Your credit card payment information is only saved in your account if you explicitly take action to save it (see this help center article for more information on how to save billing details to your account).
We currently do not offer functionality that allows you to manage your account's saved credit card information.
If you would like to delete card information saved in your account, please email firstname.lastname@example.org. Upon receiving your email request, ARTA has 30 days to comply. We will notify you via email once your credit card information has been deleted.
