The Genetic Information Nondiscrimination Act (2008) prohibits discrimination based on genetic information in health insurance and employment. It does not cover life/disability/long-term-care insurance, and it doesn't directly regulate apps, but it sets the stakes: leaked genetic data can cause concrete discrimination harms.
It reinforces the "don't let it leak" posture and informs your consent and data-handling story.
Mentioning GINA signals domain awareness beyond pure engineering.
