django-dnt offers an easy way to pay attention to the DNT (Do Not Track) HTTP header. If users are sending DNT: 1, DoNotTrackMiddleware will set request.DNT = True, else it will set request.DNT = False.
Just add dnt.middleware.DoNotTrackMiddleware to your MIDDLEWARE_CLASSES (Django 1.9 and earlier) or MIDDLEWARE (Django 1.10 and later) and you're good to go.
