After logging in, navigate to the Settings - Profile page. Scroll down to the bottom of the page where you will find the "Delete My Account" button. Click on it and complete the verification process.
Deleting your Meshy account is a permanent action. All of your models, generation history, and associated data will be irrevocably erased. Take care to back up any necessary data before proceeding with this decision.
Please note: Meshy Support is unable to delete accounts at your request, so be sure to do it in your UI as shown above.
