Privacy

Last updated September 2026

The short version

Everything you type into a calculator on this site stays on your device. There is no account, no login, and no database of your dog. The pages are static files served from a CDN.

Calculator inputs

Weights, ages, amounts and every other value you enter are processed by JavaScript running in your own browser. They are never sent to a server, because the calculators do not talk to one. Closing the tab discards them.

Cookies

This site sets no cookies of its own and does not use browser storage to track you across visits.

Server logs

The site is hosted on Cloudflare. Like any web host, Cloudflare records standard request information such as IP address, user agent, requested URL and timestamp, and uses it to serve pages, mitigate abuse and protect against attacks. We do not combine that data with anything else, and we do not use it to identify individuals.

Analytics

If privacy-respecting, cookie-free aggregate analytics are added in future, this page will be updated to say so before they go live.

Third parties

The site loads no third-party fonts, scripts or trackers. If affiliate links are added to any page, they will be disclosed in line with our affiliate disclosure, and clicking one will take you to that retailer, whose own privacy policy then applies.

Children

This site is intended for adults responsible for a dog and does not knowingly collect information from children.
