iSexyChat review
iSexyChat advertises free, ad-supported rooms for adults and lists AI Chat separately. The free rooms let visitors talk to other users without signing up.
A public room and a direct message follow different rules
The chat rules describe what belongs in rooms and what stays in private channels. They tell visitors to report an issue by messaging a channel operator directly. The site’s free-room offer has no membership fee or message charge.
What the operator can do with messages
The terms say that recipients can save messages. They also give the service permission to monitor, record and reuse messages from both rooms and private chats. That permission applies to guest messages as well. Just a Chat also offers guest rooms, and its privacy policy describes temporary logging for moderation or investigations.

Anabel’s take
I’d stay with a public room. I’d skip direct messages if I wanted a conversation I could control after sending it.
