Zero Data Collection Policy

Your Health Data.
Only on Your Device.

h₂éwsōs (CaffeineTracker) was built with a privacy-first architecture. We don't have servers, we don't have analytics, and we don't know who you are.

Local Storage Only

All your logs, bio-metrics, and preferences are stored in the Apple sandbox (UserDefaults) on your physical device. We cannot access it.

No Tracking

The app contains no third-party analytics SDKs (like Google Analytics or Mixpanel). We do not track your usage patterns or tap history.

Anonymous API

Product searches are sent to OpenFoodFacts anonymously. We do not send your personal profile or intake history to external APIs.
