Data security and privacy on devices that work with Assistant

Google's Privacy Policy explains what information we collect; why we collect it; and how you can update, manage, export, and delete your information, including when you interact with the Google Assistant. Learn more about Assistant and your privacy where we explain how your audio data is handled when you interact with the Assistant using a Google connected home device, as well as the controls available to you. You can review and update your Google Account settings anytime to choose what you share with your Assistant.

Google Assistant is designed to wait in standby mode until it detects an activation, like when it hears "Hey Google." In standby mode, the device processes short snippets of audio (a few seconds) to detect an activation (such as "Hey Google"). If no activation is detected, then those audio snippets won't be sent or saved to Google. Once it detects an activation, Assistant exits standby mode and sends your request to Google servers. This can, for example, happen if there is a noise that sounds like "Hey Google," or an unintended manual activation.

The status indicator on your device lets you know when Google Assistant is activated. To help keep you in control, we're constantly working to make Assistant better at reducing unintended activation.

Google uses information you permit it to access, such as your device contacts or activity on Google sites and apps, to provide better, more helpful answers through the Google Assistant. Third party services may also share information with Google pursuant to their own privacy policies when you choose to use those services via Google services, including the Google Assistant.

Yes. Activity controls in your Google Account let you decide what data is saved and used across Google services. For example, if you have enabled the Web & App Activity setting, the Google Assistant and Home apps can use your search history to provide you with better, more helpful answers from the Google Assistant. The Google Home app asks you to provide your address during setup. If you choose not to do so, Google Home app will guess your approximate location based on your IP address and other signals in order to set alarms for the right time zone and provide you with relevant weather and traffic information.

If you have chosen to share information with Google then, subject to your settings, Google uses that information, along with your Google activity, to better assist you and personalize your experiences with Google services, including the Assistant. For example, if you ask, "When is my mom's birthday?" the Assistant answers your question using information from your Calendar. Or if you ask "Do I need an umbrella tomorrow?" the Assistant uses your current location to give you the most relevant answer.

You can delete your activity in My Activity manually, set up automatic deletion, or turn off Web & App Activity entirely, which will limit the personalized experience in the Google Assistant and other Google services. You can view and delete your activity with Google Assistant by visiting your Assistant Activity, which is accessible through the Google Home and Google Assistant apps and online at myactivity.google.com.

Please read the Google Privacy Policy, the Frequently Asked Questions on Privacy: Google Nest, and our commitment to privacy in the home to understand what data Google collects, why we collect it, and the settings and tools available to you to update, manage, export, and delete your information when you use our devices and services.

Google Assistant might activate when you didn't intend it to because it incorrectly detected that you wanted its help - for instance when there is a noise that sounds like "Hey Google," or you manually activate your device accidentally. If that happens, and your Web & App Activity is turned on, you can say, "Hey Google, that wasn't for you," and Assistant will delete what you said from My Activity. You can also review and delete your Assistant interactions in My Activity at any time. If Google Assistant activates when you didn't intend it to, and your Web & App Activity setting is disabled, your Assistant interaction will not be stored in My Activity. To better tailor Google Assistant to your environment, you can adjust how sensitive your Assistant is to activation phrases (like "Hey Google") through the Google Home app for smart speakers and smart displays.

You can activate Google Assistant in many ways. For example, on speakers and displays, you can say "Hey Google." You can also use Look and Talk or a quick phrase you've enabled on your Nest Hub Max, or press and hold down on the top of Google Home. The status indicator on your device, such as an on-screen indicator or flashing LEDs on top of your device, lets you know when Assistant is activated.

Google handles your data as described in the Google Privacy Policy. If you use our connected home devices and services, please also read Google's commitment to privacy in the home and the Frequently Asked Questions on Privacy: Google Nest, where we explain some limits Google has placed on how your data is handled. Our privacy on Google Assistant video explains how your Assistant audio data is handled when you interact with the Google Assistant, and how the Google Assistant protects your privacy and gives you transparency, choice and control.

You can always review your Google settings to control the ads you see, including opting out of ad personalization completely. Learn more about the Google Assistant and the choices available to you.

Google Assistant might activate when you didn't intend it to because it incorrectly detected that you wanted its help. For example, it might activate when there's a noise that sounds like "Hey Google" or a quick phrase you've enabled, an unintended manual activation, or, for Look and Talk, if you're looking directly at your Nest Hub Max while talking to someone else. You can learn more by reading about how Google Assistant protects your privacy and gives you transparency, choice and control.

Anyone who is near your Google speaker or display device can request information from it, and if you have given your device access to your calendars, Gmail or other personal information, people may be able to ask your device about that information, depending on your personal results settings and Voice Match settings. Google employees and trusted third parties can also access your conversation history in line with Google's Privacy Policy. Learn about guests and your Google connected home devices.

Here's how to delete your Google Account.

Never. We do not sell your personal information to anyone. There are some circumstances where we share information with third parties, which are listed in Google's Privacy Policy. For example, using a Google connected home device, if you request a service from a business like Uber, we will send information you've provided to that service to complete a booking or confirm a ride. In these cases, we will have previously asked you to give us permission to share that information with that service.

Please note that when you use third-party services with our connected home devices and services, their own terms and privacy policies will also govern your use of those services. Review those carefully as you use those other services. For example, to help you faster and more easily, a service might use information from its past interactions with you.

In addition, a service that recommends concerts in your area can remember your music preferences if you share them with that service, so you don't have to tell them each time. Learn more about how to choose which services remember you.

Before a service can see any of the information stored in your account (such as your email address, name, or contacts), it'll ask for your permission. We won't share personal information like your name, email, or address with a service without your permission. Please note that when you use third-party services with our connected home devices and services, their own terms and privacy policies will also govern your use of those services, so please be careful about who you choose to share information with.

For example, if you're using a service to find local plumbers, it may ask:

"In order to recommend a plumber nearby, I'll just need to get your street address from Google. Is that ok?"

You can accept or deny the request.

We don't share Assistant queries with Works with Google Assistant partners. Google transcribes what you say and sends the text, but not the audio, to the third-party partner.
