Hermes Health is a private, single-user tool run by Thanh An (thanhan.de@gmail.com) on his own computer. It is not offered to the public.
The app reads the owner's own Google Health data (activity, sleep, heart and related metrics) with read-only permission, so that the owner's personal assistant can answer questions about it. Data is processed on the owner's machine and sent only to the AI model provider the owner uses to answer his own questions. It is never sold, shared with third parties or used for advertising. Access can be revoked at any time from Google Account → Security → Third-party connections.
Google Health API data use complies with the Google API Services User Data Policy, including the Limited Use requirements.
