Terms of Use
By using GreenMacros you agree to the following.
Educational use, not advice
All calculators provide estimates for general educational purposes only. They are not medical, nutritional, psychological or training advice, and do not create a professional relationship. Predictive equations carry inherent error; results are starting points to refine against your own real-world data, not prescriptions. Always consult a qualified professional before significant dietary or exercise changes, and particularly during pregnancy or with any medical condition.
No warranty
The site is provided “as is” without warranties of any kind. While we implement formulas carefully from primary sources and cross-check them, we do not guarantee the site is error-free or uninterrupted. To the maximum extent permitted by law, GreenMacros is not liable for any loss or harm arising from use of the site or reliance on its outputs.
Acceptable use
You may use the calculators freely for personal and professional purposes. Do not scrape at a rate that degrades the service, misrepresent the tools as medical devices, or republish content as your own without attribution.
Changes
We may update these terms; continued use after changes constitutes acceptance. Questions are welcome at the address below.
