Cancellation and Refund Policy
Last updated: 2026-10-26 · Effective: 2026-10-07 (2.1.1 bank transfer clause: 2026-11-25)
Notice of change · Posted September 30, 2026 · Takes effect October 7, 2026 With the end of Woon gifting, the Woon gift refund sentence has been removed and a content voucher sentence has been added (usable within 90 days of receipt · no refund, exchange or re-gifting) (1.1). Until the effective date (through October 6, 2026), the previous policy applies. Amended October 8, 2026 (effective immediately) · A link gift clause has been added to 1.1 (receive within 6 months · expires without return of Woon after that · cancel before receipt for a return of Woon). This clause covers a new feature and does not change existing terms, so it applies from October 8, 2026. Posted October 26, 2026 · Takes effect November 25, 2026 · A clause has been added stating that woon topped up by bank transfer is not refundable (2.1.1). As this change is unfavourable to users, it takes effect 30 days after posting; top-ups whose deposit is confirmed by November 24, 2026 follow the previous terms (2.1).
This policy follows the Korean Act on Consumer Protection in Electronic Commerce. Where this policy conflicts with the law, the law prevails.
1. Paid currency "woon"
Paid content is unlocked with woon, spent in units. Because woon is consumed piece by piece, it is divisible digital content, and unspent woon counts as content not yet delivered.
1.1 Validity period
- Woon purchased with payment is valid for 1 year (12 months) from the payment date.
- Woon added before the effective date of this clause (21 September 2026) is valid for one year from that date.
- We notify you by in-app notice or email 30 days before the validity period ends.
- Woon received for free (ad rewards, events) is not covered by this clause and follows the terms stated when it was granted.
- The usage period and the refund-eligible period of paid Woon are limited to within 1 year from the payment date. This 1 year is the maximum period; actual refunds follow the conditions for web payments — within 7 days of the payment date, for unspent Woon (Article 17 of the Korean E-Commerce Act).
- Web refunds are returned to the original payment method; the per-transaction top-up limit is KRW 100,000. Paid Woon cannot be transferred to other users.
- Gifts can only be sent as content vouchers; Woon is never transferred to other users. A voucher is purchased with the sender's Woon and can be used only for its content within 90 days of receipt. Vouchers cannot be refunded, exchanged for Woon or cash, or re-gifted. A voucher not used within 90 days expires, and the Woon is not returned.
- A gift sent by link, if cancelled by the sender before it is received, has the Woon spent returned. If no one receives it within 6 months of being sent, the gift expires and the Woon is not returned. A received voucher cannot be refunded, exchanged or re-gifted.
2. Refunds
2.1 Purchased on the web
| Window | Within 7 days of payment |
| Scope | Unspent woon only |
| Amount | Pro rata (e.g. 600 woon for ₩36,000 with 200 left → ₩12,000) |
| Method | Reversed to the original payment method (card payments are cancelled — the actual credit date depends on your card issuer's schedule) |
| Rounding | Any fraction of a won in the pro-rata amount is rounded up (in the customer's favour) |
| Bonus woon | Bonus woon attached to that payment is reclaimed in the same proportion as the woon refunded |
⚠️ Woon already spent is not refundable — that content has been delivered.
2.1.1 Topped up by bank transfer
- Woon topped up on the web by bank transfer is not refundable, including unspent woon.
- This applies to top-ups whose deposit is confirmed on or after November 25, 2026. Top-ups confirmed before then follow 2.1.
- Cancellation of payments by minors (3) and refunds if the service closes (5) still apply regardless of this clause.
2.2 Purchased in the app (App Store · Google Play)
Billing, cancellation and refunds follow each store's policy. Please contact the store directly. We do not hold your store payment details and cannot reverse those charges ourselves.
When the store issues a refund, the woon credited by that payment and its bonus woon are reclaimed. Woon you have already spent is also subject to reclaim; in that case the balance is shown as negative, and paid use may be restricted until the negative balance is cleared. If the store reverses the refund, the reclaimed woon is restored to you.
2.3 Woon received for free
Woon given through events, bonuses or coupons is not refundable.
3. Minors
A purchase made by someone under 19 without their legal guardian's consent may be cancelled (Korean Civil Act art. 5), regardless of the 7-day window above.
4. How to request
Use Settings → Contact in the app or web with your payment date and order number. We respond within 3 business days.
5. If the service closes
Remaining paid woon will be refunded as announced in the closure notice.
