Who we are

petcalc is an independent project at petcalc.org. You can reach us at contact@petcalc.org.

What we collect

  • No accounts or forms. You don't sign up, and our calculators don't send what you type to our servers.
  • Optional analytics. With your permission, Google Analytics 4 measures page visits and Microsoft Clarity records masked sessions to help us understand navigation and improve the site. These providers process technical information such as device and browser details, page visits, approximate location and cookie identifiers. We do not enable advertising consent or send calculator inputs or results as analytics events.
  • Server logs. Our hosting provider, Cloudflare, processes technical data such as IP addresses to deliver and protect the site.

Analytics choices and cookies

Analytics is off until you select “Allow analytics.” You can reject it and use every calculator. Choose “Analytics preferences” in the footer to change your choice. We honor Global Privacy Control by keeping analytics off when that signal is enabled.

If you allow analytics, Google Analytics may set _ga cookies and Clarity may set _clck and _clsk cookies. We mask calculator inputs, results and page text in Clarity recordings. Links with query parameters or fragments are excluded from analytics.

Rejecting analytics after allowing it clears the analytics cookies we can control and reloads the page to stop further collection. It preserves your saved calculator data. It does not delete data already collected or all cookies held on provider domains. For details, see Google’s privacy policy and Microsoft’s privacy statement.

Data stored on your device

To remember your preferences, our calculators save a few values in your browser's local storage. This data never leaves your device, and you can delete it by clearing your browser's site data. Keys start with petcalc::

  • petcalc:units: your preferred units (US or metric).
  • petcalc:dog: your dog's age, size and breed, so other calculators can fill them in.
  • petcalc:dogAge:last and petcalc:hub:last: your last inputs on the dog age calculator and the lifespan lookup.
  • petcalc:puppyWeight:last: your last puppy weight inputs.
  • petcalc:breed:last: the age you last entered on a breed lifespan page.
  • petcalc:pregnancy:last: your last pregnancy dates, so you can see today’s day count when you return.
  • petcalc:calorie:last, petcalc:calorie:kcal and petcalc:food:last: your last calorie and food inputs, including your food’s calories, and the calorie result passed to the food calculator.
  • petcalc:analytics-consent:v1: your analytics choice.

Shared links

When you share a result, the link contains the values you entered (for example your dog's age and size) so the recipient sees the same result.

Advertising

We don't show ads at the moment. If we add advertising, we will update this policy first to explain how ad partners use cookies and how you can opt out.

Children

petcalc is not directed to children under 13, and we don't knowingly collect personal information from them.

Email

If you email us, we use your message and address only to reply. Email to our address is forwarded by Cloudflare Email Routing.

Changes

We'll update this page and its date when our practices change.
