Hi!
Tobii SDK license agreement explicitly prohibits data collection.

So if you are going to collect or transfer gaze data you might need to get a separate license from Tobii Pro.

Talking about the gaze data. The data you get through Unity SDK is almost raw:

EyeXFramework is also getting deprecated very soon and will be replaced by Tobii Core SDK. Beta is available here:
