This is a very valid concern because I used to own a Zeo headband that did a lot of the same stuff, and when the company went belly-up the cloud service disappeared, leaving all their customers with a useless bedtime fashion accessory.
Really encouraging to hear the developer's reply that the their APIs will be accessible over wifi and that they'll even be open-sourcing some of their stack. Wonder if they specifically learned from what happened with Zeo. I'll definitely consider this as a replacement.
Actually Zeo had a very nice serial connection and I never uploaded any of their data, pushing it in realtime to my HA system. But yeah, I cry a lot that they are gone, it's almost impossible now to get a headband replacement.
