Their website's privacy policy doesn't say anything about their product. It's also incorrect (they seem to have switched tracking providers without updating their privacy policy). I would quote the sections that are incorrect, but their terms and conditions forbid copying any content from their site. Their T&C also forbids me from linking to their page or terms.
I very much doubt that using this product as advertised is even legal under the GDPR. The company is French and health data, even pseudonymized, is strictly regulated. The "demo" doesn't feature any explicit consent at the very least.
It looks like they're making all privacy risks and concerns the doctors' problems. After all, they're the ones violating the law when they use this product.
