At Nest, we take your privacy seriously.

This document explains what kind of information Nest collects and stores, including Personally Identifiable Information (data that can be reasonably linked to a specific individual or household). To view our Web Site Privacy Policy, click here.

We pledge to:

  1. Be transparent about the different types of information we collect and how we use them.
  2. Ask your permission before sharing your Personally Identifiable Information with third parties for purposes other than to provide Nest’s services, and to do so only when we think they will provide you with a welcome additional service.
  3. Use best-in-class data security tools to keep your data safe and protect the Nest Learning Thermostat from unauthorized access.

By using this service, you agree to allow us to collect and process information as described below. If you have any questions, please contact us us at or call 855-4MY-NEST.

What information does the Nest Learning Thermostat collect?

The Nest Learning Thermostat collects:

  • Information input during setup
  • Environmental data from Nest’s sensors
  • Direct temperature adjustments to the device
  • Heating and cooling usage information
  • Technical information from the device

Information input during setup: When you install the Nest Learning Thermostat, you’ll be asked several questions about your schedule to help create an initial program of temperature settings. For example, we’ll ask questions like, “Is Nest located in a home or business?”. We’ll also ask for your postal or zip code so that Nest can retrieve weather information for your neighborhood. In addition, Nest pulls information directly from your heating and cooling (HVAC) system to learn its capabilities – such as if it has heating and cooling or is a heating-only system. Answering these questions helps us to set up an initial program that will keep you comfortable.

Environmental data from Nest’s sensors: We collect data from several sensors built into the Nest Learning Thermostat. These sensors collect data such as current temperature, humidity and ambient light in the room. They can also sense whether something in the room is moving. By recording this information, the Nest Learning Thermostat can make you comfortable when you are at home and save energy when you are away. For example, if Nest senses a light being switched on or that you’ve entered the room after an extended period of time, it can adjust the setting to a preferred temperature, based on an assumption that you’ve just woken up or returned home. Similarly, if the light goes off or no one is moving in the room, Nest may turn the temperature down sometimes to save you energy.

Direct temperature adjustments to the device: If you change the temperature on Nest, it records and feeds that information to the Nest algorithms to learn your desired comfort level under different situations.

Heating and cooling usage information: Every time your system turns on and off, Nest records the time and duration during which it was on in order to offer you features such as usage history.

Technical information from the device: In order to improve your experience over time and help troubleshoot any problem you may encounter with Nest, we record your Nest model and serial number, software version, and technical information such as battery charge level.

What additional information does Nest collect and store when a user connects their device to the internet?

To access your Nest Learning Thermostat over the Internet from a computer, a smartphone or a tablet, you will need to connect it to your Wi-Fi network. During setup, the Nest Learning Thermostat will ask for your Wi-Fi network name (SSID) and password to connect to the Internet. It will save this information on the device, along with your IP address, so that you can access it and control it from your computer, smartphone or tablet, and so that it can communicate with Nest servers and download software updates.

Once connected to your Wi-Fi network, your Nest Learning Thermostat regularly uploads to Nest cloud servers the data mentioned above (excluding your Wi-Fi password) to provide you with the service.

Additionally, when you create a Nest Account, we collect and store your email address. From that point forward, your email address is used for communications from Nest.

Like most Internet sites, we routinely record log entries (including information such as your IP address) and technical information (such as your browser type and version) when your browser, mobile device or Nest Learning Thermostat contacts our servers. These log files are used for troubleshooting and are stored on our cloud servers.

How does Nest use the information it collects?

We use this information to provide and improve the Nest Services, which will over time make you more comfortable and help you save energy. This includes information and recommendations about your energy use. We may use your email address to send you this information, or to ask you to participate in surveys about your Nest use. We use service providers to perform some of these functions. Those service providers are restricted from sharing your information for any other purpose.

We use industry-standard methods to keep this information safe and secure while transmitted over your home network and through the Internet to our cloud servers.

With whom does Nest share my information?

Under no circumstance do we share Personally Identifiable Information for any commercial or marketing purpose unrelated to the delivery of the Nest service without asking you first. Period.

Our service technicians and other Nest employees have supervised access to your information so they can answer your questions if you contact us for help and so they can monitor our servers for technical problems.

We may share your aggregated and anonymous information in a variety of ways, including to publish trends about energy use and conservation, to help utilities provide demand-response services and to generally improve our system. We’ve taken steps to ensure that the information cannot be linked back to you and we require our partners to keep all information in its anonymous form.

Your personal information may be collected, processed and stored by Nest or its service providers in the United States and other countries where our servers reside. As a result, your personal information may be subject to legal requirements, including lawful requirements to disclose personal information to government authorities, in those jurisdictions. We will disclose information to law enforcement, or to comply with other legal requests, only if provided with sufficient and appropriate legal process. 
 If you select an outside party for the purchase, installation, or service of your Nest device and share your personal information, we cannot control the collection, storage or sharing of information collected by that party. For example, if you bought your thermostat from a retailer, they may collect personal information as part of the transaction. Or the party that installed the device may retain information that you provided to them to assist them in servicing the device if needed. Always check the privacy policies for any company that collects your personal information.

How long does Nest save my personal information and how can I delete it?

Nest stores your Personally Identifiable Information on Nest’s cloud servers for as long as you remain a Nest customer in order to provide you with the service.

As described above, some information is stored directly on the Nest device. All information is encrypted and cannot easily be accessed. You can delete the information on the Nest device by resetting it to the defaults (using Reset in the Settings menu).

If you want to delete your Personally Identifiable Information from Nest’s servers, please call us at 855-4MY-NEST. Because of the way we maintain certain services, after your information is deleted, backup copies may linger for some time before they are deleted.

We hope this answers all of your questions. If you have any further questions, please contact us us at
