Including these details makes a fix much faster:

Account and data deletion

To delete your account and its data, email the address above from the account you signed up with, stating the app name and that you want your account deleted. After verifying it's you, I delete the account and its data without delay and confirm by reply.

What gets deleted, and the few items retained where law requires it, is listed in each app's privacy policy.

Privacy policies are currently published in Korean only. If you need an English copy of any of them, email me and I'll send one.
