"DHS uses Google Analytics measurement software to collect the information listed above. The data are automatically sent to Google's system and the system immediately aggregates the data. DHS also uses conversion pixels and tags as part of the Department's use of Google Tag Manager (part of the Google Analytics suite) to monitor advertising effectiveness. We may use the aggregated data to share with our partners and contractors to help improve visitor experiences."

Browsing data is automatically sent to Google's systems via Google Analytics and Google Tag Manager, including conversion pixels for ad tracking. Aggregated data may also be shared with unspecified partners and contractors.

"DHS also uses conversion pixels and tags as part of the Department's use of Google Tag Manager (part of the Google Analytics suite) to monitor advertising effectiveness. 3rd party software, modules, or add-ins being leveraged on DHS websites may or may not use persistent cookies or similar technology; however, no data collected in this manner is accessible, viewable, or retained by the federal government."

The site uses conversion pixels and Google Tag Manager to track advertising effectiveness, which enables cross-site tracking of users. Third-party add-ins may also use persistent cookies, with DHS disclaiming visibility into that data collection.

"The Department retains the data from Google Analytics, and Survey Monkey survey results only as long as required by law or needed to support the mission of the DHS websites. Electronic messages that are not records are deleted when no longer needed."

Retention periods are defined vaguely as 'as long as required by law or needed to support the mission,' with no specific timelines given for most collected data, leaving the retention duration effectively open-ended.
