Privacy question

first of all, i have disability that affect my typing so please be kind! i try my best!

i just find this site and like it so far! but because i struggle with write because of my disability, and also i just nervous about people read my story in general, i not want rp's i do with bots to be post public for others to see.

i google this to see if they private and get confusing answer. it say that there is option to make chats private - but i look and not find this option anywhere....

please understand only give suggestion or such for WEB version only! do not suggest me download for my phone and use that! it not convenient for me! i better with type on computer.

but where is option to make sure chat's private?
