Gichul Master Help and Support
Effective October 21, 2026
If you run into a problem, check the items below, and email us if it is not solved.
1. Questions are locked
Only the free sample questions are open in each subject. Buy a pass with the pass button at the top right of the home screen to open all questions.
2. I bought a pass but it is not applied
Make sure you are signed in with the same account you bought with, and tap Restore purchases on the pass screen. An internet connection is required. If it still does not work, email us with your purchase receipt.
3. Using the app offline
A purchased pass keeps working offline for 7 days after the app last confirmed it with the server. After that, connect to the internet once to confirm.
4. I want a refund
Refunds are handled by Apple. Request one at reportaproblem.apple.com. When a refund is approved, the pass is revoked automatically.
5. A question or answer looks wrong
Email us the year, subject, question number and what looks wrong. We will check it against the original material and fix it.
6. When contacting us
Include your device model, operating-system version, app version, and the steps to reproduce the issue.
