Keith Collins for Quartz:
Since the beginning of 2017, Android phones have been collecting the addresses of nearby cellular towers—even when location services are disabled—and sending that data back to Google. The result is that Google, the unit of Alphabet behind Android, has access to data about individuals’ locations and their movements that go far beyond a reasonable consumer expectation of privacy.
Quartz observed the data collection occur and contacted Google, which confirmed the practice.
Explanation by Google:
“In January of this year, we began looking into using Cell ID codes as an additional signal to further improve the speed and performance of message delivery,” the Google spokesperson said in an email. “However, we never incorporated Cell ID into our network sync system, so that data was immediately discarded, and we updated it to no longer request Cell ID.”
Don’t be evil [and get caught]. ™
On a serious note, when location services are disabled, nothing better be using or logging my whereabouts. Furthermore, who is to say the data they collected was really discarded? Caveat emptor.
