How serious people send serious documents.
The contract. The memo. The deck. Only the person you send it to can open it, it disappears when you decide, and you know the moment they've opened it.
Only they can open it.
Send it to a person, not an address. If a link ends up somewhere it shouldn't, one click cuts it off.
Gone when you say so.
Set the expiry when you send. When it's gone, it's gone - no archive, no backup.
You know the moment.
The instant they open and download, you know. Not "delivered" - opened.

What you get
Send in a minute
Drop a file, write a message, add a recipient. Only they can open it.
Inbox and Sent
Everything you've sent and received, in one place.
You'll know the moment.
The second they open and download, you're notified. If you ever need to prove it, there's a signed, timestamped record anyone can verify.
We can't stop the person you trust from misusing what you gave them. But we close every other door, and you'll always know exactly who had it and when.
