The problem
The moment you email a document, you lose control of it.
It lives in their inbox forever — you can't see if it's opened, fix a mistake, or take it back. That's not protection. That's hope.
What protection means
Protected isn't stored. It's controlled.
You stay in control
Send any document as a link you own — watch every open, update it in place, and take it back anytime. Drive and email can't do that.
It never goes out of date
leveair reads the expiry off every COI, license, and contract and warns you before it lapses — so you never send an expired file.
You collect what you need back
Request documents with one link and gather W-9s, COIs, and signed contracts in one place — logged with identity, never lost in a thread.

The documents you can't control are the ones that cost you.
A lapsed certificate loses the job; a contract you can't take back ends up in the wrong hands. Protection is the difference between looking buttoned-up and getting caught off guard.

Questions, answered
What does “business document protection” actually mean?+
Three things: you keep control of a document after you send it (watch it, update it, revoke it), it never silently goes out of date (we track every expiry), and you can collect documents back in one secure place. It's the protection a folder or an email can't give you.
Isn't my Google Drive already protecting my documents?+
Drive protects a file sitting still. The moment you email or share one, you lose control of it — you can't see if it was opened, you can't fix a mistake, and you can't take it back. leveair protects the document even after it leaves your hands.
What kinds of documents is this for?+
The documents that run a business and cost you when they go wrong: contracts, invoices, certificates of insurance (COIs), W-9s, licenses, and agreements.
Do the people I send to need an account?+
No. They open your link in their browser in one tap — no login, no app. For sensitive documents you can require a one-time email check.
