A cookie policy is a document that outlines how a website or app uses cookies and other tracking technologies, and how it protects user privacy. It typically includes information about the types of cookies that are used, the purposes for which they are used, and how long they are stored on the user's device.

A cookie policy may also include information about how the website or app obtains consent from users to use cookies, and how users can manage their cookie preferences. In some countries, laws and regulations require websites and apps to obtain consent from users before placing cookies on their devices.

Consent management platform (CMP) can be used to help websites and apps obtain consent from users, track the consent status of users, and manage cookie preferences.
