🛡 How is this 100% secure?

Think of it like this: We manufacture the lockbox, but you create the key. When you click "Create," your browser generates a random key and locks the message locally. We store the locked box, but the key is only ever shown to you (in the link). We physically cannot open your message because we never see the key.
