As reported by CNET, Google will allow law enforcement to access data from its Nest products — or theoretically any other data you store with Google — without a warrant. PetaPixel reports: “If we reasonably believe that we can prevent someone from dying or from suffering serious physical harm, we may provide information to a government agency — for example, in the case of bomb threats, school shootings, kidnappings, suicide prevention, and missing person cases,” reads Google’s TOS page on government requests for user information. “We still consider these requests in light of applicable laws and our policies.” 

An unnamed Nest spokesperson did tell CNET that the company tries to give its users notice when it provides their data under these circumstances. Google “reserves the right” to make emergency disclosures to law enforcement even when there is no legal requirement to do so. “A provider like Google may disclose information to law enforcement without a subpoena or a warrant ‘if the provider, in good faith, believes that an emergency involving danger of death or serious physical injury to any person requires disclosure without delay of communications relating to the emergency,'” a Nest spokesperson tells CNET. 

While Amazon and Google have both said they would hand over a user’s data to law enforcement without a warrant, Arlo, Apple, Wyze, and Anker, owner of Eufy, all confirmed to CNET that they won’t give authorities access to a user’s smart home camera’s footage unless they’re shown a warrant or court order. These companies would be legally bound to provide data to the authorities if they were shown a legal document. But, unlike Google and Amazon, they will not otherwise share camera footage with law enforcement, even if they had an emergency request for data. Apple’s default setting for video cameras connected via Homekit is end-to-end encryption which means the company is unable to share user video at all. 
In an updated statement, a Google spokesperson clarified that they have never sent Nest data to authorities, “but it’s important that we reserve the right to do so.” 

They added: “To reiterate, and as we’ve specified in our privacy commitments, we will only share video footage and audio recordings with third-party apps and services that work with our devices if you or a member of your home explicitly gives us permission, and we’ll only ask for this permission in order to provide a helpful experience from an approved partner (such as a home security service provider).”
