The LastSip calculator, including all content, features, and functionality, is owned by LastSip and protected by copyright, trademark, and other applicable intellectual property laws.
LastSip is provided for informational purposes only. It offers estimated cutoff times, planning tools, and personalized recommendations based on user input. While grounded in research, individual responses to caffeine can vary due to metabolism, health conditions, medications, and other factors.
The calculator does not offer medical advice. Please consult a healthcare professional for guidance on caffeine use and its potential effects on your health and sleep.
You use LastSip at your own risk. We are not liable for any outcomes, side effects, or damages related to your use of the calculator.
All results should be considered general recommendations. Everyone’s sensitivity to caffeine is different, and the model cannot account for every variable.
We may update these terms from time to time. Continued use of LastSip after changes are posted means you accept the revised terms.
These terms are governed by the laws of the United States.
