Privacy Policy
Last updated July 29, 2026. Matcha Ratio (matcharatio.com) is a single-page tool and guide site. This page explains what data is and isn't collected when you use it.
What this site collects directly
There are no accounts, logins, or forms on Matcha Ratio. The calculator and whisking timer run entirely in your browser; your bowl size, style, and strength selections are not sent to or stored on any server. If you email the address on the contact page, that message and your email address are only used to reply to you.
Analytics (Vercel Web Analytics)
This site is hosted on Vercel and uses Vercel Web Analytics to see aggregate traffic, such as which pages are visited and roughly how much traffic the site gets. It's designed to work without setting tracking cookies or storing personal identifiers tied to you individually. See Vercel's privacy policy for details on how Vercel itself handles this data.
Other embedded services
The footer includes an optional Ko-fi "buy me a matcha" widget, loaded directly from Ko-fi's own servers. If you interact with it, that interaction is governed by Ko-fi's own privacy policy and terms, not this one.
Your choices
- Block cookies and trackers using your browser's built-in privacy controls or a browser extension. The calculator itself works fully without them.
- Contact gomez.paolomiguel@gmail.com with any privacy question, correction, or data request.
Children's privacy
Matcha Ratio is a general-audience site about tea preparation and isn't directed at children. It doesn't knowingly collect personal information from anyone, including children under 13.
Changes to this policy
If this policy changes, the update will be posted on this page with a new "last updated" date at the top. Continued use of the site after a change means you accept the updated policy.
