Content Protection
Make casual copying hard and obvious. TNC FlipBook 3D layers watermarks, copy blocks, devtools detection, print guards, and source-path hiding so your content stays under your control.
No DRM is unbreakable
But every layer raises the cost of stealing. Most readers will read. The few who try to lift content will hit friction at every step.
Watermark
Diagonal repeating watermark across every page.
Copy block
Disable right-click, copy, drag-save.
Devtools detection
Hide content the moment Inspector opens.
Print guard
Block printing entirely, or print with a watermark.
Source-path hiding
PDF URL never appears in network or HTML.
Admin bypass
Editors skip restrictions while previewing.
