The Company entrusts certain processing tasks necessary to provide the Service. Entrusted processors handle personal data only under the Company's instructions.

B. Overseas Third-Party Provision — Store Refund Review Records
When a user requests a refund from the App Store or Google Play, that store may ask the Company for records showing whether the purchase was delivered and to what extent the currency was used. The Company provides the records described below only where the user has given separate consent and only upon a request from the store.

Refund review for App Store in-app purchases |
Payment identifier (transaction ID), a substitute account identifier, delivery status, the proportion of the currency consumed, account tenure, refund history, and other factual information necessary for the review |

* Notice on Refund Review Records
The Company provides factual records only in response to a store's request, and
does not provide directly identifying information such as your name, email address, or profile name.
Your account is represented by a substitute identifier rather than your original account identifier.
The final refund decision rests with each store; providing these records neither guarantees nor compels a denial.
The Company does not take any adverse measure against a user solely because the user requested a refund.

We use Unity LevelPlay for monetization. Third-party networks (AdMob, Unity Ads, AppLovin) may collect information. You may opt-out via your device settings (Android: Settings > Google > Ads / iOS: Settings > Privacy > Tracking).
