Google will use your data as described in the Google Privacy Policy when you use any Nest or Google service, subject to the limitations explained below. Learn about Google’s commitment to privacy in the home here. You can manage your Google Account information, privacy, and security to make Google work better for you at myaccount.google.com.

Here are some key details about how your Nest data will be managed if you migrate:

Audio recordings and video footage from your Nest camera and Nest Hello video doorbell

Google will use this data to provide and improve the camera features and services you agree to receive, and will not use this data for promotions or ad personalization. To review and delete your video history or your individual saved clips, follow the instructions here.

Sensor readings collected from environmental and activity sensors

Some of your Nest devices include sensors that detect information about your home’s environment and what’s happening in it, such as motion, whether or not someone is home, ambient light, temperature, and humidity. Google will not use sensor readings from your home environment for ad personalization. Google will use this data for other purposes as explained in the Google Privacy Policy, such as providing your Google services and experiences related to the connected home, improving and personalizing them and developing new ones, for maintaining safety and security, and for keeping you informed of relevant Google products, services, and updates. This data will not be available for you to review and delete in My Activity, and turning off your Google activity controls will not stop the collection or retention of this data for these more limited purposes, since these purposes relate to your core connected home devices and services experience. This data is deleted when you delete your account, subject to Google’s account deletion practices.

Google Assistant usage with Nest devices

When you use your Nest device with the Google Assistant or other Works with Assistant programs, such as to explicitly control your devices and services using voice commands via the Assistant or the Home app (“Hey Google, set my temperature to 70 degrees”), these Assistant interactions can be used to show you relevant ads. Learn more in this Help Center article, which explains how the Assistant uses your interactions for personalized services and ads. You can review and delete your past Assistant queries at myactivity.google.com.

Other device usage data

When you are not interacting with Google services like the Assistant, your Nest device usage data (for example, when you manually adjust your thermostat’s temperature settings) will not be used for ad personalization. Google will use this data for other purposes as explained in the Google Privacy Policy, such as providing your Google services and experiences related to the connected home, improving and personalizing them and developing new ones, for maintaining safety and security, and for keeping you informed of relevant Google products, services, and updates. This data will not be available for you to review and delete in My Activity, and turning off your Google activity controls will not stop the collection or retention of this data for these more limited purposes, since these purposes relate to your core connected home devices and services experience. This data is deleted when you delete your account, subject to Google’s account deletion practices.

Location data collected by the Nest app

Nest offers a Home/Away Assist feature that uses inputs from activity sensors in your Nest devices combined with your phone’s location (after you give permission) to automatically modify the behavior of your Nest devices when you leave or return home. Learn more about Home/Away Assist here. You can turn off use of your phone’s location to inform Home/Away Assist in the Nest app at any time.

If you migrate to a Google Account, your location established by the Location History setting in your Google Account is not used by Home/Away Assist, nor is your phone’s location data collected by the Nest app used to establish Location History in your Google Account.

In the future, as we integrate Nest and Google location services to provide new features, we’ll be transparent and give you controls to manage your connected home information.

Data collected from nest.com and its subdomains, including Nest’s online store

The data collected from you when you use the public websites available at nest.com, nest.com subdomains, or Nest’s online store (including payment information and transaction history) will be associated with your Google Account and handled for the purposes set out in the Google Privacy Policy. You can manage your Google settings to limit how Google uses this data.

Other data, such as basic device and technical data

Any other Nest data, such as basic device data like device name, type and attributes, and technical device data like device serial number; IP and MAC address; device hardware and software information; Wi-Fi, network connectivity and settings information; and battery, diagnostics, crash, and performance information; is handled for the purposes set out in the Google Privacy Policy, including to troubleshoot and make your connected home services and experiences better and more reliable. You can manage your Google settings to limit how Google uses this data.

We’re always working on new ways to improve how you experience Google services. We’ll keep you updated on new experiences and product integrations Google offers, and if we change how your information is used, we’ll be transparent and give you controls to manage your connected home information.
