The short version
FurCalcs is a set of free calculators. Everything you type into a calculator — your pet's weight, age, what it ate — is processed entirely in your browser and never sent to our servers. We don't have accounts, we don't ask for your name, and we don't sell data.
What we do collect
Analytics. We use Google Analytics 4 to understand which calculators people use and how they find us. This involves cookies and collects information such as pages visited, approximate location (city level), device and browser type. We use it in aggregate only. You can opt out with theGoogle Analytics opt-out browser add-on.
Server logs. Our hosting provider (Cloudflare) processes standard technical logs — IP address, user agent, requested URL — to serve the site and protect it from abuse.
Advertising
We may display advertising served by Google AdSense. If we do, Google and its partners may use cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this and other websites. You can manage ad personalization atGoogle Ads Settings, and learn how Google uses data from partner sites atpolicies.google.com/technologies/partner-sites.
Cookies
Cookies on this site come from the third-party services above (analytics and, if shown, advertising). The calculators themselves work without any cookies. You can block or delete cookies in your browser settings; every tool on this site keeps working.
Children
FurCalcs is a general-audience site and does not knowingly collect personal information from children under 13.
Your rights
Depending on where you live (GDPR in the EU, CCPA in California, and similar laws), you may have rights to access or delete personal data. Since we hold no accounts or profiles, such requests usually concern the third-party services above — but if you contact us at[email protected], we'll help you figure out where to direct them.
