Privacy policy
Last updated 4 October 2026. This policy is short because the site does very little with your data.
The short version
The calculators run entirely in your browser. Your dog's weight, your cat's age, the amount of chocolate — none of it is sent to us, and none of it is stored.
What we collect
Nothing. There are no accounts, no sign-up, no cookies, and no analytics scripts. We do not set a cookie or write to local storage. There is no server-side calculator to send form data to: the arithmetic happens on your device and the page never contacts us.
What our host sees
The site is served by Cloudflare. Like any web host, Cloudflare processes standard request data — IP address, user agent, the page requested — to deliver the page and to protect against abuse. We do not receive or store that data in a form that identifies you.
Links to other sites
Source citations link to veterinary publications. Once you follow one, that site's own privacy policy applies, and we have no control over it.
Children
This site is not directed at children and collects no personal information from anyone, of any age.
If this changes
If analytics or advertising is ever added, this page will be updated in the same change, and the new section will say what is collected and why. A privacy policy that no longer describes the site would be worse than having none.
