Frequently Asked Questions
Which languages does ONE store operate in?
Korean is preferred, but English is accepted. If you created metadata for the Korean language, UDP will submit this one. Otherwise, the metadata for the English language will be the one submitted to ONE store.
Which countries does ONE store reach?
South Korea.
Does ONE store support premium (pay to download) games?
Yes.
What kind of devices can ONE store client support?
Almost all the Android devices released by Korean operators support the ONE store client. If needed, you can target specific devices. You can find a full list of supported devices in the ONE store Developer Center under “Apps > Register App > New APK”.
Do I have to set IAP prices in KRW?
Yes. Use the “Convert” function in UDP to generate prices in KRW. The last digit of the converted price will be rounded down (e.g., 12349 won will be 12340 won).
How does the ONE store rating system work?

The developer should provide a game age rating for each game using the simple automated survey provided by ONE store.

If the game is rated as Adult, additional approval from the GRAC (Game Rating and Administration Committee) is necessary. GRAC has a website in English where you can apply on your own, without needing any local legal person to represent you. You can also access this Google support page for resources on the GRAC certificate application.

What are ONE store’s comprehensive game metadata requirements?
Please refer to the ONE store Developer Center for details.
How do I access the ONE store developer console after I register via UDP?
You can access the ONE store Developer Center directly at any time.
What are the rules and requirements for my game on ONE store?

You may not register games that may violate the laws, rules, or regulations of South Korea. Adult-only games must be rated by the South Korean government. Please check with the Game Rating & Administration Committee (GRAC) for more details.

The Terms of Services of the ONE store Developer Center state that a developer must not infringe on another’s intellectual property rights. If a property owner reports that a product is being sold without their permission, ONE store will suspend all sales of that product immediately.

What data privacy law does ONE store follow?
According to the Personal Information Protection Act of South Korea, users need to agree to the collection, purpose and retention period of their personal information.
How do payouts work in ONE store?

Sales are calculated monthly starting the 1st of the month, and amounts are finalized by the 15th day of following month.

International sellers need to submit a payment request. You can request a payment when the total cumulative amount is more than 100,000 KRW; the form is available on the ONE store Developer Center from the 15th to the 25th of the month following the month for which payment is being requested. The payment is made at the end of that month.

For overseas developers, a Korean bank account is not necessary. However, to verify the bank account, you are required to send a copy of your bank account statement and your ONE store Developer Center ID to devhelper@onestore.co.kr.

Payments are in South Korean Won (KRW) only. You can find more details about payments here.
