Privacy Policy

Your privacy matters to us. Learn how we protect your personal information.

Last updated: April 25, 2026

Information We Collect

At Pregnancy Due Calculator by Conception, we are committed to protecting your privacy. We do not collect, store, or transmit any personal health information that you enter into our calculators. All calculations are performed entirely within your web browser using client-side JavaScript. This means that the dates you input, such as your last menstrual period date, conception date, or IVF transfer date, never leave your device and are never sent to our servers or any third-party servers.

We may collect limited anonymous usage data through standard web analytics tools. This data includes general information such as page views, browser type, device type, and general geographic region. This anonymous data cannot be used to identify you personally and is used solely to improve our website performance and user experience. We do not use this data for advertising or marketing purposes, and we do not sell or share this data with any third parties for any reason.

How We Use Information

The anonymous analytics data we collect is used exclusively to understand how visitors interact with our website so we can improve the user experience. For example, we may use this data to determine which calculators are most frequently used, which pages have the highest engagement, and how users navigate through our site. This helps us make informed decisions about content improvements, feature development, and overall site optimization.

We do not use any information for targeted advertising, we do not create user profiles, and we do not track individual users across sessions or across other websites. Our use of analytics data is minimal and purpose-driven, focused solely on making our calculators and content as helpful and accessible as possible for expectant parents seeking reliable pregnancy information.

Data Storage and Security

Since all calculations are performed locally in your browser, no personal health data is ever stored on our servers. We do not maintain databases of user inputs, calculation results, or any other personally identifiable health information. This architecture was deliberately chosen to ensure the highest level of privacy protection for our users, particularly given the sensitive nature of pregnancy-related health information.

Our website is hosted on secure servers with industry-standard encryption and security measures. We regularly review our security practices and update them as needed to protect against unauthorized access, alteration, or destruction. While no method of transmission over the internet is 100 percent secure, our design philosophy of keeping all personal data on the user's device eliminates most common data security risks associated with web applications.

Cookies

Our website may use essential cookies that are necessary for the basic functioning of the website, such as maintaining your session and preferences. These cookies do not contain personal health information and are not used for tracking or advertising purposes. We do not use tracking cookies from social media platforms or advertising networks.

If we implement any non-essential cookies in the future, such as analytics cookies that are not already covered by our anonymous analytics setup, we will update this privacy policy and provide clear notice and consent mechanisms before enabling them. You can control cookie settings through your browser preferences at any time.

Third-Party Services

We may use third-party services for website analytics, content delivery, and hosting. These services have their own privacy policies and may collect anonymous data as described above. We carefully select third-party services that uphold high privacy standards and do not sell or misuse user data. We do not share any personal health information with third-party services because we do not collect any such information in the first place.

Children's Privacy

Our website is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you are under 13, please do not provide any personal information to us. If we become aware that we have inadvertently collected personal information from a child under 13, we will take steps to delete that information as quickly as possible.

Your Rights

Since we do not collect or store personal health information, there is no personal data for you to request access to, modify, or delete from our systems. However, you retain full control over any information you enter into our calculators, as this data exists only on your device and is never transmitted to us. You can clear this data at any time by refreshing the page or closing your browser.

If you have any questions or concerns about this privacy policy or our data practices, please do not hesitate to contact us. We are committed to transparency and will respond to any privacy-related inquiries promptly and thoroughly.

Contact Information

If you have any questions about this Privacy Policy, please reach out to us through our contact page. We review all messages and will respond as soon as possible. This privacy policy may be updated periodically to reflect changes in our practices or for legal, operational, or regulatory reasons. Any changes will be posted on this page with an updated revision date.
