A consent-management platform (CMP) is a tool that helps businesses manage and track user consent for the collection and use of personal data. CMPs are commonly used by websites and online services to comply with privacy laws, such as the General Data Protection Regulation (GDPR) in the European Union and the California Consumer Privacy Act (CCPA) in the United States.

A CMP typically includes a consent banner or pop-up window that is displayed to users when they visit a website or app. The banner or pop-up provides information about the types of personal data that will be collected, how it will be used, and to whom it will be disclosed. The user is then given the option to consent or decline to the collection and use of their personal data.

CMPs can help businesses ensure compliance with privacy laws by providing a clear and transparent process for obtaining user consent. They can also help businesses track and manage user preferences and track consent over time. In addition, CMPs can provide businesses with analytics and insights into user behavior and preferences, which can be used to improve the user experience and optimize marketing efforts.
