Body Battery collects your email address (for authentication and reminders), selfie images taken during scans, questionnaire responses, daily energy scores, and reflection notes you voluntarily enter. We do not collect any data in the background or outside of your active use.
Your selfie is sent to Anthropic's Claude API solely to extract fatigue signals used in scoring. It is not stored by Anthropic beyond the API request. Your images are stored privately in Supabase Storage and are never shared with third parties. Energy scores and reflections are used only to generate your personal forecasts and history.
Your data is retained as long as your account is active. You can request deletion at any time from the Settings page, which permanently removes all your data including images, scores, and reflections.
All data is encrypted in transit (TLS) and at rest. Selfie storage is private — images are only accessible via time-limited signed URLs generated during scoring. Row-level security policies ensure users can only access their own data.
You have the right to access, correct, or delete your personal data at any time. Use the delete account option in Settings, or contact privacy@body-battery.app.
We may update this policy. Significant changes will be communicated via email. Continued use after notice constitutes acceptance.
