Third-party services

Fight relies on a small number of trusted services to operate:

• Supabase for the cloud database and authentication. Your data is stored on Supabase servers in the US. Supabase privacy policy
• RevenueCat for subscription management. It receives your purchase and device identifier, not your training data. RevenueCat privacy policy
• An AI provider to generate coach responses. Messages are processed to produce a reply and are not used to train models.
• Apple for App Store payment processing. We never see your card details.

We do not share your data with any other third parties.

Data retention and deletion

Your data is stored for as long as your account is active. You can delete your account and everything attached to it at any time by emailing us at the address below.

When you delete your account, all training logs, profile data, AI coach conversations, and personal information are permanently removed from our servers within 30 days. See the support page for the steps.

Security

All data is transmitted over HTTPS and stored with encryption at rest. Authentication is handled by Supabase Auth using industry-standard practices. You can also enable Face ID or Touch ID for local device security.

Children's privacy

Fight is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it.

Your rights

Wherever you live, you can ask us for a copy of the data we hold about you, ask us to correct it, or ask us to delete it. Email the address below and we will handle it. We will not charge you or make the app worse for exercising these rights.

Changes to this policy

We may update this policy as the app evolves. If we make significant changes, we will notify you through the app. Continuing to use Fight after changes are posted means you accept the updated policy.
