Yes, I am conscious of the immense protections health and personal data need to be guarded under when stored together. I recognize that there are strict certifications companies get to handle such info and I don’t have those. This is another place my decision to make everything public actually shines in my opinion. If I allowed making things "private", it might give a false sense of security (and require convincing the user to entrust that I could maintain that) whereas right now I hope it is clear that you should anonymize anything you input. I do not collect any personally identifiable info other than email (which can be a burner). Even if/when I integrate payments, the user should be able to use something like privacy.com.

I'm not well versed on business structures, so I'm having a bit of trouble following your second point about b-corps with relation to freemium.

Wow, that is exactly a path I have been thinking of taking this from the start. Vaguely, I'm interested in integrating biomedical papers linked by the conditions, therapies, and causative effects they mention and allowing discussion on them. Some of the higher-quality APIs I've found with this info do charge, so I'd be especially interested to hear about the projects you work on and if their license allows for use.
