From the menu in the upper right corner of the screen, select "Edit Profile," and then proceed with the withdrawal process from the "Withdrawal" menu displayed on the left side of the following screen.
You cannot reverse your withdrawal after it has been completed.
Tournaments you have created so far will not be deleted, but you will no longer be able to change the settings unless there are other organizers. If you wish to keep them, please add other players as organizers before withdrawing. Records of tournaments you have participated in (scores, handicaps, etc.) will remain on the tournament screen, but your name will be hidden.
If you registered by linking your account with other services, you can also unlink those services. For details, please refer to the following page.
