Hello,
Flash should only be needed for the KMC, i.e Kaltura Management Console. As it is written in Flash. We currently do not have an alternative to that, though I can say we are aware of it being an issue and are working on it.
For MediaSpace and player, no Flash is required.
As for data tracking, I assume you mean the Analytics in KMC? can you explain exactly which screen and field you are referring to?
