Privacy Policy

Caffeine Tracker is a local-first Apple Watch app for estimating active caffeine from entries you log.

Data stored on your device

The app stores caffeine entries, drink amounts, sleep cutoff, sleep caffeine target, and app settings on your device. This data is used to show your active caffeine estimate, sleep-time projection, and watch complication values.

Data we do not collect

Caffeine Tracker does not use accounts, ads, third-party tracking, or remote servers in v1. The developer does not receive your caffeine log or settings.

Analytics

The app does not include analytics at launch. This website may use basic Firebase Analytics for aggregate page usage if analytics is enabled for the website, but it does not receive your in-app caffeine log or app settings.

Notifications

If you allow notifications, the app may schedule local notifications on your device. Notification data is handled by Apple system services and is not sent to the developer.

Health and medical disclaimer

Caffeine estimates are for planning only and are not medical advice. Caffeine metabolism varies by person. Consult a qualified health professional before making medical decisions.
