Do Not Track legislation protects Internet users' right to choose whether or not they want to be tracked by third-party websites. It has been called the online version of "Do Not Call".^[1] This type of legislation is supported by privacy advocates and opposed by advertisers and services that use tracking information to personalize web content.^[2] Do Not Track (DNT) is a formerly official HTTP header field, designed to allow internet users to opt-out of tracking by websites—which includes the collection of data regarding a user's activity across multiple distinct contexts, and the retention, use, or sharing of that data outside its context. Efforts to standardize Do Not Track by the World Wide Web Consortium did not reach their goal and ended in September 2018 due to insufficient deployment and support.
