Privacy Policy
At Accurate Ovulation, your privacy is fundamental to everything we build. This policy explains what information we collect, how it is used, and how we protect your data.
Privacy at a Glance
Accurate Ovulation Calculator is designed with a privacy-first architecture. All calculator inputs — including cycle dates, luteal phase lengths, and conception dates — are processed entirely within your browser. We do not transmit, store, or have access to your health data. No user accounts are required, and no personal health information is collected by our servers.
Information We Collect
Calculator Inputs
When you use any of our calculators — including the Ovulation Calculator, Fertility Calendar, Due Date Calculator, and Pregnancy Test Calculator — you enter personal health data such as your last menstrual period date, cycle length, and luteal phase duration. This data is processed entirely within your web browser using client-side JavaScript. It is never transmitted to our servers, stored in any database, or shared with any third party.
Automatically Collected Information
Like most websites, our web servers may automatically collect certain non-personal technical information when you visit our site. This may include:
- Your IP address (which may be anonymized or aggregated)
- Browser type and version
- Operating system
- Referring website URL
- Pages visited and time spent on each page
This information is used solely for maintaining and improving the website's performance and security. It does not include any health-related data you enter into our calculators.
Information You Voluntarily Provide
If you contact us via email or other communication channels (once available), we may collect the information you choose to include in your message, such as your name and email address. This information is used exclusively to respond to your inquiry.
How Information Is Used
Any non-personal information we collect is used for the following limited purposes:
- Operating and maintaining the website — ensuring pages load correctly and features function as intended.
- Improving user experience — understanding which pages are most visited to prioritize content and feature improvements.
- Protecting website security — monitoring for and preventing unauthorized access, abuse, or technical vulnerabilities.
- Responding to inquiries — if you contact us, we use the information you provide solely to address your message.
We do not sell, rent, trade, or otherwise share your personal information with third parties for marketing or advertising purposes.
Cookies
Cookies are small text files stored on your device by your web browser when you visit a website. Our website may use the following types of cookies:
Essential Cookies
These cookies are necessary for the website to function properly. They enable basic features such as page navigation, secure area access, and remembering your preferences within a session. These cookies do not collect personal health information.
Analytics Cookies
In the future, we may use analytics services to understand how visitors interact with our website — such as which pages are visited most frequently and how users navigate between pages. If and when analytics cookies are implemented, they will collect only aggregated, anonymized data. We will update this policy accordingly and provide clear information about any analytics tools used.
Managing Cookies
You can control and manage cookies through your browser settings. Most browsers allow you to refuse cookies, delete existing cookies, or be notified when a cookie is set. Please note that disabling essential cookies may affect the functionality of certain website features.
Data Security
We take the security of your information seriously and implement appropriate technical and organizational measures to protect it. Key security practices include:
- Client-side processing — All calculator computations occur locally in your browser, eliminating the risk of server-side health data breaches.
- HTTPS encryption — Our website uses SSL/TLS encryption to secure data transmitted between your browser and our servers.
- No health data storage — We do not maintain databases containing user health information, calculator inputs, or fertility-related data.
- Regular maintenance — We keep our website infrastructure and dependencies updated to address known security vulnerabilities.
While no method of electronic transmission or storage is 100% secure, our privacy-first architecture minimizes risk by ensuring that your most sensitive data — your health information — never leaves your device.
Third-Party Services
Our website may utilize third-party services for hosting, content delivery, or analytics purposes. These services operate under their own privacy policies and may collect limited technical information (such as IP addresses) as part of their normal operations.
We select third-party providers that maintain appropriate privacy and security standards. However, we are not responsible for the privacy practices of external services. We encourage you to review their respective privacy policies.
Our website may contain links to external websites for educational or informational purposes. These external sites are governed by their own privacy policies, and we do not control or accept responsibility for their content or data practices.
Children's Privacy
Accurate Ovulation Calculator is intended for use by adults and is designed for informational and educational purposes related to reproductive health. We do not knowingly collect personal information from children under the age of 13 (or the applicable age in your jurisdiction). If we become aware that we have inadvertently collected personal information from a child, we will take prompt steps to delete such information. If you believe a child has provided us with personal information, please contact us so that we can take appropriate action.
Policy Updates
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or for other operational purposes. When we make material changes, we will update the "Last Updated" date at the top of this page. We encourage you to review this policy periodically to stay informed about how we protect your information. Your continued use of the website after any changes constitutes your acceptance of the updated policy.
Not Medical Advice
Accurate Ovulation Calculator provides educational and informational tools only. Our calculators generate estimates based on statistical averages and standardized reproductive metrics. They are not intended as medical advice, clinical diagnosis, or a substitute for consultation with a qualified healthcare provider. Always consult a licensed medical professional regarding your reproductive health, fertility concerns, or pregnancy planning.
