Key Features

Every Security Tool in One Platform

Password Protection

Set a custom password that recipients must enter before viewing. Change it any time without altering the share link.

Email Verification

Require a one-time code sent to the viewer's email. Verify identity and log exactly who opened the document.

View Limits

Set maximum opens per link. Once reached, the link auto-deactivates — perfect for one-time access scenarios.

Expiration Date

Make links expire automatically on a specific date. Ideal for time-sensitive contracts, proposals, and offers.

Dynamic Watermark

Overlay viewer-specific watermarks with email, IP, and timestamp. Trace leaks and deter unauthorized sharing.

No-Download & No-Print

Disable download and print buttons. Recipients can view online but cannot save or print a local copy.

FenceView

Restrict the visible area to a small movable window. Makes full-page screenshots nearly impossible.

Audit Trail

Full access log with viewer email, IP, device, location, and timestamp. Get Telegram alerts on every open.
