Outbrain is a web advertising platform that displays boxes of links, known as chumboxes to pages within websites. Outbrain (now operating under the Teads brand) offers a self-service opt-out toggle on this privacy policy page plus a self-serve "Interest Profile" portal where you can opt out of personalized ads, delete your user profile, or access your data. Note the opt-out is cookie-based and device/browser-specific, so it must be redone on each browser/device and after clearing cookies; app tracking must be turned off in your device settings, and US residents can also email ob-privacy@teads.com or call 1-866-I-OPT-OUT (service code 253#).
