Now, that's what ALL of the folks say except for Google
EXCEPT, that is exactly what Google does - just what the rest of them do... don't spread the paranoia:
Is Google Home recording all my conversations?
No. Google Home listens in short (a few seconds) snippets for the hotword. Those snippets are deleted if the hotword is not detected, and none of that information leaves your device until the hotword is heard.
The
all use the recording of your searches for "learning purposes". I would have no doubt that Google keeps it longer and/or integrates it into their other products much more than Apple or Amazon... but at least at Google you can delete your recordings at any time you want. Not sure about Amazon (not saying you can't, but haven't seen an obvious place to do it). I would guess Apple is the best about not doing as much with it since their services are not as important / integrated.
But more to C4W's point, nothing in that article says a word about them providing any recordings or implying that data was stored, just that police requested it via warrant and some data was turned over (very well could just be your last actual searches which you can see yourself in the Alexa app so clearly they are stored).
