Google Nest is Alphabet/Google's smart-home hardware line (thermostats, cameras, speakers/displays), whose data practices are governed jointly by a Nest-specific privacy statement and Google's general Privacy Policy once a device is linked to a Google Account. Public record shows the company has disclosed broad data collection tied to the Google ecosystem, has faced a 2019 controversy over an undisclosed on-device microphone, credential-stuffing-driven camera hijacking incidents, and is a named product line in an ongoing 2026 Google Assistant class-action privacy settlement. Corporate ownership has shifted publicly and traceably from a standalone Nest Labs acquisition to a separate Alphabet subsidiary and finally into Google's core hardware division.

The Nest Privacy Statement for Nest Products and Services defines personal information broadly to include data such as name, email address or billing information, 'or other data that can be reasonably used to infer' identifying information, as disclosed on Nest's own legal page (policy active as of September 1, 2023).
Google acquired Nest Labs in 2014 for approximately $3.2 billion; following Alphabet's 2015 corporate restructuring, Nest operated for roughly three years as a separate subsidiary before being merged into Google's hardware division in February 2018, as reported by TechCrunch.
CNBC reported that Alphabet folded its standalone Nest smart-home division back into Google's hardware unit in 2018, ending Nest's status as a separate Alphabet company and placing it under the same division that produces Pixel phones and Google Home speakers.
The Nest Privacy Statement discloses that if a Nest device or service is used with a Google Account, the resulting data is handled under Google's general Privacy Policy rather than Nest-specific terms alone, integrating Nest device data into Google's broader account-linked data ecosystem.
After the 2019 disclosure that Nest Secure contained an undisclosed microphone, the Electronic Privacy Information Center sent a letter asking the FTC to bring an enforcement action against Google, including seeking divestment of Nest, as reported by Fortune.
Google and Alphabet agreed to a $68 million settlement of a class-action lawsuit alleging that Google Assistant recorded and collected users' conversations through unintended 'false accept' activations, with the settlement class covering purchasers of Google-made devices including Google Nest Hub and Nest Hub Max; Google denies the allegations and admits no fault.
In February 2019, following user discovery that the Nest Secure home security hub contained a microphone not listed on its published technical specifications, a Google spokesperson told TechCrunch that the omission was an error and the microphone should have been disclosed.
