Appreciate the vote of confidence! And definitely hear the concerns re: data control. We're of the opinion that it's much easier to have a trusted vendor securely handle the system, keep it up-to-date, fix issues with some SLA, etc. and prioritize that part of the user experience. Your data is always yours to export, port, delete, whenever you want it. And should something catastrophic happen, we'd make sure that we give you enough resources/guidance to make sure you don't lose any of your hard-built intelligence.
How does this relate to your privacy policy? Will you train on or sell the data that you host? Or inferences about it?
