Prevent saving / delete PDF from Server automaticly

Hey,

exporting the form to a PDF works very well.

Sending by email also works. Unfortunately, all PDFs are stored in a public folder on the server. Some of the data in the PDF is sensitive. Is it possible to prevent the PDF from being saved on the server?

The PDF should only be sent by email.

So far, I always have to manually delete the PDF from the server.

Thanks for any information.
