I'll be honest with you - I wouldn't even know what to do with user data if I collected it. I'm not great at training neural networks or understanding how to augment training with additional data.

Basically, the _only_ special thing about freemusicdemixer is that it runs client-side, because I'm better at writing C++ for a pre-trained network than I am at training new neural networks. However, it's a cool advantage so I'll keep promoting it as the distinguisher of my "product" (since I didn't create or train the underlying neural network, I just consider it a clever WASM frontend).

The operational costs are precisely $0 since it's a static website (aside from the domain registry).
