Privacy advocates got access to Locate X, a phone tracking tool which multiple U.S. agencies have bought access to, and showed me and other journalists exactly what it was capable of. Tracking a phone from one state to another to an abortion clinic. Multiple places of worship. A school. Following a likely juror to a residence. And all of this tracking is possible without a warrant, and instead just a few clicks of a mouse.
The iPhone remote locator function still works when the phone is powered off. It doesn’t work when the battery is completely dead, but it does work when the phone is supposedly “powered off.” This is irrefutable proof that iPhones at least retain some of their functions even when you’ve “turned them off.”
This is where paranoia comes into play. That’s Apple’s information. Not anyone else’s. If you believe Apple is selling it to this company and ignoring the phone setting that enables it then use the faraday bag.
But this company is not getting that information directly. It gets your information from cell tower pings at best, and social media scraping at worst.
