The Google Play app “Cool Head Warm Heart: Trading” and the website chwh.app use the same account (operated by CHWH studio). Deleting the account on either one deletes it for both, and it cannot be undone once deleted. You can delete your account on this page without installing the app or opening the game.
1. Deleting Directly on This Page
Signing in with the Google account you used in the game serves as verification of your identity.
- Press the Google sign-in button below and sign in with the Google account you used in the game.
- When you return to this page, check the account number of the account you signed in with, and type the indicated word in the confirmation box.
- Pressing “Delete account” deletes your account immediately. If more than 10 minutes have passed since you signed in, you must sign in again for security.
- Google sign-in may be blocked in browsers inside apps such as KakaoTalk or Instagram. In that case, please open this page in a browser such as Chrome or Safari.
Checking the Google account connection.
You cannot sign in on this page right now. Please open it again a little later, delete your account in the game, or request deletion by email.
Once you sign in, we will show you the account number of the account to be deleted.
Google sign-in failed. Please try again.
There is no game account created with this Google account, so there is no information to delete from the server. If you played the game with a different Google account, please sign in again with that account.
For security, you can only delete your account if you signed in recently. Sign in again, then delete it.
Account number
Your account information, the progress saved on the server, and the account progress saved on this device will all be deleted, and you will be signed out. This cannot be undone once deleted. Your Google account will not be deleted.
Deleting…
Could not delete your account. Check your connection and try again.
Your account has been deleted.
The account information and progress on the server have been deleted, and that account's progress remaining in this browser has also been erased. If you have any tabs with the game open in this browser, please close them.
A tab with the game is still open in this browser, so the progress copy in this browser has not been erased yet. It will be erased when you close the game tab.
2. Deleting in the Game
You can also delete your account yourself in the game. While signed in, press “Delete account” under the account number in the game menu and type “delete” in the confirmation box to delete it. If more than 10 minutes have passed since you signed in, for security you can delete it after signing in again. Deleting removes, all at once, the account information, game progress and save check records on the server and the sign-in sessions on all devices, and also erases that account's progress, plaza progress and game lesson records stored in this browser. Copies of that account's progress remaining on other devices or browsers are not erased remotely, so please delete the site data on those devices. Your Google account is not deleted, and if you sign in again with the same Google account, you start with a new account.
3. Requesting by Email If You Cannot Sign In
If you cannot sign in, for example because you have lost your Google account, please send an email with the subject “Account deletion request” to contact@chwh.app. We will process your request within 10 days of receiving it and let you know the result by reply.
Please include your account number. This is the number shown on the title screen or in the game menu while you are signed in. As the server does not store email addresses or names, we cannot locate your account without the account number.
To verify your identity, please also include the city where you last stayed. If it does not match the progress saved on the server, we will not delete the account and will ask you again.
Information That Remains After Deletion
- Deleted information may remain in backups used for server recovery for up to 7 days (under the current plan). In addition, to prepare for server failures, the Operator downloads the server database and keeps it on an encrypted storage device; only the 4 most recent copies are kept, and copies older than 28 days are destroyed. Deleted information may therefore remain in these copies for up to 28 days, and these copies are used only for data recovery.
- Access records (Cloudflare logs) are retained for 3 days under the current plan and are then deleted.
- Inquiry emails are retained for 1 year after they have been handled and are then destroyed. Where retention is required by law, they are retained for the period so required.
- Hashes made from the anonymous statistics ID are deleted when the server processes the next statistics signal after that day has passed. Daily merchant counts (totals) are kept as numbers that cannot identify any individual.
