Refund Policy

Effective date: September 24, 2026

This English version is a translation provided for convenience only. The Korean version is the official, legally binding text, and it prevails in case of any conflict or difference in interpretation. Read the Korean version (한국어)

This page summarizes Article 9 (Withdrawal of Subscription and Refunds) and Article 8(5) (free rerun after a rejection) of the DUIRE Terms of Service. If they differ, the Terms of Service prevail.

Full refund

You request cancellation after payment and before the test starts (including while the app is being installed on devices)
The test could not start because installations fell short of the number of devices posted on the Service
The test cannot continue due to a failure of the Company's devices or accounts, and switching to other devices or accounts or extending the period does not resolve it

After the test has started

Once your App is installed on at least the posted number of devices and the test has started, provision of the Service is deemed to have begun, and withdrawal of subscription is restricted under Article 17(2) of the Korean Act on the Consumer Protection in Electronic Commerce, etc. We show this on the payment screen and ask you to confirm it before you pay.

However, if the Service is provided differently from what was displayed or advertised or from the terms of the contract, you may withdraw the subscription under Article 17(3) of the same Act.

Free rerun instead of a refund

If Google rejects your production access application, request it via Support within 30 days from the day the Test Period ended, and we will run the Test Period once more at no additional charge. If the App has already been deleted from our devices, we reinstall it.

The free rerun is available once per App. It is not provided if the application is rejected again after the rerun, or if the App could not be installed or launched for reasons attributable to you, as listed below.

No refund

The App could not be installed or launched for reasons attributable to you (for example, removing Tester Accounts from the tester list, pausing the track, deleting the App or making it private, removing the Republic of Korea from the countries/regions, or making the App paid)
Google rejects your production access application or takes action against your developer account or App (a rejected production access application is handled by the free rerun above)
We discontinue the Service or restrict your use because you violated the Terms of Service

How to request a refund

Request a refund via Support on the dashboard or by email at zaco.labs@gmail.com. We begin the refund to your original payment method within 3 business days from the day we confirm your request. When it reaches you depends on your payment method.

The refund conditions above are the same wherever you paid; only how the money comes back depends on where you paid.
