3. AI Data Processing
The AI Coach feature processes your data as follows:
When you send a message to the AI Coach, relevant context from your current workout is included to provide personalised responses. This context may include: exercise name, equipment type, muscle group, and current session data. This data is sent to Anthropic's API (Claude) for processing and is subject to Anthropic's data usage policies. We do not use your AI conversations to train AI models. Conversation history is stored in our database (Firebase Firestore) and is deleted when you delete your account.
Important: The AI Coach provides general fitness information only. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making significant changes to your exercise routine.
4. Data Storage and Security
Your data is stored on Google Firebase (Firestore) servers. We implement industry-standard security measures including: Firebase Authentication for secure account access; Firestore Security Rules that restrict data access to authenticated account owners; encrypted data transmission (HTTPS/TLS); no plain-text storage of passwords (handled by Firebase Authentication).
While we take reasonable measures to protect your data, no method of electronic storage or transmission is 100% secure. We cannot guarantee absolute security.
