“Queries that exceed 100,000 signals will result in the overage signals being dropped.”
Fog Reveal lets local police draw a box on a map and pull every phone that passed through it. Tag one device and it shows 90 days of where that person went. The cops buy the data from brokers instead of asking a judge. The only cap in the manual is 100,000 signals per query, and that is a server limit, not a civil liberties one.
