Do I need to have SSL for Stripe App?

Hi,

I have installed Stripe App with Payplan. My question is, do I need to have SSL enabled in my website if I am using your Stripe App? From Stripe doc I understand that I wont need to have SSL (although its recommended) since the credit card details doesn't hit my server but since the App is not using the Stripe's quick checkout and has its own credit card form in Payplan checkout, do I need to have SSL enabled? Can I use Stripe App without SSL?

Thanks,
Neel.
