Nevada quietly signed an agreement earlier this year with a company that collects location data from cellphones, allowing police to track a device virtually in real time — all without a warrant.
To clarify, i reread, and the article does say they are buying the data from Fog Data. I’ve read elsewhere that Fog Data logs location data from installed apps using location services. I don’t know if that’s the only method Fog Data uses. If it is, turning off location services should significantly impair this approach. Airplane mode would not, though it would probably prevent radio triangulation like you describe.
My comment was that there are a lot of ways that phones record location data, and no single countermeasure stops all of them. In addition to apps using location services, the phones themselves track you in a lot of different ways. For example iPhones continuously monitor and log location data even when the phone is off. They use BTLE mesh when other methods are unavailable.
This lawyer does a great job of explaining surveillance technologies and how to avoid them. In the case of Fog Data it works the same as LocateX, relying on the devices advertising ID. In short, deleting the advertising ID and limiting the location permissions of apps to “only while using the app” renders these particular tracking methods ineffective.
