Staff-only. Customers you send links to don't need to sign in.
The message is encrypted in this browser before it leaves. We store only the ciphertext.
Copy this link and send it to your customer. It will stop working after the view count is reached or after it expires — whichever comes first.
The decryption key rides in the URL fragment (#...) — browsers do not send fragments to servers, so we cannot read it.
Decrypting in your browser...
The link has already been viewed, expired, or was never valid. Ask the sender for a new one.
