The app is for senders on Windows. Recipients need only a browser. We'll write when your seat is ready.
They open it in their browser.
They use the Google or Microsoft sign-in they already have.
Nothing to text or read out separately.
Half the key travels with your envelope; we hold only the other half.
Your file goes as an attachment, or stays in your own Google Drive as a link.
Take access back at any time. A copy already opened can’t be recalled.
PDFs, Office documents, images, zip files.
Send it the way that suits the person.
Everything you’ve sent and who opened it, from any of your PCs.
Windows Hello (face, fingerprint or PIN) instead of a typed password.
Kept in your own Drive, so a new PC or a reset never locks you out.
Early access is open.
