# Do Not Track

Do Not Track (DNT) is a formerly official [HTTP header field](https://en.wikipedia.org/wiki/List_of_HTTP_header_fields), designed to allow internet users to [opt-out](https://en.wikipedia.org/wiki/Opt-out) of [tracking](https://en.wikipedia.org/wiki/Web_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 data derived from that activity outside the context in which it occurred.
