Maybe I'm missing the obvious, but where's the source? I don't see a link anywhere?
I'm part of the "privacy and security" demographic. The thing you've got to understand about us is that we've been burned before, many times, by closed source products that are allegedly local only, but are secretly snitching behind our backs.
Market penetration may be difficult until people can see the source. If you're looking for a business model to attach to this, I recommend holding the training data in reserve as your paid product, and open sourcing the platform.
I'm guessing there's not a large demographic of people who want privacy-focused software, but don't care if it's closed source.
