Function Health: sovereignty score and 8 European alternatives

Function Health is a membership service for preventive health insights based on extensive laboratory testing. Members have blood and urine tested, covering areas such as hormones and nutrients, and receive the results in an app with explanations, a clinician summary and a personalised plan for next steps. MRI and CT scans are available as optional add-ons. According to Function, sample collection takes place at Quest laboratory locations in the United States or at home through a licensed specialist. It is a service delivered through an app and web platform, not something to self-host.

Function Health is a US company headquartered in Austin, Texas. Its privacy policy states that the company is headquartered in the United States, may use service providers in other countries, and that personal information may be transferred to the United States or other locations. That policy does not mention the GDPR, and the service is aimed at the US market. The data concerned is health data, a special category of personal data, held by a company subject to US law.

Why digital sovereignty matters with Function Health

Function Health is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Function Health hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Function Health is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Function Health together with your other vendors and gives a total score, a heatmap and the main risk drivers.
