Terms of Use
Last updated July 29, 2026. Plain-language terms for using Matcha Ratio.
The short version
Matcha Ratio is a free calculator and set of guides for preparing matcha at home. It's provided as-is, with no account required, and you're welcome to use it for personal, non-commercial purposes. By using the site, you agree to these terms.
Guidance, not professional advice
The ratios, temperatures, and techniques on this site are general culinary guidance based on common tea-preparation practice, not medical, dietary, or professional advice. If you have caffeine sensitivity, are pregnant, or have a medical condition affected by caffeine or diet, check with a doctor before changing how much matcha you drink. The calculator's outputs are estimates meant to get you close to a good bowl — your own kettle, matcha, and taste may call for small adjustments.
No warranty
The site is provided "as is," without warranties of any kind, express or implied. I try to keep the calculator and guides accurate, but I don't guarantee the site will be error-free, uninterrupted, or perfectly suited to your specific equipment or matcha. To the extent allowed by law, I'm not liable for any loss or damage arising from your use of the site — including, but let's be honest, mostly a ruined bowl of tea.
Content and links
The text, guides, and design on Matcha Ratio are original work. You're welcome to link to any page on the site; please don't republish the guides or calculator wholesale elsewhere without asking first — reach out and I'm generally happy to say yes. Some pages link to external sites (like Google's ad settings or Ko-fi); I'm not responsible for the content or practices of sites I don't control.
Changes to these terms
These terms may be updated occasionally; the current version always lives at this URL with an updated "last updated" date. Questions go to gomez.paolomiguel@gmail.com or the contact page.
