Short version: your due date and pregnancy data never leave your device. The calculator runs entirely in your browser, and we don't collect health information on our servers.
Data on this device
All dates you enter are processed locally in your browser using JavaScript. We do not transmit, store or sell your pregnancy dates, pregnancy week or any health information.
Cookies and analytics
We use a small cookie to remember whether you've accepted the cookie banner, and aggregated analytics (such as page views) to understand how the tool is used. These do not identify you individually and never include medical data.
Third-party advertising
We may display advertising through third-party networks that can use cookies to show more relevant ads. These networks have their own privacy policies and use data in line with their terms.
Your choices
You can clear your browser cookies or use private browsing at any time. Because we store no personal data, you have nothing further to request from us.
