You delete your account from inside the StarBright app, on any phone signed into it.
When the countdown ends, everything StarBright keeps for you on its servers is removed:
The app then switches to a guest account. Charts and photos that were already on your phone are not touched; uninstall the app to remove them.
Records the app stores generate about purchases, which carry a transaction identifier but not your name or account, are kept as required for accounting.
Email support@starbrightapp.com from the address you signed up with and we will delete the account for you. We will confirm by email once it is done.
