It is possible to set your status to appear invisible when using Google Chat in Gmail. While signed in as Invisible, you'll appear offline to your contacts. But you can still start a chat with any of your online contacts while you are in this status.
To go invisible, from the status drop-down menu in your chat list, select Invisible.
If you don't want a particular person to be able to see your online status, you can block that person. Once blocked, though, you won't be able to see their status, and you won't be able to communicate with them through chat.
Google Chat and other clients:
- If you set your status to invisible in Google Chat, then you'll appear offline to your contacts who are also using Google Chat or other chat apps.
- But if you are signed in to Chat as invisible in one location like Gmail, but signed in with an active status using another client, you will appear online to your contacts.
- When chatting with someone who is using Hangouts, please keep in mind that you can't appear invisible on Hangouts. When you set your Google Chat status to invisible, Hangouts users will see your profile picture without a green dot in their contact list, meaning that you may be idle or unavailable on your computer.
- If you are signed in to Hangouts, you won’t be able to set your status to invisible.
