Google Home privacy settings cover separate things: audio saved to your Google Account, activity across Google services, and whether your home is occupied. Turning off audio saving does not delete recordings already stored, while turning off presence sensing can affect automations that detect arrivals and departures. The distinction matters because each control changes a different kind of data or feature.
Three controls, three different scopes
Google’s privacy controls are split between Google Account settings and Google Home’s home-presence settings. The table maps each one to the information it covers and the practical effect of changing it.
| Setting | What it affects | What changing it can mean |
| Voice and Audio Activity | Eligible Assistant audio saved to your Google Account | It is off unless you enable it. Turning it off does not delete audio already saved. |
| Web & App Activity | Eligible activity across Google sites, apps and services, including Assistant interactions | Turning it off reduces activity-based personalization. Automatic deletion applies to all Web & App Activity, not just audio. |
| Home presence sensing | Signals used to determine whether the home is occupied | Turning it off can stop presence-dependent automations from detecting arrivals or departures automatically. You can still start automations manually. |
Voice and audio: turning off saving does not erase old recordings
Google says Voice and Audio Activity is off unless you switch it on. Saving eligible Assistant audio also requires Web & App Activity to be on. The audio setting applies to the Google Account wherever you use Assistant, including a Google Home speaker. Google’s account help explains the audio setting and its limits.
If you turn the audio setting off, recordings already saved to your account remain there until you delete them separately. Automatic deletion is another control: Google says it applies to all Web & App Activity, rather than just voice recordings. Google Assistant Help lists retention choices of 3, 18 or 36 months, and says Google may delete some audio sooner. Google’s activity-deletion help describes the broader deletion controls.
Google says saved audio is used to improve audio-recognition technology and related services. Separately, the text of Assistant interactions may inform ad personalization, depending on account settings. These are different data types and uses.
Web & App Activity affects more than Google Home
Web & App Activity is a Google Account setting that can cover activity across multiple Google services, including Assistant. It is not a switch for audio alone. Disabling it can reduce activity-based personalization, but Google says Assistant can still handle basic tasks such as answering web questions, providing local information, playing media and setting reminders. Some personalized responses or features may be reduced. Google explains what Assistant can do with these activity settings off.
Home presence sensing is separate from Location History
Google Home presence sensing helps determine whether someone is home or away. Google says it can use phone geofence crossings, home Wi-Fi connections and signals from eligible home devices. A geofence is a virtual boundary around a place; here, the feature concerns whether a phone is inside the home area, not a person’s travel everywhere else. Google distinguishes this setting from Google Account Location History. Google’s Home help describes presence signals and their data controls.
Google says presence history is kept for 60 days and can also be deleted manually by eligible home members. If you turn off presence sensing, automations that rely on presence may no longer detect household members arriving or leaving. Manual automation starts remain possible.
What happens to audio while a speaker waits?
Google says Assistant-enabled devices process short audio snippets while waiting for an activation phrase. When the device does not detect an activation, those snippets are not sent to or saved by Google. Google also says unintended activations can happen, including when a sound resembles an activation phrase. Google’s device privacy help describes standby audio and unintended activations.
Where to review the controls
Google lists Voice and Audio Activity under Google Account settings, within Data & privacy, History settings and Web & App Activity. The Home app’s presence control is under Home settings, Home features and Presence sensing. Google says some account settings are being updated, so menu labels may differ. Check the account activity controls separately from the Home presence setting, especially if your routines depend on automatically detecting arrivals or departures.
