Your health data stays on your device. The companion computes everything — daily logs, survey scores, your BioAge — locally in your browser. We do not upload, sell or share your personal health information. Ever.
Google and Firebase Authentication process your identity, sign-in events and session tokens. Your profile measurements, daily wellness logs, self-check results and BioAge history are stored separately for each Firebase user ID in this browser's local storage. Clearing browser data removes those health records.
The current companion does not upload individual or aggregated wellness records. Any future employer or institution reporting program would require a separate, explicit opt-in and would never expose individual inputs, scores or BioAge without a new consent flow.
Google and Firebase Authentication provide and retain the identity information needed to authenticate you, including your user ID, verified name, email address, optional profile image and provider metadata. We do not place wellness, survey, body-measurement or BioAge data in Firebase, and we do not enable Firebase databases, storage or analytics for the companion.
The required privacy, terms and non-medical acknowledgements are recorded only in this browser and can be withdrawn by deleting the local companion data.
The platform is designed to align with GDPR and PIPA from day one, and is built to be audited by public sector partners.
