. . .  e.g., Amazon's
Alexa microphones
are "always on"
even after you say
"Alexa off"

1. The mic is always on
2. You only turn on and off the actions
3. Amazon says they do not store your voices
4. But Amazon does store the date, time,
   and actions taken*, associated with your
   profile -- in order to feed their advertizing
   cash cow.
