Screenshot protection
Block the capture. Trace the leak.
Every page a viewer opens is burned with their name and a timestamp, server-side, into the file itself, so a leaked copy always points back to the person who shared it. On top of that, we block the copy, save, and print shortcuts and wipe the clipboard the moment Print Screen fires. No software can stop a phone camera, and we will not pretend otherwise. But with Docshark, a leaked page is never anonymous.
How it works
Arm the protection
Toggle screenshot protection on any share link, dataroom link, or signature envelope.
The viewer opens the link
Their name and a live timestamp are burned into every page. The copy, save, and print shortcuts stop working in their browser.
Attempts are traced
A Print Screen wipes the clipboard. Every capture attempt is recorded in the audit trail, and the burned watermark still names the reader.
Where teams reach for it
M&A datarooms
Diligence files go out to dozens of bidders. Every page they open is marked with their name, so a leak has a return address.
Fundraising decks
Your deck gets forwarded around a fund. The watermark means you always know whose copy traveled where.
Board packs
Sensitive board material stays in the room, with every screen marked to the director reading it.
HR and personnel files
Offer letters, reviews, and employee records carry the reader's identity on every page.
Try it
Watch the page push back.
Toggle screenshot protection on, then try to print or copy. The shortcut is blocked, and the attempt is logged.
Questions
Quick answers.
Can you stop a phone camera?
No, and neither can any other web app. The same goes for a screen recorder or a photo of the screen. The watermark is the deterrent there: every page carries the viewer's identity and a timestamp, so a leaked photo points back to the person who took it.
Does this work on mobile browsers?
Keyboard blocking and the watermark work on mobile. OS-level screenshot blocking varies by browser and OS, so the watermark is the persistent deterrent.
Where do capture attempts show up?
In the audit trail for the link, dataroom, or envelope. For signatures, the attempt is added to the certificate of completion itself.
