Generating Excel file from pivot table

I signed up for the demo of the pivot table. When I export the data to Excel it displays the following at the bottom:
This document was made with Webix library. http://webix.com

Will this also be present when I buy the Pivot table? If so, is it possible to remove it somehow?

Hi, by default library uses our share server for an export.

You can install export scripts on your server, in such case an exported file will not have any watermarks.

Excellent, thank you!
