Within Teamwork Chat, your profile status will change between online, away, and offline, depending on your activity with the app.

Online: If you are active then your profile image will be displayed with a green icon. 
Away: If you have been inactive for four minutes we will automatically mark your profile as 'Away' and your profile image will be displayed with an amber icon with a clock image on it:
Offline: If you sign out of chat you will be marked as offline and neither a green or amber icon will be displayed.
Note: The desktop app will keep you online if you're actively working on your computer (any click, keypress, tap).

If you are using the web/browser version, activity is only detected in the browser tab, which may lead you to being marked away along with receiving push notifications to the Teamwork Chat mobile app.
