This app cannot identify individuals in any way. However, it uses an advertising system that optimizes ads based on your device information, so you may see ads targeted at you. This happens not only in this app but in other apps as well.
We are truly sorry that you saw an offensive ad. We ask our advertising partners to prevent offensive ads, and we will request that the ad in question be stopped immediately. We're sorry for the trouble, but could you send us a screenshot of the ad using "Contact us" in the upper right? Thank you very much. Please note that depending on the content of the ad, we may not be able to fulfill your request.
