Privacy-focused by design:
Your drink history and caffeine preferences are stored locally on your device. ClearCaff does not require an account or cloud storage for its core tracking features. Health Connect access is optional, read-only, and used to display sleep comparisons on your device.
Please note: ClearCaff provides estimates based on user-entered information and generalized caffeine half-life calculations. Individual caffeine metabolism varies. ClearCaff is not a medical device and does not provide medical advice, diagnosis, or treatment
