  • Collects impression and auction data for bid optimization
  • Shares user identifiers with third-party ad buyers through cookie syncing

Consent & Compliance

  • Category: Marketing
  • GDPR: Requires consent. Performs cross-site cookie syncing and shares user identifiers with advertising partners.
  • CCPA: Qualifies as sale/sharing of personal information through real-time bidding and user ID synchronization.
  • ePrivacy: Requires consent for advertising cookies and cross-domain user identification.

Should You Block This Without Consent?

Yes. OpenX is programmatic advertising infrastructure that performs real-time bidding and cross-site cookie syncing. It should be blocked until the user provides consent for marketing and advertising.

Is OpenX GDPR compliant?

OpenX typically loads marketing trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So OpenX can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads OpenX, not on OpenX itself.
