No one will be able to search for or find your content from outside the room, so you can talk about whatever you want.
You don't need to create a complex profile with personal information; just offer a nickname and an avatar and you're set.
The app is highly rated by hundreds of users, whom I imagine mostly have made the in-app purchases to make the pesky pop-up ads go away and/or to have the extra feature of being able to select the gender they will be anonymously matched up with.
Apart from gender selection, everything else is up to the app.
