My website sells PDFs and I would like individuals who purchase those PDFs to only view them on our website. I don't want them sent to the person who purchases it, but instead, only have access to something on my site where they can go to view what they've purchased. The material is view only, and they cannot download or print this material.
I've seen a lot of apps and comments about how to restrict certain areas of the website, but nothing yet that can do this. Any ideas?
