AcuityAds may also utilize health-related targeting data segments provided by third party data companies, but don’t consider any of those segments to be sensitive. We don’t currently use such third party data when serving ads to EU data subjects. Data Retention AcuityAds retains the web log data for a maximum of 180 days, although we generally don’t retain this data for EU data subjects for more than a few days. After 180 days, we aggregate the log data so that it does not identify any individual device and retain the aggregate data for up to three years.
