FAQ
Questions and answers
Which watches will work?
We're starting with Garmin, with Apple Watch and others to follow. In testing, Tempest also reads Apple Health exports. We'll say clearly which watches work before the founding group opens.
Do I need a paid plan?
We're planning a Base plan with the AI coach, and a Coached plan that adds a human coach and group calls. Prices aren't set yet, and nothing is for sale. Founding members get a founding price, confirmed before they join.
Is this medical advice?
No. Tempest is a wellness and coaching service. It describes your own data and helps you build habits; it doesn't diagnose or treat anything. If you're worried about your health, speak to your GP or call NHS 111. In an emergency, call 999.
What does the AI do, and who checks it?
Fixed rules work out your baseline, trends and patterns. The AI (Claude, made by Anthropic) turns those results into plain English: your weekly summary, check-ins and replies. Its words are checked automatically before you see them, and if you mention a warning sign such as chest pain, coaching stops and you're pointed to the right help.
On Coached plans, a human coach reviews every message the AI drafts for them before it's sent, and those messages are labelled as drafted with AI.
Is my data used to train AI?
No. Under Anthropic's commercial terms, your data isn't used to train their models, and we don't use it to train any either.
Can I delete my data?
Yes. In the app you can download your data, delete what Tempest remembers about you, or close your account, which deletes your login and wellness data straight away. See your data.
Where is my data stored?
In London, on Google Cloud and Supabase. The AI service is in the United States, and gets only what it needs for each task, under UK transfer safeguards. The details are in our privacy policy.
Who are the coaches?
Coaches are people who help with fitness and everyday habits, working with Tempest. They aren't doctors and don't give medical advice. We'll introduce the founding group's coach before it opens.
What about blood tests?
Blood tests and clinician support are planned for the future. They aren't part of Tempest yet.
Who is behind Tempest?
Tempest is built by Deep Blue AI Ltd, a UK company. Read why we're building it, or email info@tempest.energy.
