Caffeine Tracker — Last updated: June 12, 2026
1. Overview
Caffeine Tracker ("the App") is a free Android caffeine intake tracker developed by 강건한건강 ("we", "us"). This Privacy Policy explains how we handle information when you use the App.
2. Information We Collect
The App does not collect, store, or transmit any personal information to our servers. It is a 100% offline caffeine tracker with no user accounts and no server-side communication.
Your drink log, caffeine entries, and settings (half-life, daily limit, bedtime, sleep threshold) are stored only on your device using local storage. Uninstalling the App removes all of this data.
3. Health Disclaimer
The App estimates remaining caffeine using a standard half-life elimination model. These figures are estimates only and are not medical advice. Individual caffeine metabolism varies. Consult a healthcare professional about caffeine, sleep, or health concerns.
4. Third-Party Services
The App uses the following third-party service:
- Google AdMob — for displaying advertisements (app open, banner, and interstitial ads). AdMob may collect device identifiers (such as Advertising ID) and usage data to serve personalized or non-personalized ads. For more information, see the Google Privacy Policy.
5. Permissions
The App requests internet access only to load ads. The App does not use or request access to your location, microphone, contacts, camera, or files.
6. Data Storage
All entries and settings are stored locally on the device. There is no cloud sync, no backup, and no account system. Uninstalling the App removes all locally stored data and cached AdMob data.
7. Children's Privacy
The App is not directed at children under the age of 13. We do not knowingly collect personal information from children.
