What you enter

The calculators run in your browser. The weights, ages, dates and breeds you enter are not sent to us. The “copy link” button puts your entries in the web address so you can share a result: anyone with that link sees them.

Cookies and tracking

Apart from advertising (below), we don't set cookies or use analytics scripts. Our hosting provider, Cloudflare, processes standard server logs such as IP address and page requested, to deliver the site and protect it from abuse.

Advertising

We show ads served by Google. Google and its partners may use cookies to show ads based on your visits to this and other sites. You can manage personalised ads at Google Ad Settings, or opt out at aboutads.info.
