Introduction

Welcome

What this service does, in one paragraph.

This service lets you send email attachments securely and receive them the same way — no passwords, ever. When you send a file, it's removed from the email before it ever reaches an inbox, and the person you sent it to can only open it after proving who they are with a passkey (their device's fingerprint, face, or a security key).

How it works, in short

  1. You send an email with an attachment, exactly as you always have.
  2. The attachment is removed before the email reaches an inbox.
  3. The recipient gets a short notice instead, with a retrieval code.
  4. They register a passkey the first time — no password, ever.
  5. Every visit after that is a single tap to open what was sent to them.
