Vuforia builtin Unity

Hi,

Is there anywhere I can find the licensing process for Vuforia in Unity? I guess it was in the terms and conditions but like anyone else, I just pressed Agreed.

Usually, when using free Vuforia, you get limitations and mostly a watermark. But I just built on my device and I don't see any watermark.

I see the ARCamera has a field for a key but is it needed or is the fee somehow taken care of by Unity in the license (dunno...)?

Before anyone starts answering, I'd prefer a link to the official license system so there is no quiproquo.

Second, is there a roadmap for Vuforia Fusion? I am looking for the current supported version of ARKit and ArCore. 

Are they actually included in there or do I need to add them? I saw a tutorial where it said ArCore needs to be manually added in plugins folder. 

Thanks

Lucas
