Privacy policy
Last updated September 26, 2026
We keep this simple: we collect as little as possible.
Our calculators
Our calculators run in your web browser. The numbers you type, like your age, weight, and height, are not sent to us or stored by us. If you use “Copy link to these results,” your numbers are placed in the link itself, so anyone you share the link with can see them.
Accounts and forms
We don’t offer accounts right now, and our meal plan page doesn’t collect any information yet.
Cookies
We use cookies only for Google Analytics, and only if you choose Accept in our cookie banner. These cookies are named _ga and _ga_… and last up to 2 years. If you choose Reject, Google Analytics runs without cookies and sends only limited, cookie-free signals that help us estimate how many people visit. You can change your choice at any time with Cookie settings at the bottom of every page.
Your light or dark mode choice and your cookie choice are saved in your own browser (not as cookies) and aren’t sent to us.
Analytics
We use Google Analytics 4, a service from Google, to see which pages help people most. It records things like the pages you view, how you arrived (for example from a search, another site, or a link with campaign “utm” tags), your approximate location (country and city), and your device and browser. It doesn’t tell us who you are, and Google says Google Analytics 4 doesn’t log or store IP addresses. Google processes this data under its own policies; see how Google uses information from sites that use its services.
Ads
We don’t show ads right now. If we add them, or anything else that uses cookies, we will update this page first and ask for your consent where the law requires it.
Hosting
Our website host may keep standard server logs, such as IP addresses and the pages requested, to keep the site secure and working.
Links to other sites
We link to restaurant websites and research sources. Their privacy policies apply when you visit them.
