1. Introduction
This Privacy Policy describes how Pregnancy Due Date Calculator ("we," "us," or "our"), accessible at pregnancy-due-date-calculator.hub2.day, collects, uses, and shares information when you use our due date estimation tool. We are committed to protecting your privacy and being transparent about our practices.
2. Information We Process
2.1. Due Date Calculator Inputs
Our core tool allows you to estimate a pregnancy due date based on your last menstrual period or other dates you provide. All calculations are performed entirely within your web browser using local JavaScript. We do not collect, transmit, or store the dates, cycle lengths, or any resulting due date estimates on our servers. The information you enter stays on your device and is not accessible to us.
2.2. Information You Provide Voluntarily
If you contact us directly via email at hello@pregnancy-due-date-calculator.hub2.day, we will receive your email address and any other information you choose to include in your message. We use this information solely to respond to your inquiry and provide support.
2.3. Automatically Collected Information
When you visit the site, our web hosting infrastructure automatically collects standard server logs, which may include your IP address, browser type, operating system, referring pages, and timestamps. This information is used for security, troubleshooting, and aggregated traffic analysis, and is retained for a limited period.
3. Cookies and Local Storage
3.1. Essential Local Storage
The site may use your browser's local storage to remember your preferences (such as dark mode or measurement units) for your convenience. This data is stored locally on your device and is not sent to our servers. You can clear this data through your browser settings at any time.
3.2. Advertising Cookies
We use Google AdSense to display advertisements. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this site or other websites. These cookies allow Google and its partners to show you more relevant ads. A full list of ad technology providers we may work with is available in the Google AdSense consent management platform presented on your first visit.
For visitors in the European Economic Area (EEA), the United Kingdom, or Switzerland, we use a Google-certified Consent Management Platform (CMP) that integrates with the IAB Europe Transparency & Consent Framework. You will be shown a consent banner where you can accept or reject the use of cookies and other identifiers for personalized advertising and related purposes. Your choices apply only to this site and can be updated at any time by clicking the "Privacy & Cookie Settings" link in the footer.
For visitors in California and other US states with applicable privacy laws, you may opt out of the "sale" or "sharing" of your personal information for targeted advertising by clicking the "Your Privacy Choices" link in the footer, which will present a CCPA/CPRA-compliant opt-out mechanism.
