We are not directly involved into the apps delivery, nor do we have any direct beneficial relationship with the developer and users. We are committed to providing a fair and direct app reviews platform for our users on both side, in order to provide more convenient and efficient platform services. During platform registration and use, we will not charge any fees. However, to cover the usual business spent, we cooperate with the third party ad services, such as: Google, etc.. So which means, once the website users click on the ads, we could get benefited from that. Thanks for your understanding.
