When Flock and the Boston Police Department began its contract for 156 days at no cost to the city from April 1, 2025 to Sept. 4, 2025, the "contract clearly noted that data sharing was to be disabled, and BPD confirmed with Flock that settings were 'off' for sharing," read the 2025 annual report slated to be released Monday, WBUR reported.

However, "within three days of initiating the Pilot, BPD became aware that other law enforcement agencies were able to access license plate and vehicle information," blaming an "error" by Flock, according to WBUR.
