Our own statistics: every page view on apasmath.com, where visitors came from (other sites and the utm_ tags of an ad), and what they did. Sign-ups and purchases are read from the accounts and enrolments, through the accounts visitors signed in to, and credited to the source that first brought them. No IP address and no cookie are kept.
