Privacy Policy

Last updated: 2026. CatCalculatorOnline.com respects your privacy. Here's the short, honest version.

What you type stays with you

Our tools run entirely in your browser. Your cat's age, weight, and anything else you enter are never uploaded to our servers — they exist only on your device and disappear when you close the page. We never see them.

Analytics & cookies

We use privacy-respecting analytics to understand, in aggregate, which tools and articles help people. You can block cookies in your browser without breaking anything.

Advertising & affiliate links

To keep the tools free, some pages may show ads or link to relevant services (such as cat insurance or pet-supply retailers). If you buy through an affiliate link we may earn a small commission at no extra cost to you — and it never changes what a tool tells you. Partners may use their own cookies.
