Frequently asked questions
How do I get my purchase back on a new device?
Install the app on a device signed in with the same Apple ID or Google account, pass the grown-up check, and tap Restore Purchase on the purchase screen. You won't be charged again.
How do I request a refund?
Payments are processed by Apple and Google, so refunds are requested through each store: reportaproblem.apple.com for the App Store, or Payments & subscriptions → Budget & history in the Google Play app. If you get stuck, email us and we'll walk you through it.
Where is progress saved? Does it move to a new device?
Progress is stored only on the device and is never sent to our servers. That means it isn't transferred if you delete the app or change devices. Purchases can always be restored.
Can I change the app's language?
The app supports Korean, English and Japanese and follows your device language. You can also set a per-app language in your device settings.
What if my child makes a purchase by accident?
The purchase screen opens only after a grown-up check. If an unwanted purchase still happens, request a refund from the store as described above. We also recommend Ask to Buy (Screen Time on iPhone) or Require authentication for purchases in Google Play.
