Revision of 2026-09-22

Current version

Added a clause that, for monthly subscriptions paid through Toss Payments (domestic payments), the unused part of the subscription's monthly units and AI chat messages does not carry over to the next billing period. Under the domestic payment provider's review rules for recurring payments, a subscription whose monthly allowance carries over cannot be operated as a recurring-payment product; the one-period carry-over on overseas-payment subscriptions (Dodo Payments, USD) is unchanged. Prepaid credits and AI chat message packs may now also be sold as one-off purchases through domestic payments (Toss Payments general payment); they do not appear on the pricing page until sales begin.

BeforeAfter
SKIMTUBE may provide monthly subscriptions, credit top-ups, AI chat message packs, subscription cancellation, and refunds for unused portions. Which products are sold depends on the payment axis: payments made in the Republic of Korea (Toss Payments, KRW) offer the monthly subscription only, while credit top-ups and AI chat message packs (prepaid chat messages) are offered only for overseas payments (Dodo Payments, USD).SKIMTUBE may provide monthly subscriptions, credit top-ups, AI chat message packs, subscription cancellation, and refunds for unused portions. Monthly subscriptions are sold through both payments made in the Republic of Korea (Toss Payments, KRW) and overseas payments (Dodo Payments, USD). Prepaid credits and AI chat message packs (prepaid chat messages) are sold as one-off purchases through both overseas payments (Dodo Payments, USD) and payments made in the Republic of Korea (Toss Payments general payment, KRW). Domestic one-off products appear on the pricing page as soon as they are ready for sale; until then, payments made in the Republic of Korea offer the monthly subscription only.
When you pay through Toss Payments (domestic payments), the units and AI chat messages remaining from a subscription's monthly allowance do not carry over. The operator would prefer to carry unused monthly allowance over for one more period regardless of payment method, but under the domestic payment provider's (Toss Payments) review rules for recurring payments, a subscription whose monthly allowance carries over into the next period cannot be operated as a recurring-payment product, so subscriptions paid through Toss Payments cannot offer carry-over. The monthly units and AI chat messages of a subscription paid through Toss Payments can therefore be used only within that billing period (from the payment date until just before the next payment date), and whatever remains lapses when the period ends. For overseas-payment subscriptions (Dodo Payments, USD), unused monthly units and AI chat messages carry over for one more period.
Credits and prepaid AI chat messages purchased through overseas payments are valid for one year from the date of purchase; any balance remaining after that period lapses. Units or AI chat messages granted separately by the company are valid for 30 days from the grant. The detailed terms follow the Refund & Cancellation Policy.Purchased credits and prepaid AI chat messages are valid for one year from the date of purchase regardless of payment method; any balance remaining after that period lapses.

Revision of 2026-08-27

Named Dodo Payments as the provider that sells and processes overseas payments as the Merchant of Record, and added a link to its Buyer Terms. Overseas payments are charged in US dollars (USD) only, prices are shown tax-exclusive, and the tax due for your country is added at checkout. The payment-dispute (chargeback) clause was rewritten to match the Refund & Cancellation Policy: while a dispute is open new payments are blocked; the block is lifted if the dispute is withdrawn or cancelled or the payment is confirmed valid, and if the dispute returns your money the unused balance that payment granted may be reclaimed and the block stays in place. The auto-renewal clause was clarified to match how each payment axis actually works: the email notice 7 days before the next charge applies to auto-renewing subscriptions paid in the Republic of Korea (Toss Payments, KRW), while overseas payments (USD) get no pre-renewal email — the next billing date is shown under Settings > Payments & Refunds and the amount and billing history in the Dodo Payments customer portal. The auto-renewal terms are displayed on the subscription screen, and signing up there constitutes your agreement to them.
