I think this fairly short story explains geofence ruling better so do it.
Does say Google policy now is not sharing data except on customers devices
Justices say Constitution protects people's location history
The 6-3 decision ruled police need a warrant to get people's location data, even if it's shared with companies like Google and Apple.
https://www.politico.com/news/2026/06/29/supreme-court-location-data-ruling-00979929The Supreme Court ruled on Monday that people have an expectation of privacy from the government as their mobile devices track them throughout their daily activities, even when that information is shared with companies like Google and Apple.
The 6-3 decision in Chatrie v. United States extends Fourth Amendment protections to data that people hand over to tech companies, meaning police need a warrant to obtain it. Justices Samuel Alito, Amy Coney Barrett and Clarence Thomas dissented.
The Trump administration argued that users did not have an expectation of privacy after voluntarily sharing their location data with companies like Google.
“An individual has a reasonable expectation of privacy in records about his cell phone’s location, and police intrude on that constitutionally protected interest when they demand the information — even though for only a limited time, and from a third-party tech company,” Justice Elena Kagan wrote for the majority.
The case involves a 2019 bank robbery in Virginia, where police arrested Okello Chatrie after using a geofence warrant to locate all devices near the scene of the crime.
