Zachary McCoy, a restaurant worker in Florida, received a surprising email from Google. Google’s legal support team was letting him know that the local police department demanded some of his Google account data. Unless he tried to block it in court, they would release the data in seven days.
Not knowing what he had done, but noticing a case number, he began to search for the information. He found there was a burglary of a woman’s home within a mile of his and his roommates’ house. Knowing he had nothing to do with this, he contacted his parents who in turn hired a lawyer for him.
Their lawyer found out that they were looking for a “geofence warrant,” which just sweeps up all Google data from all GPS, Bluetooth, Wi-Fi connections nearby.
It turns out that McCoy uses an app on his phone called RunKeeper to record his bike rides. He found he passed by the victim’s home a few times within one hour, which is actually part of his normal frequent loops he makes all the time.
Even if you are innocently using your apps with GPS that keep track of your activities, you may be in the wrong place at the wrong time.
