Also identify any privacy practices mentioned: Our Apps may periodically examine the contents of your device to determine the presence of other Backflip Apps on the device. The App will transmit the results of that examination to Backflip and our advertising service providers to be used in targeting advertisements to your device. For example, if you have PaperToss and Ninjump installed on your device, when you play PaperToss, we will not send you ads for Ninjump and will instead send you other more relevant ads. When you start or stop an App, it may display an ad and during gameplay, a rotating banner ad may be displayed."}, {'role': 'assistant', 'content': 'This clause is fair.
