If someone interacts with your Google connected home device via Google Assistant, and the device does not recognize their voice, their activity on the device (like things they ask Google Assistant) may be stored in your Google Account. As the device owner, you can access this activity at g.co/assistant/yourdata (the audio recordings of this activity are not stored in your Google Account). If you allow guests to use your device, be sure they understand that their activity on the device may be stored by Google in your Google Account and that you can view and delete that information.
Alternatively, you or your guests can say “Hey Google, turn on Guest Mode.” While the device is in Guest Mode, Google automatically deletes audio recordings and Google Assistant activity from the device owner’s account.
