The calculator

The cow pregnancy calculator runs entirely in your web browser. The dates, names and tag numbers you enter are not sent to our servers. Your last entry and your herd calving list are stored in your browser’s local storage on your own device so they are there next time. You can delete them at any time with the Clear button or by clearing your browser data.

Feedback

If you send feedback, we receive your message, your rating, the email address you give (optional) and a link containing your calculator settings. We use this only to reply and improve the site. Feedback may be delivered through Web3Forms, a form-delivery service.

Analytics

We may use privacy-friendly, cookie-free analytics (Cloudflare Web Analytics) to count visits. It does not track you across sites.

Advertising

This site may show ads from Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other websites. You can opt out of personalized advertising at Google Ads Settings, and learn more at how Google uses data from sites that use its services. Visitors in the EEA and UK are asked for consent before personalized ads are shown.
