We’ve known for quite a while that Siri can record your every word. Always hunting for its cue, how else would it be able to detect that often-excited “Hey Siri”? It does use buffers that only activate the listening device if it thinks it hears the magic words. So despite some allegations, Siri is not sending every word you say to Apple, its employees, or the government. But once you turn on the trigger? Then, it’s a different story.
