Also identify any privacy practices mentioned: Browser Controls for "Do Not Track." Some browsers have incorporated "Do Not Track" (DNT) features that can send a signal to the websites you visit indicating you do not wish to be tracked. Because there is not yet a common understanding of how to interpret the DNT signal, Microsoft services do not currently respond to browser DNT signals. We continue to work with the online industry to define a common understanding of how to treat DNT signals. In the meantime, you can use the range of other tools we provide to control data collection and use, including the ability to opt out of receiving interest-based advertising from Microsoft as described above.'}, {'role': 'assistant', 'content': 'This clause is fair.
