PRIVACY & CHOICE
Core HealthKit analysis and the default lab import run on your iPhone. Apple’s on-device Foundation Models improve biomarker matching when available; the default import stays fully local without them. Cloud AI lab import is optional and sends only the pages you select after an explicit choice and consent. AI Chat and Deep Research send only the content and health context you choose for that feature. Optional Sign in with Apple can enable iCloud sync of supported app data. No account is required to get started.

NO SUBSCRIPTION
Optional premium features are available as one-time purchases.

LongevLab is not a medical device or medical software and does not replace professional medical advice.
