The ad-tech cookie web: a comprehensive snapshot of rivals' tracking data

The Register compiles a sweeping inventory of third-party ad-tech vendors (TCF and others), detailing each vendor's cookie usage, durations, and data collection practices. The list shows cookie lifetimes ranging from days to multiple years, and data collected including IP addresses, device identifiers, location data, user profiles, and authentication-derived identifiers. It notes whether vendors use other storage, and whether they rely on legitimate interests or consent, with several vendors not using cookies or using alternative storage. The piece underscores how pervasive and varied online tracking is across the ad ecosystem.

App Store apps leak user data to global ad-tech networks

A report shows a large swath of apps in the App Store transmit users’ data to a sprawling array of advertising and tracking vendors. Collected data include IP addresses, device identifiers, probabilistic IDs, location (precise and non-precise), browsing and interaction data, and user profiles, with many vendors using cookies for extended periods (months to years) or other storage. Consent models vary, some vendors claim legitimate interest while others state they don’t use cookies, and privacy policies differ across providers. The result is data flowing from millions of users to numerous ad-tech networks, underscoring privacy concerns about cross-app data sharing and the transparency of storage and consent practices.
