Is it safe for Uncle not to ask real-name registration system out?

My uncle doesn't register his real name with this anonymous chat software, which is very safe.

Uncle is not a software, it needs user's real-name authentication to use, and the software will not disclose real-name information at will.

Uncle is an anonymous chat software, and real-name authentication is safe, but you should pay attention to protecting your personal information during the chat to prevent being cheated.
