This Privacy Policy describes how CaffeineLog (the "App") handles your information. CaffeineLog is a caffeine-tracking app operated by an independent developer ("we", "us"). We built CaffeineLog to be private by design: your data stays on your device.
CaffeineLog lets you log caffeine intake, create custom drinks, and set preferences such as your daily limit, bedtime, and sensitivity. This information is stored only on your device using Apple's on-device storage. We do not have access to it.
CaffeineLog integrates with Apple Health (HealthKit) only if you explicitly grant permission. When enabled:
All health and fitness data accessed through HealthKit is processed entirely on your device. We do not collect it, transmit it to any server, share it with third parties, or sell it. Health data obtained through the HealthKit API is never used for advertising, marketing, or any use-based data mining, and is never disclosed to third parties for such purposes.
You can grant or revoke CaffeineLog's access to Apple Health at any time in the App's settings, or in iOS Settings → Privacy & Security → Health → CaffeineLog. Revoking access does not delete data previously written to Apple Health; you can manage that within the Apple Health app.
CaffeineLog offers optional in-app purchases and subscriptions ("PRO"). Payments are processed by Apple through the App Store; we never see or store your payment details. To manage entitlements, the App uses RevenueCat, a purchase-infrastructure provider. RevenueCat processes a non-identifying, randomly generated app-user identifier and your subscription status to determine whether PRO features are unlocked. It does not receive your name, email, caffeine data, or health data. See RevenueCat's Privacy Policy and Apple's Privacy Policy.
CaffeineLog may use privacy-preserving, aggregate analytics that do not collect personal information and do not identify you. No health data, caffeine logs, names, emails, or device identifiers that could identify you are collected for analytics.
If you enable reminders, notifications are scheduled locally on your device by the App. No notification content is sent to us.
CaffeineLog is not directed to children under 13, and we do not knowingly collect personal information from children.
Because your data lives on your device, you control it. Deleting the App removes the data CaffeineLog stored on your device. Caffeine entries CaffeineLog wrote to Apple Health can be removed in the Apple Health app.
We may update this Privacy Policy from time to time. Changes will be reflected on this page with a new "Last updated" date.
