Protecting your information
is our only job.
LookLock wraps every confidential share with a tailored non-disclosure agreement the recipient signs before page one unlocks — and a tamper-evident ledger of every view, every page, every minute they spend inside. If a share ever ends up in dispute, the proof is already sealed — you reconstruct nothing.
Five turns of the dial.
Most doc-share tools ask the recipient to promise. LookLock asks them to sign — and only opens the material once the signature clears. No back-and-forth attachments. No "please sign and return." One link, one gate, one ledger.
Describe the share
Drop in a PDF, add one line about what's inside, pick an industry and governing-law jurisdiction. Everything else is optional.
A tailored agreement, drafted
Built from a counsel-reviewed clause library and scoped to exactly what's shared — one-way or mutual, amended by counsel as needed or fully custom. Most used: one-way and mutual NDAs, NCAs, and IP assignments.
They sign — the vault opens
The recipient signs, the deck unlocks page-by-page, and the signed PDF lands in the audit panel before they reach page two.
Every view, locked. Every page, logged.
When you send a deck through LookLock, the audit panel becomes the record. Not a separate vendor system, not a screenshot — the actual chain of custody, attached to the share that produced it. Most shares end well and nobody opens it again. The one that goes sour is the reason it’s here: a signed agreement and a minute-by-minute ledger, ready the day you need to prove what happened.
Signed NDA, hashed and stored
A PDF of the executed agreement, with a SHA-256 over the rendered plaintext so you can prove later which exact words were agreed to. Downloadable from the audit panel.
Recorded session
Optional screen + camera capture of the recipient's view. Stored alongside the share. Honors browser consent rules and falls back gracefully when capture isn't possible.
Page-by-page ledger
Entry timestamp and dwell time for every page they reached, written in monospace so you can scan it like a flight recorder. Pauses, re-entries, and skipped pages all show up.
Chain of custody
Signer name, email, signing timestamp, salted IP-hash, and user-agent string — paired against the agreement hash so a third party can verify the signature without trusting us.
Adjacent tools, missing pieces.
Most teams have already tried something. Here's what LookLock does that the usual suspects don't.
Not DocSend.
Analytics tools tell you who viewed. They don't ask the viewer to sign anything. If the deck leaks, you have a view-count — not an enforceable agreement.
Not a Notion share.
A link with permissions is a permission, not a promise. No audit trail, no chain of custody, no signed document to point to if a roadmap shows up somewhere it shouldn't.
Not e-sign + email attachment.
Sending an NDA, waiting for the countersign, then emailing the PDF is three days of back-and-forth. LookLock collapses the whole flow into one link the recipient resolves in minutes.
Not a generic data room.
Data rooms are built for diligence — multi-doc, multi-party, permission matrices. LookLock is the single-link, single-NDA, single-deck case the data room is too heavy for.
Your first send is free.
One full send on us — tailored NDA gate, session capture, the complete audit ledger. Subscribe when the second doc is worth protecting too.
