OpenX has the largest independent ad exchange network for publishers and demand partners, while maintaining the highest quality marketplace standards. Learn more. OpenX is an ad-tech company; this policy only covers its website visitors and business partners (ad-exchange data is covered by a separate Ad Exchange Privacy Policy). Requests go through OpenX's Data Subject Request webform (linked from its Privacy Center) where you pick the "employee, applicant, or business partner" option, or by phone at (855) 231-3834; for ad tracking you can instead enable Global Privacy Control or select "Reject" in the site's Cookie Preference Center. The exact webform URL is not printed in the policy text, so start from the Privacy Center / policy page links.
