As a hang glider, a collision with an aircraft could ruin your day. Because of the limited maneuverability with a hang glider, carrying a complete FLARM system would not be feasible. Even if you were alerted of an imminent collision, there would be little you could do. For this purpose, there is a special FLARM module for hang gliders. The module alerts other aircraft of your position, so they can keep their distance. The module works autonomously without needing your attention.
