Just to be clear, when you collect response in Formscentral they are initially stored in the response table. You can try this much out with a free account. With a paid account at any level you can export your responses out of the response table as filled PDF. Note that there is no batch function for this each one must be individually exported. If you only care about collecting filled forms you could consider using an email based PDF workflow. In this case you would author the form in Formscentral and then save it out as a PDF without a submit button. Then in an application such as Acrobat you'd add a Submit button that sends the filled PDF to the email of your choice.
