Platform and theme does FPD work with ?

Hello,

This product appears to be useful, however before I go ahead :

Does it function properly out of the box on nginx servers ?

Which theme does it work best with, out of the box ?

Does it work with Wordpress themes ?

Does it work with Woocommerce ?

Is it GDPR compliant ?

If you could be so kind as to  answer all of these questions, I can arrange my project accordingly and it would not be necessary to ask for a quick refund.
