Privacy Policy
Last updated: October 30, 2026.
The short version
The dates you type into our calculators are calculated in your browser and are never sent to us or stored anywhere. There are no accounts, no signups and no forms that collect personal information on this site. The only data involved in running the site is anonymous, aggregate analytics and the ordinary server logs described below.
Calculator data
Every tool on this site runs entirely on your device. Mating dates, heat dates, ovulation dates and results never leave your browser, are not transmitted to our servers, and are not saved after you close the page (beyond your own browser history of the page address, which contains no dates).
Analytics
We use Google Analytics to count visits and see which pages and tools are useful — page views, approximate region, device type and interactions such as using a calculator or downloading the printable chart. This data is aggregate and statistical; we do not use it to identify individual visitors, and advertising features such as cross-site ad personalization are not enabled. Google Analytics sets cookies; you can block or delete cookies in your browser settings at any time, and the site works exactly the same.
If you email us, we receive your email address and whatever you write, and we use it only to reply. We do not sell, rent or share email addresses, and there is no mailing list to join on this site.
Server logs and hosting
Like almost every website, our hosting provider keeps standard request logs (IP address, browser type, pages requested, timestamps) for security and reliability. These logs are not combined with any profile of you — we do not have one.
External links
Pages may link to veterinary references and other resources. Their privacy practices are their own; this policy covers only this site.
Changes and contact
If this policy changes, the new version will be posted here with an updated date. Questions: hello@thedogpregnancycalculator.com.
