[{'role': 'user', 'content': "Analyze the following clause from a privacy policy and determine if it's fair or unfair. Also identify any privacy practices mentioned: Important Information About Platform Permissions Most mobile platforms (iOS, Android, etc.) have defined certain types of device data that apps cannot access without your consent. And these platforms have different permission systems for obtaining your consent. The iOS platform will alert you the first time the Uber app wants permission to access certain types of data and will let you consent (or not consent) to that request. Android devices will notify you of the permissions that the Uber app seeks before you first use the app, and your use of the app constitutes your consent. To learn about the platform-level permissions that the app seeks, please visit our new iOS Permissions page and Android Permissions page. Sometimes these permissions require more explanation than the platforms themselves provide, and the permissions we request will change over time, so we've created these pages to serve as authoritative and up-to-date resources for our users."}, {'role': 'assistant', 'content': 'This clause is fair.
