Your calculator inputs stay on your device

All calculations run in your browser. The numbers you enter are not sent to us or stored on our servers. We save only your preferred units (for example lb or kg) in your browser's local storage, so the next calculator opens with the same units. You can clear this at any time in your browser settings.

Analytics

We use Cloudflare Web Analytics to count visits and see which pages are used. It does not use cookies and does not track you across other websites. It collects basic technical information such as the page visited, referring site, country and browser type.

Hosting

The site is hosted by Cloudflare, which processes standard server data such as IP addresses to deliver pages and protect the site from abuse.

Affiliate links

Some pages contain affiliate links. When you click one and visit a retailer such as Amazon, that retailer may set cookies under its own privacy policy to record that you came from PetCalcKit. See our affiliate disclosure.

Email

If you email us, we use your address and message only to reply to you.
