United States that individuals have a reasonable expectation of privacy in their cellphone location data, meaning law enforcement must obtain a search warrant with probable cause before requesting geofence location data from tech companies like Google. The ruling does not ban geofence warrants outright but requires authorities to meet 4th Amendment standards. The decision resolves a circuit split and has broad implications for how police can use reverse location searches. Google has already begun storing location data on-device rather than servers to limit exposure to such warrants. ## Full article daily.dev links to this article rather than hosting it.
