FAQ

Frequently asked questions

Does this addon work with any theme?
Yes. It works with any WordPress theme, since it builds on your existing TNC FlipBook or PDF Viewer setup.
Do I need the main plugin first?
Yes. Secure PDFs is an addon, so it requires TNC FlipBook Classic or the free TNC PDF Viewer to be installed and active.
Does it stop people from downloading my PDFs?
Yes. It keeps your documents view-only, blocks the download and save options, and prevents download-manager software from grabbing the files.
Can visitors still read the PDF normally?
Absolutely. Readers get the full viewing experience on your site — they just can’t download, copy, or redistribute the file.
Is it compatible with the latest WordPress version?
Yes. It’s tested and kept up to date with the latest WordPress core releases.
How do I get support?

Reach our support team any time through the Help Docs portal or the contact form in your account.

Can I upgrade my plan later?

Yes. You can upgrade to a higher site-count license at any time, and we’ll adjust the difference automatically.
