Google has been tracking some location data from Android users — even when location services are turned off.
Quartz found since January, Android devices have been collecting Cell ID codes and sending the information to Google. It happens even when a device has no SIM card and when GPS location services are disabled.
Google confirmed the practice when Quartz asked.
Before panic sets in, Mashable points out Cell ID codes are different than GPS location information. Put simply, Cell ID codes are used to identify cell towers, not the exact location of a device. A Google spokesperson said the data was "immediately discarded."
Still, there's concern about whether Cell ID codes could be used to roughly pinpoint a person's whereabouts — especially since the tower tracking can't be turned off.
A Google spokesperson said the company will stop collecting Cell IDs by the end of November.
