Hey there,
my service is facing the public without user login being required.
Would I still be able to:

# present a merged PDF to a unique user (the one who just filled out the form)? (I guess by using <<user ID = current>>). Would that need to require cookies on the user end?

# add paypal payment (via the existing formidable pro add on) and send people after payment to the download page for their PDF.

Again, all this without making other people outside the curent session being able to view the data and without the need for the user to log in to enjoy this feature.

Thanks!
Felix
