RocketHub does NOT store any credit card numbers, not even the last 4 digits of your credit card. Therefore, your data is safe on our platform.
The only payment information we have access to is a token linked to your credit card number provided by our merchant processor (Stripe or PayPal). This is how your payment information auto-populates in your cart on the RocketHub site.
If you want to change your payment method, just enter your new information in the "Payment Method" field at checkout. Because we don't store your information, you have the ability to easily update the card every time you pay.
