Also identify any privacy practices mentioned: Google Analytics also automatically collects data including app sessions numbers, session lengths, screen visits, flow from screen to screen, and app acquisition data (where a user came from to install an app). Alongside data that is automatically collected by Google Analytics, we also collect our own anonymous data on our app usage through Google Analytics. This includes game settings chosen, game results and other general UI events. Taken together, this data allows us to improve our apps in many ways. For example, if a high proportion of users can\x92t beat level 1 in our game, we need to make it easier. Such data can also help us improve artwork in the game (by knowing what styles are most popular), or help us determine default option settings. We also collect data on which of our apps are installed, so that we have a better idea of which apps might be popular with users of another of our apps. We also track the effectiveness of our in-app cross promotions (promoting our own other apps)."}, {'role': 'assistant', 'content': 'This clause is fair. The privacy practices mentioned are: nan.'}]
