Send sensitive documents, photos and secrets through a protected viewing link. The right person sees it, watermarked with their identity, on your time limit, with every action recorded. And you can pull it back at any moment.
A normal attachment is a copy you gave away forever. A SightSeal link is a viewing session you still own.
Upload a document or photos, or type a secret. Pick a protection level: expiry, viewing window, view-once, access code.
Share it by WhatsApp, SMS or email. The recipient opens it in the browser. Nothing to install, no account to make.
Their name and number are watermarked across every page. You see when they opened it, how long they viewed, and every blocked print, copy or capture attempt.
The link expires, burns after one view, or dies the second you press Revoke, even mid-viewing.
Nothing on earth stops a determined person photographing a screen. So every layer here is designed to make what they capture worthless, and attributable.
Viewers state who they are before anything is shown, and accept confidentiality terms. Optional 6-digit access code shared through a separate channel.
The viewer's name and number tiled across every page and baked into the rendered content itself. Any leaked capture names its source.
Only a small area under the finger or cursor is ever sharp. A screenshot, or a photo from a second phone, catches almost nothing.
Set a viewing window with a live countdown, or let the link burn after a single opening.
Download, print, copy and right-click are disabled. The view blurs instantly when the window loses focus. Attempts are recorded.
Freeze a session mid-view, or revoke it outright. Open sessions blur or end within seconds, wherever the viewer is.
Send an upload request and receive a passport, contract or signed page straight into your workspace. No attachment sitting in WhatsApp forever.
Every session is scored on what actually happened: blocked prints, copy attempts, developer tools, recording signals. Honest labels, never fake certainty.
We tell you exactly what each level can and cannot stop. Security products that promise the impossible are lying to you.
Frictionless. Just a link.
Capture-resistant, not capture-proof: deters and records, and watermarks make leaks traceable.
For material that justifies an install.
Our highest tier: the file never reaches the device.
Off-market packs, owner documents, unit numbers and exclusive pricing, sent to verified buyers only.
Candidate CVs, offers and salary details, without CVs floating around inboxes forever.
Term sheets, drafts and settlement figures with an audit trail of exactly who saw what.
Line-by-line hold-to-reveal secrets that burn after one view. Nothing left in the chat history.
Launch pricing. Early access, subject to change.
Browser-based viewing cannot make screenshots impossible. Nobody's can, whatever they claim. What SightSeal does is make capture difficult, make anything captured nearly worthless (blur, reveal strip, one line at a time), and make every view personally attributable through identity capture and watermarks.
True OS-level screenshot blocking arrives with the Protected App tier on supported devices. Until then, treat this as what it is: strong deterrence, tight control and full traceability, which is what actually stops leaks in practice.
Your first protected sends are free. It takes under a minute.
