HealthEngine is a data product case, not just a health-sector case. The platform collected information in the course of helping people book appointments, then used parts of the user journey for insurance referral arrangements and public reviews. The legal problem was that users were not given the clear picture they needed.
For startups and marketplaces, the lesson is direct: consent flows, referral revenue, reviews and ratings are legal features. They need product design, plain-language copy and operational controls, not a privacy policy sitting alone in the footer.
