Although this application can not identify individuals at all, because it uses an advertisement system where advertisements are optimized based on customer's device information, advertisements are targeted to those who use it You may. This is a phenomenon that occurs not only in this application but also in other applications. If you would like to avoid such ad delivery as much as possible, open the "Settings" app on iPhone or iPad, tap "Privacy", tap "Ads" and turn on "Restrict tracking ads" .
Also, I'm sorry for those who displayed unpleasant advertisements. We are also asking advertisement companies not to make unpleasant advertisements, but we will make an urgent stop request to prevent unnecessary advertisements again. I'm very sorry to trouble you, but can you send it from the "FAQ / feedback" in the application with a screenshot of the advertisement? Thank you for your consideration. Moreover, please understand beforehand because it may be unable to respond to customer's request depending on the contents of advertisement.
