How to Send Confidential Documents Safely (Legal, Medical, Finance)

Sending sensitive paperwork? Here’s how to deliver confidential documents encrypted on your device, with files being removed from our storage when you close the room.

A settlement draft, a patient record, a signed financial statement — some documents can’t afford a wrong turn. Sending them the way you’d send a holiday photo is how leaks happen. Here’s a calmer, safer way to hand confidential files to the person who needs them.

The risk isn’t the send. It’s the copies.

A single document, sent once, isn’t dangerous on its own. The danger is the trail it leaves: the attachment in your sent folder, the copy in the recipient’s inbox, the version cached on a provider’s servers and rolled into backups for months. Every one of those is a place the document can leak from long after you’ve stopped thinking about it.

How to send a confidential document safely

  1. Open a private room. The document is scrambled in your browser before it goes anywhere.
  2. Drop the file in and share the short code with the recipient.
  3. Deliver that code through a separate channel from the document — say it on a call, or send it on a different app — so intercepting one doesn’t hand over both.
  4. They open it in any browser. When a room is closed, its files and room details are being removed from our storage. Our cloud provider may keep a recoverable copy for up to 7 days.

A quick checklist before you hit send

  • Is the file scrambled on your device before it is sent? It should be.
  • Is the file removed when the room is closed? Press Close to remove your files. Anyone with the room code can also close the room. When a room is closed, its files and room details are being removed from our storage. Our cloud provider may keep a recoverable copy for up to 7 days.
  • Are the file and its access code traveling the same channel? They shouldn’t.
  • The room closes when the timer ends, if a tab is still open.
