A helpful home is a private home.
Your home is a special place. You want to trust the things that you bring into your home. And we’re committed to earning that trust with devices and services designed to help create a home that takes care of the people inside it and the world around it.
Which devices and services do these commitments apply to?
Why do we make these commitments to you?
Technical specifications transparency
When our connected home devices include cameras, microphones or environmental or activity sensors that detect information about your home environment, we’ll list these hardware features in the device’s technical specifications – whether or not they’re enabled.
Published Sensors guide
We will clearly explain what types of information these sensors send to Google, as well as give examples of how we use that information in our Sensors guide, to help you understand their purpose better.
Responsible advertising practices
For all our connected home devices and services, we will keep your video footage, audio recordings and home environment sensor readings separate from advertising, and we won’t use this data for ad personalisation. When you interact with your Assistant, we may use those interactions to inform your interests for ad personalisation. For example, if you ask, 'Hey Google, what’s the weather like in Hawaii in July?' we may use the text of that voice interaction (but not the audio recording itself) to show you personalised ads. You can always review your Google settings to control the ads that you see, including opting out of ad personalisation completely. Learn more about Google Assistant and the choices available to you here.
Technical specifications transparency
Google Nest participates in the Google Vulnerability Reward Programme.
Why it matters
This industry practice provides monetary rewards and public recognition for external security researchers who disclose vulnerabilities to the Nest security team. We want responsible security researchers to examine our products and we pay monetary rewards only after the disclosed vulnerabilities are fixed. Through this programme, the Nest security team can learn about and address vulnerabilities before they can be exploited.
How does this make Nest devices more secure?
How else does Google find security vulnerabilities?
Google Account security
We help to keep your Google Account secure with tools and automatic protection, like suspicious activity detection, Security Check-Up and 2-Step Verification.
Why it matters
We help to keep your Google Account secure with:
- Suspicious activity detection sends you notifications whenever we detect unusual or potentially dangerous activity, such as suspicious sign-ins to your account.
- Security Check-Up helps you secure your account and manage your online security through personalised guidance.
- 2-Step Verification strengthens your account security by adding a second verification step when you sign in, like a prompt from a trusted device or the use of a physical security key.
What is suspicious activity?
How does 2-Step Verification protect my account?
I have a Nest account and use that to sign in to the Nest app. Why should I switch to a Google Account?
Automatic security updates
We provide automatic, critical security updates for Google Nest devices for at least five years starting when the device is first available on the US Google store..
Why it matters
We employ many layered defences to protect users; however, technology changes and new threats arise. So we commit to providing automatic software security updates that address critical issues known to Google Nest. We will publish a list of devices and how long we commit to providing updates for them.
How do I know if my device is getting updates?
What is outside the scope of security updates?
So that Google Nest devices run only the software that they’re supposed to, we verify software before it’s installed. All our devices released in 2019 and after use Verified Boot.
Why it matters
We take steps to help prevent malicious software from being installed on Google Nest devices. This helps to ensure that no one has access to your account or control of your devices without your permission.
How do you prevent malicious software from running on a device?
Your Google Account device activity page lists the Google Nest devices that are visible in your Google Home app.
Why it matters
All the devices that you’re signed into will appear in your Google Account device activity page. That way, you can make sure that your account is connected only to the devices that it should be.
How does a device connect to my Google Account?
What happens if I see a device that I don’t recognise in my account?
Cameras serve a variety of purposes in the home, such as capturing memories, connecting with loved ones and helping you feel secure. Devices like Nest Cam use video to help you keep an eye on your home and alert you when things happen, even when you’re not there.
For all our connected home devices with cameras, we commit to you:
Your camera sends video footage to Google only if you or someone in your home has explicitly turned the camera on or enabled a feature that needs it (such as Nest Cam monitoring). You can always turn the camera off.
When your camera is turned on and sending video footage to Google, we will provide a clear visual indicator (such as a green light on your device).
When video footage is stored with your Google Account (for example, via a subscription to Nest Aware), you can access, review and delete this footage at any time.
We will only share video footage with third-party apps and services that work with our devices if you or a member of your home explicitly gives us permission.
Where available, Nest Hub Max offers on-device camera sensing features that help you personalise and control your experiences based on what the camera sees, such as Face Match (which helps your device recognise you) and Quick Gestures (which helps you control your device). Once enabled, these on-device camera sensing features don’t send video or images from your Nest Hub Max to Google.
How can I review and delete my stored video footage?
Do Nest Hub Max’s camera sensing features ever send video or images from my home to Google?
Are there times when video footage is sent to Google servers without a visual indicator?
Microphones serve a variety of purposes in the home, such as letting you control devices throughout your home using just your voice, detecting unexpected activity in your home when you’re not there, and making a voice call using a smart speaker or display.
For all our connected home devices with microphones, we commit to you:
Your device will only send audio to Google if we detect that you or someone in your home is interacting with your Assistant (for example, by saying 'Hey Google'), or if you use a feature that needs it (for example, where available, sound alerts on Nest Cam or Nest Cam video recording with audio enabled). You can always turn the microphone off.
When your microphone is turned on and sending audio to Google, we will provide a clear visual indicator (such as flashing dots on top of your device or an on-screen indicator).
When audio recordings are stored with your Google Account (for example, the audio from your Nest Cam footage when you’ve subscribed to Nest Aware, where available), you can access, review and delete your recordings at any time.
We will only share audio recordings from your devices with third-party apps and services that work with our devices if you or a member of your home explicitly gives us permission.

Are my Assistant voice queries used to inform ad personalisation?
Are there times when audio recordings are sent to Google without a visual indicator?
Some of our 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 at home, ambient light, temperature and humidity. These sensors serve a variety of purposes, such as helping your home take better care of you – like when your Nest Learning Thermostat, where available, turns itself down when you’re away – and helping us make your devices and services better.
For all our connected home devices with these environmental and activity sensors, we commit to you:
We’ll help you understand how the sensor readings collected from your home environment are used in our devices and services. That’s why we’ve published this guide to sensors in our devices.
We will only share your device sensor data with third-party apps and services that work with our devices if you or a member of your home explicitly gives us permission.
Why does Google collect environmental and activity sensor data from my home, and how is it used?
Google Wifi devices, where available, are router systems that work with your modem and Internet Service Provider to create a whole-home Wi-Fi mesh network. These devices use data about your network performance (for example, network speed and bandwidth usage) to help provide and improve your Wi-Fi coverage and experience. It also allows you to see which devices are connected and how much bandwidth they use.
For Google Wifi devices, we commit to you:
Google Wifi devices do not track the websites that you visit, nor do they monitor the content of traffic on your Wi-Fi network.
We keep your Wi-Fi network performance data separate from advertising and don’t use it for ad personalisation.
We will only share your Wi-Fi network performance data from your Google Wifi devices with third-party apps and services that work with our connected home devices if you or a manager of your Wi-Fi network gives us permission.
