Calculators

All calculations happen in your browser with plain JavaScript. The numbers you type are not sent to a server.

What we save on your device

To save you retyping, PawCalc remembers your last inputs for each calculator (weights, ages, mating dates) in your browser’s localStorage, under keys starting with pawcalc:. It never leaves your device and we can’t see it.

The “Ask a follow-up” helper

Some pages have an optional AI helper. Only when you press Ask, your question and a one-line summary of that page’s result are sent to our server and on to an AI model through Vercel AI Gateway to write the answer. We don’t store questions or answers, and there are no accounts. Don’t include names, addresses or other personal details in your question.

Analytics

We use Ahrefs Web Analytics, a cookieless analytics service, to count page views and see which calculators are useful. It does not use cookies or track you across sites.

Hosting

The site is hosted on Vercel, which processes standard server logs (such as IP addresses) to deliver and secure the site.

Medical note

PawCalc offers estimates for information only. It is not veterinary advice. If you are worried about your pet, contact your vet.
