A private dashboard that reads one person's own fitness and recovery data and presents it back to them in plain language.
Training Journal is a personal, single-user application. It is not a product, it is not offered to the public, and there are no other users. It exists so that one person can read their own training history, sleep and recovery trends without exporting spreadsheets by hand.
The account owner, and nobody else. Access requires signing in with the owner's own Google account. There is no sign-up, no sharing feature and no public view.
This is not a medical device. It displays consumer wearable data. It contains no diagnosis, provides no medical advice, and should not be used to make health decisions. Body-composition figures come from consumer bioimpedance hardware and are indicative only.
How health data is accessed, used, stored and shared is described in full in the privacy policy. In short: it is read with the owner's consent, stored privately, never sold, never shared for advertising, and deleted on request.
