Request account deletion
Use this page to request deletion of your My Mine (package com.mymine.my_mine) / PLAY account and related data. You can submit a request here without installing the app.
Request on the web
- Have your PLAY ID ready (the ID of at least 6 characters you created when signing up).
- Open an email using the button below, or send “PLAY account deletion request” and your ID to this address: cosmobyte@kakao.com
- We delete the account after verification. Requests are usually processed within a few business days.
Delete in the app
If the app is installed, you can also log in to PLAY and delete your account directly using “Delete account” in the hub.
Data that will be deleted
- PLAY account (ID, nickname, and sessions)
- Server-side account data linked to PLAY, including balances, predictions, and community data
Portfolio and widget caches stored only on your device can be removed by uninstalling the app or deleting them on the device. If some records may be retained on a limited basis to prevent abuse or meet legal obligations, this will be stated in the notice at that time.
