A cycle date or an hCG result is a more sensitive thing to type into a website than most of what people hand over online without a second thought. This page walks through, field by field, what actually happens once you press enter on this site, plus the ordinary traffic logging that comes with any website visit.
Nothing you enter into the due date, pregnancy, ovulation, conception, conception date, hCG doubling, weight gain, trimester, period, implantation or gestational age calculator is sent anywhere. Each one runs as JavaScript in the browser tab open in front of you right now, does its arithmetic locally, and shows you the answer on screen. There is no backend endpoint these calculators call to hand a date off to, so nothing gets logged against your visit, stored in a database, or tied to an account, because none of that infrastructure exists here. Reload the page and every field you filled in is gone.
Like almost any site, this one keeps ordinary server and analytics records: pages requested, a rough location guessed from your IP address, the browser and device you are on, and whatever site sent you here. That tells us which calculators and guides actually get used, and where something is loading slowly. None of it touches the date or number you typed into a form field, since that never leaves your device to begin with.
Two services here set cookies: Google Analytics, for the aggregate usage patterns mentioned above, and Google AdSense, which can use browsing history from elsewhere on the web to pick which ad you see. You can turn ad personalization off in your Google account, reject cookies from the banner on this site, or block them at the browser level entirely; none of that will stop a calculator from working, because the calculators never relied on a cookie in the first place.
The contact form is routed through a third-party processor, Web3Forms. Whatever name, email and message you submit goes to us for the sole purpose of replying; nobody gets added to a list, and nothing gets resold or handed off elsewhere.
A handful of outbound links on this site are affiliate links, and if you click through and buy something, a commission may come back to us at no cost to you. The destination site sets its own cookie once you land there, under its own policy, not this one. Ad delivery itself runs through Google AdSense; Google's own advertising policy page explains how that network uses data across every site that carries its ads.
This is a site for adults thinking through their own pregnancy or fertility planning, not a product aimed at children, and we do not knowingly collect anything from a visitor under 13.
Swap out the analytics tool, ad network or form vendor, and this page gets updated along with the date at the top; we are not going to email you about it, since the contact form is the only place we ever see an email address in the first place.
