CCPA Opt Out

Last Updated: December 21, 2022

Opt out of sale/share for California residents

Our Privacy Policy describes the personal information that MediaMath uses to provide you with targeted advertising (also defined as “cross-context behavioral advertising”. When advertising involves the sale/share of your personal information under the CCPA, you receive ads and offers that are more likely to be useful to you.

Opting out of the sale/share of your personal information by MediaMath will also opt out you out of targeted advertising. Opting out will limit the personal information that MediaMath collects about you, and how we use that personal information. We will still use your personal information to serve you basic or contextual ads without the sale/share of any of your personal information under the CCPA. We will not target ads that are based on your interests to your browsers or devices.
