FAQ

Dynamic watermarking FAQs

What is dynamic watermarking?

Dynamic watermarking stamps each viewer's email, and optionally the date and time, across every page of your document as they read it. Because the mark is unique to the viewer, any screenshot or leak can be traced straight back to its source.

Does the watermark deter leaks?

Yes. When viewers can see their own email printed over confidential material, they're far less likely to share or screenshot it. If a page does leak, the watermark tells you exactly who was responsible.

Does watermarking work without downloads?

Yes. Plox documents are viewed in the browser, so the watermark is applied live to every page. You can also disable downloads entirely so the file never leaves your control.

Which plan includes dynamic watermarking?

Dynamic watermarking is included on the Team plan and above, alongside screenshot protection, email verification and allow/block lists.

What information appears in the watermark?

The watermark carries the viewer's verified email, and you can optionally include the date and time of viewing. Because each mark is tied to a specific person, every page becomes traceable to whoever opened it.

Is the watermark applied to every page?

Yes. The dynamic watermark is rendered live across every page of the document in the browser, so there is no unmarked page a viewer could capture or share cleanly.

Can I combine watermarking with screenshot protection?

Yes. On the Team plan, dynamic watermarking and screenshot protection work together, so even an attempted screen capture carries the viewer's email and is degraded by the protection.

Does dynamic watermarking slow down the viewer?

No. The watermark is applied as the document renders in the browser, so viewers open and read your file normally with no extra steps and no download required.

How does watermarking help with data room security?

In a Plox data room, dynamic watermarking marks every shared file with the viewer's identity, which discourages leaks of sensitive deal documents and gives you traceability across the whole room.

Can the viewer remove or hide the watermark?

No. The watermark is rendered into the document view itself rather than added as a separate layer, so viewers cannot turn it off, and disabling downloads means there is no clean file to strip it from.
