When you hit send, your message is locked on your device before it ever touches the network. Only the person you sent it to holds the key that opens it.
That means the servers relaying your message can't read it — and neither can we. Delivery receipts, typing indicators, and message content are all protected in transit.
This post walks through the journey of a single message, the checks along the way, and why "we can't read your messages" is a design decision, not a promise.
