Hosting

Website and Trévor assistant hosted by Infomaniak Network SA (Geneva, Switzerland), Geneva data centre, ISO 27001 certified. Database never exposed to the Internet: names, messages, answers, notes and watch measurements are encrypted in it, and nightly backups are encrypted and kept for thirty days.

The assistant's answers are produced by a language model operated by Anthropic in the United States, which receives the person's free-text messages, a summary of their follow-up without their first name and any photos or documents they send, after they accept the terms of use or the test agreement. Other providers are involved only if the feature is used: Google Cloud (voice, European endpoints) and Google Wallet (emergency card), OpenStreetMap servers (nearby places), Open-Meteo (weather) and Stripe (online payment).

Trévor processes your health data with your explicit consent, in accordance with the Swiss Federal Act on Data Protection (FADP) and the GDPR, with the right to access, rectify, export and delete from the “My data” menu or by email.

This data is pseudonymised, not anonymous: Trévor records the first name given, the messaging profile name, the messaging ID (the phone number with WhatsApp) and the answers, but no postal address.

Content and liability

Content is intended for information and education, and cites its sources. Care decisions remain with your medical team.

Trévor complements medical follow-up. It stems from a research project whose evaluation study at HUG is awaiting the ethics committee's authorisation, and remains in development. Trévor is not CE nor FDA cleared or approved. The planned initial consumer experience is for general wellness and is not intended to diagnose, screen for, monitor, treat, cure or prevent disease. Future medical functions require applicable regulatory authorization.
