6. Who we share your data with
We share data with the following trusted third-party processors only to the extent necessary to provide our service:
Supabase — database and authentication provider. Your account and session data is stored on Supabase's servers. Supabase is SOC 2 Type II certified. Data is stored in the EU (Ireland).

Anthropic processes this as a data processor under our instructions. Please refer to Anthropic's privacy policy for details of how they handle API data.
RevenueCat — subscription management. RevenueCat receives your subscription status and a pseudonymous user identifier to manage your subscription lifecycle.
Apple — payment processing. All payments are handled by Apple through the App Store. Apple's privacy policy applies to payment data.
Sentry — error monitoring. Anonymised crash reports and error logs are sent to Sentry. No personally identifiable information is included in error reports.

7. AI-generated warmup plans
Prima uses the Anthropic Claude API to generate your warmup plans. When you start a session, a context payload is assembled from your profile, session input, and recent history, and sent to the Claude API. This payload includes:
- Your fitness level, age range, and gender
- Your injury history and any niggles reported today
- Your chosen activity and intensity
- A summary of your recent sessions
- Time of day
This information is necessary to generate a warmup tailored to you. We do not send your name or email to the Claude API. Anthropic processes this data as a processor under our instructions and does not use it to train their models by default. See Anthropic's privacy policy for full details.
8. Data retention
We retain your data for as long as your account is active. If you delete your account:
- Your personal data is deleted or anonymised within 30 days
- Session history is anonymised (not deleted) for aggregate service improvement purposes
- Anonymised data cannot be linked back to you
Subscription records may be retained for up to 7 years for legal and tax compliance purposes, in line with UK financial record-keeping requirements.
