Payments, Refunds & Cancellations

Effective date: December 1, 2026

We refund Paid Gems you have not spent yet. This page explains what we refund, how much and how, and which items cannot be cancelled. It explains Articles 20 and 21 of the Terms of Service in plain language. This is an English translation; if it differs from the Korean version, the Korean version prevails.

Bought with Gems: Revive Tickets, pass tiers, Parts Bundles, Raid entries, and Rainbow crate and kit bundles.

3. Cancellation (withdrawal)

You may cancel a paid purchase within 7 days of the purchase date (or the date it became available, if later) without any fee or penalty. However, the following cannot be cancelled:

If an item differs from its description or advertising, or is delivered differently from what was promised, you may cancel within 3 months of the date it became available, or within 30 days of the date you learned or could have learned of this.

4. How to get a refund

Within 48 hours of payment

You can request a refund directly from your Google Play order history (the Payments & subscriptions menu in the Google Play app, or the order history on play.google.com). Such requests are handled under Google's rules.

After 48 hours, or if Google Play did not handle it

Email Customer Support at aiplanetcontact@gmail.com with:

  1. your Member No. (Settings → Account in the game);
  2. your Google Play order number (the number starting with GPA in your receipt email);
  3. the date and item you bought; and
  4. why you want a refund.

After checking your payment and Gem records, we refund you through Google Play to your original payment method. We start the refund within 3 business days of confirming your request; the date the money actually arrives depends on Google Play and the payment provider.

5. How much is refunded

Gem packs

Refund = amount paid × (unused Paid Gems from that payment ÷ Paid Gems received from that payment)

Within 7 days of payment you get this full amount; after 7 days, this amount minus 10%.

Example (illustrative figures): if you paid ₩10,000, received 1,000 Paid Gems and 400 are left, you get ₩4,000 back within 7 days, or ₩3,600 after 7 days. Bonus Gems are not counted and are taken back.

Remove Ads · Season Pass Premium · Bundles

When it is our fault

If the refund is caused by our fault, for example an error prevented delivery or the item was delivered differently from its description, we refund in full with nothing deducted.

6. When a payment is cancelled or refunded

7. Cancelling a minor's payment

If a player under 19 paid without the consent of a legal guardian (such as a parent), the player or the guardian can request cancellation by emailing Customer Support. After checking, we refund the full amount and take back what was received from that payment.

8. If the Service ends

9. Before you delete your account

Deleting your account removes your remaining Gems, Remove Ads and Season Pass Premium permanently. If you need a refund, request it before you request deletion. You can cancel a deletion request within 7 days (see Account & Data Deletion).
