Secure document sharing you can take back.
Send a contract, an invoice, a COI as a link you control. See who opens it, fix it without resending, and pull it back — even after they’ve opened it.

How protection works
Protected isn’t just stored — it’s controlled.
A document in a folder just sits there. A document in leveair stays under your control — you watch it, keep it current, and take it back, even after you send it.

Send invoices, proposals, and contracts as a controlled link — see the moment it's opened, update the file without resending, and pull access back anytime. No recipient login.

Frequently asked questions
How do I send sensitive documents securely instead of as an email attachment?+
Email attachments are the problem: the moment you hit send, your contract, invoice, or COI lives forever in their inbox, their backups, and anyone they forward it to — and you have no idea who opened it or how to get it back. leveair replaces the attachment with a link you control. Every open is logged, you can update the file in place, and one tap pulls access back — and when a document is sensitive, you can lock the link to specific people with a one-time email check.
How do I know if someone actually opened the document I sent?+
Every leveair link comes with a live activity feed. The second your recipient opens the link you see their email, the exact time, the device, and which document they viewed or downloaded. No more wondering if your documents arrived or got lost in spam — the log tells you the truth.
How do I take back access after I've already sent the link?+
One tap. The link goes dark instantly — even if they already opened or downloaded the document. The next time anyone tries the URL they get a 'no longer active' message. Useful the moment a project wraps, an engagement closes, or you realize it went to the wrong person.
Can the recipient forward the link to someone else?+
By default a link opens for anyone who has it, so you can share it as freely as you like. When a document is sensitive, restrict the link to specific people: each viewer verifies their email with a one-time code, and anyone else who tries it is blocked — so a forwarded link is useless to them. Either way, you can revoke access in one tap.
Do the people I send to need an account or a login to view the document?+
No. Your recipient opens the link in their browser and views or uploads in one tap — no account, no app, no login to create. That's the whole point: it's friction-free for the people you send to (clients, lawyers, landlords, vendors). For sensitive documents you can add a one-time email check before the link opens, but they still never create a password.
Can I also request or collect documents from people, not just send them?+
Yes. Send a single upload link asking for exactly what you need — a W-9, an ID, a COI — and the other person uploads it back with no login. You see what's arrived and what's still missing at a glance, and leveair sends the reminders, so you're not the one chasing people for documents.
What's included in the $29/month plan?+
One business account, unlimited team members, unlimited leveair links, vault storage, full live activity + audit logs, per-document expiry, one-tap revoke, and AI auto-detect that fills in document metadata automatically. 7-day free trial, no credit card to start, cancel anytime.
