I think you're misunderstanding what it does. It's not sending your data to the cloud. It just lets you record a session when you press record. Also it's opensource too.
Hmm, maybe I jumped to the wrong conclusion. Is it like a delayed open-source release thing, like "sponsors get access to new releases before the open-source release"? I'm trying to understand how "subscribe for early access" coexists with "it's opensource".
