Did Flock Safety's August 2026 privacy safeguards address concerns about its camera network?

Flock Safety said its August 2026 changes would shorten default data retention and strengthen controls on police searches. The ACLU said most measures remain inadequate and questioned whether Evidence Mode could preserve too much data.

License-Plate Surveillance Privacy Law Enforcement

Overview

Flock CEO Garrett Langley announced a seven-day recommended default retention period, Evidence Mode for preserving data in active investigations, offense filters for interagency searches and additional auditing. Existing customers would keep their current retention periods, and some controls were scheduled for later rollout. ACLU privacy advocate Chad Marlow said the shorter default might help but warned that Evidence Mode could preserve too much data and that other controls had not been shown to prevent misuse. The broader question of whether networked plate-reader surveillance should exist is tracked separately.

Flock SafetyFlock Safety, in a company clarificationDirectly involvedSeptember 1, 2026
Before this statement
Flock posted this page on September 1, 2026, for private-sector customers, about the updates it announced on August 13.
"Flock's latest privacy, security, and accountability updates strengthen account protection while preserving private-sector customers' control over their data, sharing, and retention settings."
Defended or excused
Case context: Did Flock Safety's August 2026 privacy safeguards address concerns about its camera network?
Full statement and sources
Flock said its latest privacy, security and accountability updates strengthen account protection while preserving private-sector customers' control over their data, sharing and retention settings. It said its new seven-day retention default applies to new law-enforcement customers, while private-sector customers keep the retention terms established for their accounts, and that multi-factor authentication is now required for all users.
After the statement
The post said offense-type search filtering would reach private-sector customers later in the year.
What Flock's privacy and security updates mean for private-sector customersRetention section: seven-day default and contract terms; authentication, auditing and offense-filter sections.
Why this label?
The case asks whether Flock's August 2026 safeguards address concerns about its camera network. In a post to private-sector customers, Flock says its updates "strengthen account protection", which presents the safeguards as meeting those concerns. Defended or excused fits because Flock is arguing for its own measures. Challenged the characterization is the closest competing label; it loses because the post does not dispute anyone's description.
This label describes the statement's response within the context above.
