GravityCerts does not store details of your payment method. We use industry leading secure payment gateways and processors that utilize verified tokens for passing around subscription purchase approvals. All pages where payment method details are requested are hosted directly by the payment processor. In this way, your credit card numbers and PayPal credentials are not stored by us, not exposed to any of our employees, and are not transmitted through our servers. All that is shown as part of your account is incomplete details, such as the first and last credit card numbers.
