“Schedule my invisibility” is a feature that is only accessible to happn Premium users. In order to schedule your invisibility, all you have to do is go on the “My Preferences” menu from the “My account” or tap on “My happn Premium”, then on “Schedule my invisibility” and “Invisible mode scheduled”. This will allow you to choose the week days as well as the times during which you do not want to be visible to the other users. A banner will let you know whether the Invisible mode is activated or not at the bottom of your Timeline.
