We can accept a PayPal payments for the lifetime account ($300 USD). If you want to purchase a lifetime account, send $300 USD to email@example.com and send an email to firstname.lastname@example.org to let us know that you have done so. We will then unlock your lifetime account. If you do not email us, we will not know that you made a payment.
For the monthly or yearly plan we don't have any PayPal integration yet.
If you must have Marvin and card payments or the lifetime account is not an option, reach out to email@example.com and we can probably make an exception for a yearly payment via PayPal.
