How do we respond to 'Do not track' signals?

Do Not Track ("DNT") is a privacy preference that users can set in certain web browsers. DNT is a way for users to inform websites and services that they do not want certain information about their webpage visits collected over time and across websites or online services. We do not recognize or respond to browser-initiated DNT signals, as the Internet industry is currently still working toward defining exactly what DNT means, what it means to comply with DNT, and a common approach to responding to DNT.
