Credit card payement

I'm pretty sure you made this topic in the wrong section. You should've put this in the support section Yo.

Depends on what you mean. Only people who has your cc/debt numbers are the credit processor the store uses.

Register your bank account to what, exactly? If you mean to your Fakku account, no it doesn't stay on your account after a purchase, although what you've bought does under My Account > Library; it'll be opaque if you've bought it.

In fact I don't think you get the option for it to remember your card details. I could be wrong there though.

FAKKU does not interact with your bank directly. Transactions are made with credit or debit cards with a third party payment processor. Your credit card data is never stored by FAKKU.
