Terms of Use

Service

Last Sip estimates how much caffeine may remain in your body by a selected bedtime based on drink caffeine content, time, an average caffeine half-life and a simple decay model. The service is provided for general information and personal planning only.

No Medical Advice

Last Sip is not a medical device and does not provide medical advice, diagnosis, treatment, emergency guidance or personalized clinical recommendations. Caffeine sensitivity varies by person and can be affected by age, pregnancy, medication, genetics, health conditions and other factors. Speak with a qualified clinician about sleep problems, caffeine sensitivity, pregnancy, medication interactions or health concerns.

Estimates And Data Sources

Caffeine numbers are approximate. They may come from curated serving averages, product labels or Open Food Facts data returned after a barcode scan. Actual caffeine content can vary by brand, country, serving size, recipe, roast, brewing method and product reformulation. Barcode data can be incomplete or wrong. You are responsible for checking labels and using your own judgment. Last Sip is not a substitute for product labels, professional advice or your own assessment of how caffeine affects you.

Acceptable Use

• Do not misuse, overload, scrape or interfere with the service.
• Do not use Last Sip to provide medical, clinical or emergency services to others.
• Do not attempt to bypass technical protections or use the barcode API route for unrelated automated queries.

Intellectual Property

The Last Sip name, interface, copy, graphics and code are owned by the operator or its licensors unless stated otherwise. Open Food Facts data remains subject to Open Food Facts' own terms and data licenses, including the Open Database License where applicable.

Third-Party Data

Product data returned after barcode scans may come from Open Food Facts. Open Food Facts data can be incomplete, user-submitted, outdated or unavailable. Last Sip may change or remove barcode lookup if the data source, API, rate limits or license requirements change.

Availability

The service is provided on an as-is and as-available basis. We may change, suspend or discontinue features at any time, including barcode lookup if a provider changes its API, rate limits or licensing terms.

Liability

To the fullest extent allowed by law, the operator is not liable for losses caused by inaccurate estimates, incomplete product data, service interruptions or use of the service as a substitute for medical advice. Nothing in these terms limits liability that cannot be limited by law.

Governing Law

German law applies. Mandatory consumer protection rules of the country in which you usually live continue to apply where they cannot be waived by contract.
