Privacy Policy

Last updated: April 18, 2026. FurCalc is built to respect your privacy. This page explains the minimum data we collect and why.

Calculator data

Every calculator runs entirely in your browser. Weights, ages, breeding dates and other inputs are never transmitted to our servers or to any third party. If you clear your browser storage, the data is gone.

Analytics

We use privacy-respecting analytics (Google Analytics or Cloudflare Web Analytics) to understand which pages are useful. Analytics records anonymous page views, approximate country, device type, and referrer. We do not use cross-site tracking cookies.

Advertising

Some pages may include display advertising (e.g. Ezoic or Mediavine). These networks may use cookies to deliver ads. You can opt out of personalised advertising via your browser settings or each network's opt-out page.

Affiliate links

When you click an Amazon or similar affiliate link and make a purchase, the retailer may share a small referral commission with us. We never receive your payment details.

Your rights

Under GDPR (EU/UK) and CCPA (California), you have the right to know what we collect, request deletion, and opt out of sale of personal information. FurCalc does not sell personal information. Contact [email protected] for data requests.
