Does this plugin require purchasers to login to the website?

I just found this plugin and trying to set up. This looks really nice.

I’m wondering if purchasers have to log in to the web site to complete a payment. I’ve seen a demo video of this plugin demonstrating to show a list of download links that the purchaser can access. That probably means that the user needs to log in to the site. That is very good feature but I’d like to also let them purchase products without logging in.

Thanks.
