Privacy Policy

Summary (Plain English)

We understand that IVF is a deeply personal journey, and your privacy matters. Here's the short version of our privacy practices:

• We don't collect your personal data. All calculations happen entirely in your web browser.
• Nothing is stored on our servers. Your transfer dates, due dates, and calculation results never leave your device.
• No account required. You can use all calculator features without signing up or providing any personal information.
• No tracking of your health information. We have no way to see what dates you enter or what results you receive.

The rest of this policy provides more detail about our practices.

Information We Don't Collect

Unlike many websites, we deliberately avoid collecting personal information. Specifically, we do not collect or store:

• Personal health information: Your embryo transfer dates, due dates, gestational age, or any other pregnancy-related data you enter into the calculator
• Account information: We don't have user accounts, so there's no username, password, or profile data
• Financial information: The calculator is free, so we never ask for payment details
• Calculation history: We don't save your past calculations or results
• Personal identifiers: We don't collect your name, address, phone number, or other identifying information through the calculator

All calculations are performed using JavaScript that runs entirely in your web browser. The data you enter stays on your device and is cleared when you close or refresh the page.

Data Comparison: Us vs. Typical Health Apps

To put our privacy practices in perspective, here is how our data collection compares to what typical health and fertility apps collect:

Privacy Features

Our commitment to privacy is built into every aspect of the site. Here are the key features that protect your data:

Information That May Be Collected

While we don't collect personal data through the calculator, some information may be collected through standard web technologies:

Analytics

We may use basic analytics to understand how the site is used. This includes anonymous, aggregated data such as:

• Number of page views
• General geographic region (country level)
• Device type (mobile, desktop, tablet)
• Browser type
• Referring website (how you found us)

This data is anonymized and cannot be used to identify individual visitors. It helps us understand which features are most used and how to improve the site.

Cookies

This website uses minimal cookies. We do not use cookies to track you across the web or to collect personal information. Any cookies that may be set are:

• Essential cookies: Required for basic site functionality
• Analytics cookies: If analytics are enabled, these help us understand site usage in aggregate

We do not use advertising cookies, tracking cookies, or third-party cookies for behavioral targeting.

Form Submissions

If you choose to contact us through the contact form, we will receive the information you voluntarily provide, including your name, email address, and message content.

Contact Form Data

When you submit a message through our contact form, your submission is processed by Formspree, a third-party form handling service. The information you provide is:

• Used solely to respond to your inquiry
• Not shared with other third parties
• Not used for marketing purposes
• Not sold or transferred to others

Formspree stores your submission temporarily to facilitate our response. You can review Formspree's privacy practices on their website.

Third-Party Services

This website uses the following third-party services:

• Vercel: Our hosting provider. Vercel may collect standard server logs including IP addresses for security and performance purposes. See Vercel's privacy policy for details.
• Formspree: Handles contact form submissions. Only processes data you voluntarily submit through the contact form.

We do not use advertising networks, and we do not sell or share data with data brokers or marketing companies.

Your Rights

Because we don't collect personal data through the calculator, there's typically nothing to request access to or delete. However:

• If you've contacted us through the contact form and wish to have your submission deleted, you can email us at info@ivfdatecalculator.org and we will delete your correspondence.
• You can clear any locally stored data by clearing your browser's cache and cookies.
• You can disable JavaScript in your browser, though this will prevent the calculator from functioning.

Children's Privacy

This website is not directed at children under the age of 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can delete it.

Changes to This Policy

We may update this privacy policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. When we make changes, we will update the "Last Updated" date at the top of this page.

We encourage you to review this policy periodically. Your continued use of the website after any changes indicates your acceptance of the updated policy.
