Our supercomputers check your PDF for total page count and then delete it.
More specifically, this is the hike your beautiful PDF will take:
1. You submit the form.
2. Our supercomputers grab the PDF and it is uploaded to a temporary location.
3. Then tiny page-counters, who work for jelly beans, count the pages.
4. The file is then trashed, hopefully for two points.
5. By the time the form submission is complete, the file has already been deleted.
