generally not accepted after purchase.

However, if a duplicate payment, mistaken purchase, or payment error is suspected, we will review the unused status and handle the matter individually. If the Service cannot be provided for an extended period or is terminated due to reasons attributable to the operator, paid and unused service credit balances will be handled individually for refund.

If a refund succeeds in Stripe or a card dispute is lost by the store side, service credits corresponding to the refunded or lost amount are withdrawn from unused balances. Any portion that cannot be withdrawn because credits were already used is shown as outstanding credits; the displayed available balance does not become negative, and paid functions are suspended. Later purchased credits or operator compensation credits are applied to the outstanding amount first.

Paid functions may be suspended while a refund or card dispute is pending to prevent duplicate use. If a refund fails or is canceled, or a dispute is won by the store side or closes as a warning, the suspension is released when no other outstanding amount or review item remains.

System-granted credits, campaign-granted credits, and service credits related to fraudulent use or Terms violations are not eligible for refund.
