You can simply set hidden values which will not be emailed to the customer like date, user ip, user agent, Joomla userid, Joomla username, server ip, server host and server url. You can also define a custom hidden value or use values from the URL (GET variables).
To use GET variables simply add the hidden value $_GET['variable'].
The form can be submitted to email addresses (TO, CC and BCC) including a CSV file containing all inputs. Also to the user as a copy (without attachment and hidden fields), as also as redirected to a new page as GET or POST data and optional as POST hidden in the background. This means you can process the data already in the background. Furthermore the data is stored in the Joomla database, too.
