Your data

Your data, in plain English

A short summary of how Tempest handles your information. The full detail is in our privacy policy.

You choose what to share

Tempest only collects data from the services you connect, and only the kinds you agree to. You can disconnect at any time.

Stored in the UK

Your data is stored in London, encrypted in transit and at rest. Access is limited to the people who need it, and access to records is logged.

AI that's kept on a short lead

Fixed rules do the calculations; the AI writes the words. We send it only what each task needs: no surname, email, date of birth or contact details. Your data isn't used to train AI.

A person checks, on Coached plans

Your coach reviews every message the AI drafts for them before it's sent. Those messages are labelled as drafted with AI.

You can see what's remembered

Everything Tempest remembers about you is on one page in the app. Change it, delete it, download it or switch memory off.

Leave whenever you like

Download your data, or close your account: your login and wellness data are deleted straight away.

Nothing to sell

We don't sell your data, use it for advertising or share it with data brokers. This website uses no cookies, analytics or tracking.
