Cookie Policy
Updated September 2026 · How this site uses cookies
IVF Due Date Calculators uses cookies so the site works, so we can understand traffic, and — if Google AdSense is approved — so advertising can be shown. The due-date calculator itself does not need advertising cookies. Dates you type stay in your browser and are not written to our server as a medical record.
Essential cookies
These are required for security, login (if you are an editor), and remembering the cookie choice you already made. The site’s cookie banner stores a local consent flag named ivfddc_consent so we do not ask on every click. You can still use the calculator if you refuse analytics and advertising cookies.
Analytics cookies
If you allow analytics, we may use Google Analytics to see aggregated page views, device type, and which guides are useful. This is not used to sell IVF cycles or to identify you to a clinic. You can refuse analytics in cookie settings in the footer.
Advertising cookies
If Google AdSense (or similar) is live, advertising partners may set cookies to serve and measure ads. Ads never change Day 3 / Day 5 / retrieval / IUI math. You can refuse advertising cookies here and use Google’s own ad settings as well. See Privacy Policy for the broader data notice.
What we do not cookie
- Embryo transfer dates, beta values, or ultrasound measurements you type into the tool
- A clinic chart or personal health record
- A mailing list unless you submit the newsletter form on purpose
How to change your choice
Use Cookie settings in the footer, or email [email protected] if a control is broken. Browser settings can also block third-party cookies. Blocking essential cookies may stop the consent banner from remembering your choice.
