[{'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: If the user has given consent (see also Item 11), we may display targeted advertising in Wooga games and services, or we may place or arrange for a cookie (see Item 2 above) so that targeted advertising can be displayed in the user's browser. This might include advertising that could be of particular interest to the user in view of the game being played for instance, or its age group or where it lives. We mainly advertise our own games and services. If we ever advertise for a third party, we will not provide the advertiser with any personal data and IP addresses and device identifiers (such as MAC addresses) will be duly abbreviated. Device identifiers help to optimize the delivery of the advertisements. They are not collected or stored, but only accessed locally on the user's device and immediately converted to secure hashed-based identifiers so that they cannot be resolved back to the original device identifier."}, {'role': 'assistant', 'content': 'This clause is unfair.
