Legal documents with chain of custody, built in.
Legal document sharing demands two things: control and proof. Control over who sees the document, what they can do with it, and when access ends. Proof of who accessed it, when, and from where — evidence that holds up in litigation. FileLink delivers both. Every document is streamed through a secure viewer with the recipient’s email and IP embedded as a dynamic watermark. If a screenshot leaks, you know exactly whose copy it was. Every access, every OTP verification, every attempt is logged with timestamp, IP, and device — a chain of custody you can export.
The problem today
NDAs shared as email attachments can be forwarded or copied freely
No way to prove who leaked a document if it ends up in the wrong hands
Email metadata is not sufficient as litigation-ready evidence
No chain of custody for sensitive legal documents
How it works
Upload
Single file or full folder with subfolders. Encrypted the moment it leaves your browser.
Set the rules
OTP required, NDA gate, dynamic watermark, download blocked, expiry timer — you decide.
Share the link
Send via email, WhatsApp, or SMS. No recipient account, no app, no install.
Track everything
Real-time open alerts plus per-page dwell analytics. Know exactly who engaged and how.
Revoke anytime
Instant or scheduled. Access ends immediately — even after the file has been viewed.
What you get with FileLink
Dynamic watermarking
Recipient email and IP are watermarked on every page. Leaks are traceable to the individual.
Custom NDA gate
Require recipients to accept a custom NDA before viewing. Acceptance is logged with a timestamp.
Litigation-ready logs
Every access logged with IP, device, location, and timestamp. Exportable for evidence.
No copies
Files are streamed, not downloaded. There is no local copy to leak or forward.
