To delete a Brawl Stars account without a Supercell ID, start by opening the Brawl Stars app on your device. Tap the three horizontal lines at the top right corner to access the menu and select “Settings.” From the settings menu, go to “Help and Support.”
Next, tap the “Account” option at the top of the page. Here, you will find a chat icon. Tap the chat icon and choose “Request deletion of your personal data.”
After you have made the request, confirm by tapping “Delete my data” and then “I agree to delete my data” in the chat window. Your account will be deleted after a short period, usually within 30 days.
Make sure you are completely sure about your decision, as deleting your Brawl Stars account is irreversible and will result in the loss of all your game progress.
