Deleting your account removes your login, name, email address, API keys and your access to every store you manage. Your access ends as soon as you confirm, and the account is permanently removed after 30 days. Until then you can sign in again to keep it.
Records of ticket sales you processed and agreements you signed stay with the store, without your name attached, for as long as tax and audit rules require. Deleting your account does not close a store or affect its events, orders or customers.
