Private by design.
Your emails contain sensitive information. We never see it. The Bcc copy reaches us, we verify the sender, record the timestamp, and discard everything else.
You choose which conversations count. Nothing is collected unless you explicitly add the address — and you can access, export, or delete anything we hold, anytime.

Every email you send without a Bcc is a yesterday you can't prove.
