No, OnAir can't track your system.
Events on e2m OnAir run on browser and hence none of your data or system info is downloaded nor stored.
An event on OnAir gets access to only your audio and video devices for a seamless audio-video digital experience. Other than these, nothing else is accessed or tracked.
In case you want further clarification on this, our team at firstname.lastname@example.org would be happy to help you. Get in touch.
