The Centers for Disease Control used cell phone tracking data to measure whether Americans were complying with lockdowns, possibly including the (unconstitutional) state travel quarantines.
A bombshell article in Vice magazine reveals just how aggressively the federal government tried to track Americans during 2020 and 2021.

The CDC even considered using the data to track “adherence to state-level policies to quarantine after arrival from another state” – a particularly problematic use, as the state quarantines were highly constitutionally suspect even without any federal support for them. It is not clear whether the CDC went ahead with that part of the tracking.
