No, it's not. You are not protected from a private company that owns ALPRs as part of the 4th amendment.

The government purchasing data from 3rd parties (the third-party doctrine) doesn't violate your 4th amendment rights against unreasonable searches and seizures. You voluntarily gave the data to a 3rd party and the 3rd party voluntarily sold that data to the government.

The carve out is really only for phone GPS data (cell tower connection logs) as specified in Carpenter v. United States.

So just like you're not protected from AT&T selling your call logs to the government, you're not protected from Flock selling access to their images of your car (at this time).
