Privacy policy

Last updated: 27 September 2026

Sageon Performance Coaching (“Sageon”, “we”) provides a coaching platform connecting coaches and their clients. This policy explains what personal data we collect, why, and your rights.

The data controller is Sageon Ltd, a company registered in England and Wales (number 17218060), of 167-169 Great Portland Street, London W1W 5PF, United Kingdom. You can contact us at blake@sageon.co.uk.

What we collect

Account details - name, email address, phone number and password (stored as a secure hash).
Health and fitness data - workouts and lifts you log, bodyweight, body measurements, progress photos, benchmark results, habits, sleep and energy ratings, and check-in responses. This can include date of birth and onboarding notes (such as injuries) shared with your coach.
Nutrition data - meals you log, including photos of food you choose to submit for analysis.
Messages - texts, photos, voice notes and form-check videos exchanged between you and your coach.
Payment data - handled by Stripe. We never see or store your card number; we store your subscription status and Stripe references.
Health app data - if you connect it, we read your daily step count, sleep duration, bodyweight and active calories burned from Health Connect on Android or Apple Health on iOS. Read only, nothing is written back, and only after you allow it on your phone’s own permission screen. You choose which of those to share, and the app works without any of them.
Technical data - push notification subscriptions (if you enable them) and standard server logs.

We do not use advertising trackers or sell your data. We do not collect your location.

How we use it

To deliver the coaching service: your coach sees the data you log so they can programme your training, set your nutrition and review your progress. We also use your data to operate the app (authentication, notifications, billing) and to respond to support requests.

Health app data: what we read is used only inside your own training. Steps, sleep and bodyweight fill in the daily habits and weigh-ins you would otherwise type by hand, and calories burned are shown to you as information about your day. We do not read your heart rate. None of it is used for advertising, sold, or shared with anyone beyond the providers listed below who store it on our behalf, and none of it is transferred to any third party for their own purposes. Disconnect at any time in Account → Health & devices, or revoke the permission in your phone’s settings, and we stop reading immediately. Anything already saved is deleted with your account, or sooner if you delete the individual entries.

AI food analysis: when you submit a food photo or description, it is sent to Anthropic (our AI provider) to estimate its nutritional content, and the result is stored in your log. Photos are used only for this purpose.

Who processes it

Your data is stored and processed by a small set of providers acting under contract: Supabase (database, file storage and authentication), Vercel (hosting), Stripe (payments), Resend (transactional email), Anthropic (AI nutrition analysis) and Sentry (error reporting, hosted in the EU). Sentry receives technical details of errors so we can fix them - it is configured not to send request contents, cookies or headers, so it does not receive the data you log. Some providers process data outside the UK; where they do, transfers are protected by standard contractual clauses or equivalent safeguards.

If you train with a coach on Sageon, that coach sees the data you log through the app. Your coach must not share it further without your consent.

Legal basis

We process your data to perform our contract with you (providing the service you signed up for), and health-related data you choose to log on the basis of your explicit consent, which you can withdraw at any time by deleting the data or your account.

Retention and deletion

We keep your data while your account is active. You can permanently delete your account - and everything in it, including photos, videos, messages and logs - at any time from Account → Delete account in the app. Deletion also cancels any active subscription and is irreversible. Residual copies in encrypted backups expire on the backup cycle.

Your rights

Under UK GDPR you can request access to, correction of, or deletion of your personal data, object to or restrict processing, and request a copy in portable form. Email blake@sageon.co.uk and we will respond within one month. You can also complain to the ICO (ico.org.uk).

Age

The service is not intended for anyone under 16. Clients aged 16-18 should only use the service with a parent or guardian’s agreement, arranged through their coach.

Changes

If we make material changes to this policy we will notify you in the app or by email before they take effect.
