Privacy Policy

Last updated: February 22, 2026

1. Who We Are

DueDateCalculator.com (“we”, “our”, or “the site”) is a free online pregnancy due date calculator service accessible at www.duedate-calculator.com. For privacy enquiries, contact us at privacy@duedate-calculator.com.

2. Information We Collect

2a. Calculator Inputs

All calculator computations (LMP dates, IVF transfer dates, gestational age, etc.) are performed entirely within your browser using JavaScript. We do not transmit, log, or store any dates or personal health information you enter into our calculators.

2b. Usage Data

Like most websites, we collect standard server log data and use analytics tools (such as Google Analytics) to understand how visitors use the site. This may include your IP address, browser type, pages visited, and time on site. This data is used in aggregate form only and is not linked to personally identifiable information.

2c. Cookies

We use cookies to maintain basic site functionality and to collect anonymous analytics data. We do not use cookies to track you across other websites or build personal profiles. You can disable cookies in your browser settings; this will not affect your ability to use our calculators.

3. How We Use Information

We use the limited information we collect to:

• Understand how our tools are used so we can improve them
• Monitor site performance and diagnose technical issues
• Comply with legal obligations

We do not use your information for advertising profiling, and we do not sell or rent any data to third parties.

4. Third-Party Services

We may use third-party services including Google Analytics and hosting providers. These services have their own privacy policies. Google Analytics collects anonymized usage data; you can opt out using the Google Analytics Opt-out Browser Add-on.

5. Children’s Privacy

Our site is intended for adults and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

6. Your Rights

Depending on your location, you may have rights under GDPR, CCPA, or other privacy regulations, including the right to access, correct, or delete any personal data we hold about you. Since we do not store health data you enter into calculators, there is typically no personal calculator data to delete. For other enquiries, contact us at privacy@duedate-calculator.com.

7. Data Security

We use HTTPS encryption for all connections to the site. As noted above, we do not store calculator inputs on our servers, minimising the risk of health data exposure.

8. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date at the top of this page. Continued use of the site after changes constitutes acceptance of the updated policy.
