Terms of Use

These Terms of Use ("Terms") govern your use of the website trackcaffeine.com (the "Site") and the CoffeeLog iOS application (the "App"), both published by VAST FLOW. By using the Site or App, you agree to these Terms. If you do not agree, do not use them.

1. What we provide

The Site is a reference about caffeine content and metabolism, including calculators. The App helps you log and visualize caffeine intake. Both are provided for general informational purposes.

2. Not medical advice

The Site and App do not provide medical advice, diagnosis or treatment. Caffeine values are estimates, and calculations use population-average models that may not reflect your individual physiology. Do not rely on them for medical decisions. Consult a qualified professional for any health concern, including during pregnancy or if you have a medical condition.

3. Acceptable use

You agree not to misuse the Site or App, including attempting to disrupt them, scraping at a scale that burdens our infrastructure, reverse-engineering except as permitted by law, or using them to break any law. The downloadable dataset is provided for personal and research use; attribute TrackCaffeine if you republish it.

4. Intellectual property

The Site, the App, their content, design and the TrackCaffeine and CoffeeLog brands are owned by VAST FLOW or its licensors and are protected by law. Except for the openly published dataset, you may not copy or redistribute our content without permission.

5. Subscriptions

CoffeeLog offers an optional paid subscription through Apple's App Store. Billing, renewal and cancellation are handled by Apple under your Apple ID; manage or cancel anytime in your App Store account settings. Prices and features may change with notice.

6. "As is", no warranties

The Site and App are provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose or non-infringement. We do not warrant that caffeine values or calculations are error-free or that the services will be uninterrupted.

7. Limitation of liability

To the maximum extent permitted by law, VAST FLOW will not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss arising from your use of or reliance on the Site or App. Where liability cannot be excluded, it is limited to the amount you paid us, if any, in the 12 months before the claim.

8. Third-party services and links

The Site and App rely on third parties (such as Apple, RevenueCat, Google/Firebase and Hetzner) and may link to external sites. We are not responsible for third-party content or practices; their terms and privacy policies apply.

9. Changes

We may update these Terms from time to time. Continued use after changes take effect means you accept the revised Terms. We will update the "last updated" date above.

10. Governing law

These Terms are governed by the laws applicable to VAST FLOW, without regard to conflict-of-law rules, except where mandatory consumer-protection laws of your country of residence apply.
