1. Local-First Data Storage

Your data is stored primarily on YOUR device:

  • Training logs, programs, and preferences are stored locally using Hive
  • Data remains on your device unless you explicitly use cloud features
  • Clearing browser data or app storage will permanently delete your local data

2. What We Store on Our Servers

Our backend (Firebase) stores minimal data:

  • Authentication credentials (email, Google account ID)
  • AI usage tracking (token counts for rate limiting)
  • Error logs for debugging (anonymized)

3. AI Processing

When you use AI features:

  • Training log text is sent to your configured AI provider for parsing/analysis
  • Chat messages are processed by your AI provider
  • We do not store AI conversation history on our servers
  • Your AI provider may retain data per their privacy policy

Important: Do not enter sensitive personal health information, medical conditions, diagnoses, or other confidential data. This service is intended for training logs only.

4. Third-Party Services

  • Firebase (Google): Authentication, usage tracking
  • AI Providers: Processing via your configured provider
  • Google Sign-In: Optional authentication method

5. Data We Do Not Collect
