Oniai is a free friend-making chat application designed for Android users. After installing the app, users can easily create a profile and start making friends with people who share their interests and are in their neighborhood. However, before starting the application, users must read and agree to the Terms of Service and Privacy Policy, which are available on the developer's website.

It is important to note that Oniai has strict rules and regulations, including prohibiting the use of the app for individuals under 18 years old, part-time job recruitment, solicitation, and posting of content that violates public order and morals or suggests sexual content. Violating these rules can result in the deletion of posts and suspension of user accounts without prior notice.

Additionally, Oniai supports 24-hour monitoring, which ensures the security of the app. For any inquiries about the app, users can contact the developer through the in-app inquiry feature.
