Google Assistant will remember everything, forever, unless you tell it when to stop

5 min read


Google Home devices have a physical mute switch, but it shuts off the microphone completely. To use voice commands with your device but still control how much voice data Google Assistant holds onto, you’ll need to change a few settings.

Relying on Google Home ($99 at Walmart) to manage your digital life requires something of a trade off in regard to your privacy, but that doesn’t necessarily mean you have to give up all your secrets just to get your smart speaker to work for you. It’s quite possible, through a combination of security settings and responsible privacy practices, to minimize the amount and kind of data you share with Google, and yet still take advantage of the hands-free convenience Google Home affords. The key is to know which info your Google Home can live without and still work the way you want it to.

As tech companies like Google face tougher public scrutiny following a scourge of privacy breaches in recent years, including evidence revealed last month that Google had been covertly supplying third-party advertisers with Google users’ personal data, many consumers are shying away from services that ask for too much of their information. In response, many tech companies — Google included — are becoming more transparent with their data practices by establishing portals where customers can access, delete and limit the data gathered about them.

If you love your Google Home, but want to limit the voice recordings, location information and other personal data that it keeps, these are the settings that you’ll need to adjust to fine-tune your privacy controls.

First, look up everything Google Assistant has on you

First, you’ll want to navigate to the Settings page that details all the information Google has been keeping on you.

1. Open your Google Home app.

2. Tap your personal icon (the little silhouette in a circle) in the lower right corner.

3. Under the Google Assistant heading, tap More settings.

4. Select You from the menu bar at the top.

5. Tap Your data in the Assistant.

Here you can scroll as far back as your record goes through every piece of information Google Assistant has been keeping about you. You can delete items one at a time by tapping the trash can icon beside each item, or you can follow the next set of steps to delete all of it.


Every interaction you have with Google Home is logged, including audio recordings of your voice commands, unless you tell Google Assistant not to.


Delete some or all of your private data

Google Assistant saves audio recordings of every voice command Google Home has ever heard (including false triggers), which helps the software to understand your voice and execute future commands better, but isn’t critical to the device’s operation. To delete that and all other data, starting from the Your data in the Assistant screen:

1. On the Your data in the Assistant page, under Your Assistant activity tap My Activity.

2. To the right of the search bar at the top of the page, tap the icon of three stacked dots.

3. Tap Delete activity by.

4. If you want to start over with a clean slate, tap All time. Otherwise, you can choose to delete all data collected in the Last hour, Last day or create a Custom range, say, from the day you started using Google Home until last month.

5. The app will ask you to confirm that you would like to delete your Google Assistant Activity for the specified period. Tap Delete to confirm.

6. The app will indicate, “Deletion complete.” In the lower right corner, tap Got it to return to the main Google Assistant Activity page.

Choose how often your data will be deleted

If you don’t mind letting Google Assistant remember your recent interactions with it, you can set the data to be deleted automatically after either three or 18 months. From the main Google Assistant Activity page:

1. Scroll down to Keeping activity until you delete it manually and tap Choose to delete automatically.

2. Change the setting to either 18 months or three months and tap Next.

3. When app asks you to confirm the change, scroll to the bottom of the page and tap Confirm.

4. Tap Got it to return to the main Google Assistant Activity page. 


Google Nest Hub also has a physical mute switch, however the Google Nest Hub Max, which has a webcam, does not have a physical shutter to cover the camera.

For the most extreme privacy option, pause all activity

Instead of regular purges, you can set Google Assistant to no longer keep logs of your data at all, but that may cause some hiccups with how well Google Assistant functions. If your privacy is of the utmost importance to you and you’re willing to deal with a few glitches from time to time, from the main Google Assistant Activity page:

1. Scroll down to Web & App Activity is on and tap Change setting.

3. Turn off the toggle beside Web & App Activity.

4. A screen will pop up, warning you that “pausing Web & App Activity may limit or disable more personalized experiences across Google services.” At the bottom of that screen, press Pause to stop Google from logging your activity. Note that changing this setting does not delete any of your personal data from Google, it only stops Google Assistant from recording more data going forward.

After you press Pause, you’ll be returned to the main Google Assistant Activity page.


Smart speakers aren’t the only gadgets paying attention to us — Sony’s Aibo robotic dog is just one of many smart devices on the market that listen, watch and remember.

That’s it — now you don’t have to declare open season on your private life or your personal data in order to enjoy your Google Home smart speaker or hub. This may be especially important if you’re concerned about Google restarting the human-powered quality assurance program it suspended in August in which reviewers listened to recordings collected from many of the over 3.2 million Google Home devices in the wild. 

Not to mention, smart speakers are just the beginning: nowadays robot dogs record your face and voice, Amazon uses human reviewers to troubleshoot security camera problems and Facebook admits to letting employees listen in on your video calls.
