Terms of Use

CaffCalc, including its calculator, planner, tracker, articles and downloadable or shared results, is provided for general educational and informational purposes. By using it, you agree to use reasonable judgement and remain responsible for your decisions.

CaffCalc is not medical advice and does not diagnose, prevent, monitor or treat any condition. Estimates are not a determination that a caffeine dose is safe, appropriate or compatible with sleep, pregnancy, medication or a health condition. Consult a qualified healthcare professional for personal guidance. Seek urgent help for severe or concerning symptoms.

Calculations use simplified half-life assumptions. Actual caffeine content, absorption, metabolism, sensitivity and sleep effects vary. We do not warrant that estimates, drink data, articles or availability are complete, current, error-free or suitable for a particular purpose.

You may use the site for lawful personal and educational purposes. Do not attempt to disrupt the service, bypass rate limits, introduce harmful code, misuse the API or present CaffCalc output as a medical diagnosis.

Local history and favourites may be lost when browser data is cleared, a device is replaced or the application changes. CaffCalc is not responsible for maintaining or recovering locally stored data. Offline availability is provided on a best-effort basis.

Some links are paid Amazon Associate links. CaffCalc may receive a commission from qualifying purchases at no extra cost to you. Product availability, ingredients, caffeine content, prices and retailer terms can change; verify current details with the seller before buying. Purchases are made from the retailer and are governed by its terms. Affiliate relationships do not make a product medically appropriate.

To the extent permitted by applicable law, the site owner is not liable for decisions, losses, health outcomes or other consequences arising from reliance on the site. Nothing in these terms excludes liability that cannot legally be excluded.

These terms may be updated from time to time without notice. Continued use of the site implies acceptance of the latest version.
