Instantgo offers you the possibility to hide your name when placing a call or chatting if you ever feel the need to speak with someone privately and confidentially.
In order to hide your name, simply go to the settings page and activate the field "When looking for help, do you want your name to appear?".
When this field gets activated, the person receiving your request for help will only see an image of lock as your profile picture and will get a "private" as your Instantgo username and name.
You can enable and disable that privacy feature whenever and as often as you like in your settings.
