Identity-bound document sharing for regulated industries

Know exactly who opened it.
Not just that it was opened.

Share documents with identity-locked access and complete data control. Every view creates a verifiable access record—who, when, device, and location—suitable for legal and compliance use. Forwarded links fail automatically. For added assurance, files can remain in your own cloud storage, not ours. Optional intent verification enables viewers to signal genuine interest via a small payment.

The Problem

You know it was opened. But by whom?

Email read receipts tell you a link was clicked. But they can't tell you who actually viewed the document. Was it your client, their assistant, or someone the link was forwarded to?

Anyone can forward the link Your confidential document ends up with unverified parties
No verified identity record "I never saw it" is impossible to disprove in court
Compliance gaps When regulators ask who accessed what—you can't prove it
No legal standing Generic access logs don't hold up as proof of delivery
How It Works

Identity-bound access in 30 seconds

Lock any document to a verified recipient. Every access creates an auditable identity record. Forwarded links simply don't work.

1

Upload your document

Drop any file—PDFs, contracts, statements, images. Encrypted and secured immediately.

2

Lock to a verified recipient

Bind the link to a specific person—via email verification or government ID check. Optionally require intent verification payment to signal serious interest. If they forward the link, it won't open.

3

Send the link anywhere

Email, Slack, SMS—doesn't matter. Only the verified recipient can access it.

4

Get verified proof of access

Every view generates a complete identity record: who opened it, when, from what device and location. See intent signals from viewers who paid to access. Court-ready documentation.

Verified Identity Records

Proof of access that holds up in court

Every access creates a complete identity record—not just that a link was clicked, but exactly who accessed it, verified and timestamped.

Verified Identity — email verification or government ID check
Cryptographic File Hash — SHA-256 fingerprint proves exact document version
Timestamp — exact date and time of access
Location & IP Hash — city, country, and anonymized IP fingerprint
Device — browser and operating system
Intent Signal — optional payment verification shows serious interest and commitment
Export — download as PDF or CSV for your records
