Do Not Track (or just DNT) is a privacy preference you can set in most browsers.

We support Do Not Track because we think it’s really important that you have a simple way to control how your info is used. That’s why, in addition to giving you a number of ways to choose how Pinterest uses your data, we honour DNT as a signal for how you want us to use data we collect outside Pinterest.
