Delete your Gichul Master account and data
Effective October 21, 2026
Gichul Master works without signing in, and account information is stored on our server only if you sign in. You can delete it as follows.
1. Delete in the app (recommended)
In Gichul Master, choose Account at the top right of the home screen → Delete account. Your account and linked server data are deleted immediately. Passes of a deleted account cannot be recovered.
2. If you cannot open the app
Email dhalska2@gmail.com with the sign-in method (Apple or Google) and the app name. After verifying it is you, we delete the data within 7 business days and let you know.
3. Data on your device
Study records stored only on your device are removed when you delete the app.
4. What is deleted
Your sign-in account and server data linked to it. Purchase records are kept, unlinked from the account, for the period required by law for refunds and bookkeeping, then deleted. Payment history in the App Store is managed by Apple.
