        <\/p>\n

        Data processing, storage, or access changes<\/td>\n

        <\/p>\n

        		The retention period for eCDN analytics data is reduced from 360 days to 180 days, changing how long data is stored and accessible.<\/td>\n

        <\/tr>\n

        <\/p>\n

        Retention policies, holds, or deletion workflows<\/td>\n

        <\/p>\n

        		The change enforces a shorter system-level retention window, resulting in earlier automatic deletion of analytics data.<\/td>\n

        <\/tr>\n

        <\/p>\n

        Admin monitoring and compliance reporting<\/td>\n
