The log
Every knock on the door, written down.
Opens and blocked attempts land in the same log, with who and when. Nothing slips by quietly.
Secure send
A link you control, even after you send it.
Email attachments leave your hands forever. A Docshark link stays yours: set the rules before it leaves, watch every open, and turn it off any time.

How it works
1
Upload the document
PDF or Word. It becomes a managed link, not an attachment.
2
Set the rules
Password, expiry, allowed emails, download rules, watermark.
3
Send one link
Share it anywhere. Every open lands in your log from second one.
Try it
Flip the controls yourself.
Click the toggles to arm the link, then revoke it. This is the real control set.

Beyond the lock
The full force of the link.
Sending is half the story. The link keeps watching after it leaves: every knock logged, limits that enforce themselves, and a name on every session.

View limits
A link that knows when to stop.
Cap how many times a link can be opened. When the limit is reached, the door closes by itself.
Email verification
Proof of inbox before the first page.
Require viewers to verify their email before the document opens, so every session has a name.
Questions
Quick answers.
Do viewers need an account?+
No. They open the link in a browser. If you set a password or an email check, they pass it first.
What happens when I revoke a link?+
It stops working everywhere at once. Anyone who tries it after that is blocked, and the attempt shows in your log.
Can I see who was blocked?+
Yes. Denied opens are recorded with the email that tried, so you know who knocked.
Keep exploring
The rest of the envelope.
Get started
Send it. Prove it. Sign it.
One link from the first open to the final signature.
