Last Updated: January 29, 2021

Opt out of sale for California residents

Our Privacy Policy describes the personal information that MediaMath uses to provide you with tailored advertising. When advertising involves the sale 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 of your personal information will also opt out you out of tailored 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 ads without the sale 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.
