Also identify any privacy practices mentioned: 3.3 Your mobile device We may provide features that rely on the use of additional information on your mobile device or require access to certain services on your mobile device that will enhance your Spotify experience but are not required to use the Service. (In other words, information that falls in the second category described in the Introduction to this Policy.) For example, we might allow you to upload photos to your profile, connect with friends, or let you use voice commands to control the Service. Granting us access does not mean you are granting us unlimited access to that information or that we will access specific information without your permission. To the contrary, for each type of information listed in this section, before we access this information or these features of your mobile device, we will ask for your permission. If you provide such permission, we will collect the information for the specific purposes explained at the time we ask for your permission. You do not have to give us such permission in order to use Spotify, and acceptance of this Privacy Policy does not mean you have granted us permission to access this information."}, {'role': 'assistant', 'content': 'This clause is fair.
