Privacy Policy
Privacy Policy
Learn how Due-Date-Calculator.org approaches privacy, calculator information, cookies, advertising technologies, third-party services and the choices available to visitors.
Calculator-Focused Website
Our website provides informational pregnancy and date-related calculators designed to give estimates rather than medical diagnoses.
Cookies & Advertising
Third-party advertising and technology providers, including Google, may use cookies or similar technologies when their services are enabled.
Health Information Disclaimer
Pregnancy calculations are estimates for general information and should not replace advice from a qualified healthcare professional.
Privacy Policy for Due-Date-Calculator.org
At Due-Date-Calculator.org, the privacy of our visitors is important to us. This Privacy Policy explains, in straightforward language, the types of information that may be received, processed or collected when you visit our website, how that information may be used, how advertising and third-party technologies may operate, and what choices may be available to you.
Due-Date-Calculator.org is primarily an informational calculator website. Our goal is to provide simple online tools that can help users understand estimated dates, pregnancy timelines and related calculations. As the website develops, additional useful calculators and educational resources may be added gradually. This Privacy Policy is intended to cover the main website as well as calculators, informational pages and related features that may become available under the Due-Date-Calculator.org domain.
We believe privacy information should be understandable rather than hidden behind unnecessarily complicated language. For that reason, this page describes both the basic privacy principles of the website and the technologies that may be used when third-party services such as advertising providers are enabled.
Our Core Privacy Policy
Read our Privacy Policy
At due-date-calculator.org, the privacy of our visitors is of extreme importance to us. This privacy policy document outlines the types of personal information received and collected by due-date-calculator.org and how it is used.
Log Files
Like many other websites, due-date-calculator.org may make use of log files. Information inside log files may include Internet Protocol (IP) addresses, type of browser, Internet Service Provider (ISP), date and time stamp, referring or exit pages, and interaction information. Such information may be used to analyze trends, administer the website, understand how visitors navigate the site, identify technical problems and improve the overall service.
Log information is generally used for operational, security, statistical and website-improvement purposes. We do not intend to use ordinary server-log information to personally identify individual visitors.
Cookies and Web Beacons
The basic due-date calculator itself may not require a cookie simply to perform a calculation. However, Due-Date-Calculator.org may use, or allow third-party services to use, cookies, web beacons, local storage or similar technologies when features such as advertising, consent management, analytics or other third-party services are enabled.
Google Advertising Cookies
Google, as a third-party vendor, may use cookies to serve ads on due-date-calculator.org when Google advertising services are enabled.
Google's use of advertising cookies enables Google and its advertising partners to serve advertisements to visitors based on visits to this website and/or other websites on the Internet, subject to applicable privacy choices, consent requirements and Google's policies.
Users may learn more about advertising personalization and available controls by visiting Google Ads Settings.
Some advertising partners may use cookies, JavaScript, web beacons, IP addresses or similar technologies in connection with advertisements displayed on the website. Advertising partners may include Google AdSense and, if disclosed here in the future, other advertising providers.
Third-party advertising systems may automatically receive technical information such as an IP address when an advertising request is made. These technologies may be used to deliver advertisements, measure performance, prevent fraud, limit ad frequency and, where permitted, personalize advertising.
Due-Date-Calculator.org does not directly control cookies set by third-party advertising companies. Visitors should consult the privacy documentation of the relevant third-party provider for additional details concerning its information practices and available opt-out or consent choices.
If you wish to disable or limit cookies, you can usually do so through your web browser's privacy settings. Cookie management options vary between browsers and devices, so please refer to the support documentation for the browser you use.
Information That May Be Processed
The information associated with a website visit can vary depending on the features being used. A basic calculator page can operate differently from an advertising service, analytics system, contact form or other optional feature. For transparency, several common categories are described below.
1. Technical and Device Information
Web servers, hosting providers, security services and similar infrastructure may process technical information required to deliver a webpage to your device. This may include an IP address, browser type, operating system, approximate request time, requested URL, referring webpage, device characteristics and server response information.
This information can be useful for maintaining website security, investigating errors, identifying unusual traffic, measuring basic website performance and making pages work properly across different browsers and screen sizes.
2. Calculator Information
A due-date calculator may ask you to enter information such as the first day of a last menstrual period, menstrual cycle length, conception date or another date necessary to perform a calculation. Such information is entered for the purpose of generating the requested estimate.
We aim to design calculators so they request only information reasonably relevant to the calculation. Users should avoid entering names, addresses, medical record numbers or other identifying information into a calculator field unless a future feature clearly explains why such information is required.
3. Information You Voluntarily Provide
If the website later provides a contact form, feedback form, newsletter or other communication feature, information submitted voluntarily through that feature may be processed in order to respond to the request or provide the requested service.
Such information could include an email address, name or message content. If these features are introduced, this Privacy Policy may be expanded to describe the relevant service provider, retention approach and additional choices where appropriate.
Log Files and Website Administration
Like many websites, Due-Date-Calculator.org may use standard server logs and related technical records. Server logging is a routine component of operating websites and can help administrators understand whether pages are loading correctly, identify technical failures and respond to suspicious or abusive traffic.
Log files may contain IP addresses, browser information, referring pages, requested URLs, date and time information, device-related data and similar technical details. The exact records depend on the hosting environment and services being used.
Where these records are available to us, they may be used to maintain website reliability, prevent abuse, investigate errors, improve performance and understand general traffic patterns. We do not intend to combine ordinary log-file information with information such as your name in order to create a personal medical profile.
Google AdSense and Advertising
Due-Date-Calculator.org may display advertising in order to help support the cost of maintaining and developing the website. Google AdSense may be used as an advertising provider.
Third-party vendors, including Google, may use cookies to serve advertisements based on a user's previous visits to this website or other websites. Google's advertising technologies may enable Google and its partners to select, deliver, measure and improve advertisements.
Depending on applicable privacy requirements and the visitor's choices, ads may use contextual information or other permitted signals. Users can learn more about Google advertising controls through Google Ads Settings.
Advertising does not constitute a recommendation by Due-Date-Calculator.org of a particular medical product, service, healthcare provider or advertiser. An advertisement appearing near pregnancy-related informational content should not be interpreted as medical advice or an endorsement.
Due-Date-Calculator.org does not control every advertisement that may be selected by an automated third-party advertising platform. Advertising providers are responsible for their respective systems, policies and technology. If an advertisement appears inappropriate, users may use available advertising feedback tools or contact the relevant advertising provider where appropriate.
Consent and Regional Privacy Requirements
Privacy and cookie requirements vary between countries and regions. Where required, the website may present visitors with a consent message or privacy choices before certain technologies are used.
For example, websites using Google advertising products may be required to use an appropriate consent management system for visitors in certain European regions. A consent interface can allow visitors to make choices about advertising cookies, personalization and other data uses where those choices are required.
Your experience may therefore differ depending on your location, browser settings, the services currently enabled on the site and the consent choices you have made.
You may also be able to withdraw or change consent through a privacy-options link or consent interface when such functionality is available on the website.
Third-Party Services and Privacy Policies
Third-party services operate under their own privacy policies and terms. Due-Date-Calculator.org's Privacy Policy cannot govern how an independent company processes information within its own systems.
Third parties used by the website may include hosting companies, content delivery networks, security providers, advertising providers, analytics systems or other technical vendors necessary to operate and improve the service.
We encourage users who want additional information about a third-party provider to review that provider's current privacy documentation directly.
In particular, visitors can learn more about Google's privacy practices and advertising technologies through Google's official privacy and advertising resources.
Privacy and Pregnancy-Related Information
Pregnancy information can feel personal. For that reason, users should understand the difference between entering a date into a simple informational calculator and sharing medical information directly with a healthcare provider.
Due-Date-Calculator.org is not a hospital, clinic, emergency service, medical-record system or patient portal. Information entered into a calculator should not be considered a substitute for a confidential consultation with a doctor, midwife or other qualified healthcare professional.
Users should not submit medical records, insurance details, identification numbers, confidential documents, passwords or other unnecessary sensitive information through ordinary calculator fields.
If a future feature requires information beyond the minimum needed for a basic calculation, we aim to explain the purpose of that feature and update relevant privacy information as appropriate.
Medical and Pregnancy Information Disclaimer
Pregnancy most commonly is described using an estimated gestational period of approximately 40 weeks from the first day of the last menstrual period. However, an estimated due date is only an estimate. Individual pregnancies vary, and a calculator cannot determine exactly when a baby will be born.
Factors such as menstrual-cycle variation, uncertainty about the date of the last menstrual period, timing of ovulation, ultrasound findings, assisted reproductive technology and an individual's clinical circumstances can affect pregnancy dating.
For this reason, information generated by Due-Date-Calculator.org is provided for general informational and educational purposes only. It is not intended to diagnose pregnancy, determine the health of a pregnancy, recommend treatment, replace prenatal care or override the advice of a doctor, obstetrician, midwife or other qualified healthcare professional.
A healthcare professional may use clinical information and ultrasound findings when establishing or confirming an estimated due date. If the result produced by this website differs from a due date provided by your healthcare team, follow the guidance of your healthcare professional.
Understanding Due Date Estimates
A due date is better understood as a reference point than as a promise of a particular delivery date. A commonly used method estimates a due date from the first day of the last menstrual period, with pregnancy conventionally counted as approximately 280 days, or 40 weeks, from that date.
This approach is useful but relies on assumptions that do not apply equally to everyone. Menstrual cycles can be shorter or longer than 28 days, ovulation can occur at different times, and a person may not remember the exact date of their last menstrual period.
The American College of Obstetricians and Gynecologists notes that first-trimester ultrasound is an important method for establishing or confirming gestational age. This is one reason a website calculator should be presented as a convenient estimate rather than a clinical determination.
NHS pregnancy guidance similarly describes a due date as an estimated date and explains that pregnancy can normally extend across a range rather than ending precisely on one calculated day. Users should therefore view calculator results as part of general pregnancy information rather than as an exact prediction.
Future Calculators and Tools
Due-Date-Calculator.org may gradually expand beyond a single calculator. Our intention is to create a focused collection of practical pregnancy and date-related tools rather than publishing unrelated calculators simply to increase the number of pages on the website.
Potential future tools may include:
The availability of a tool should not be interpreted as a medical recommendation. Every calculator will need its own explanation, limitations and, where appropriate, references so visitors can understand what is being calculated and how the result should be interpreted.
When additional tools are introduced, this Privacy Policy may also be updated if those tools involve new categories of information, third-party technology or functionality.
Data Minimization and Responsible Tool Design
One of our goals is to keep calculator interactions simple. If a calculator only requires a date to generate an estimate, it should not unnecessarily ask for unrelated information such as a full legal name, mailing address or identification document.
This approach can improve both privacy and usability. It reduces unnecessary data entry while making the purpose of each calculator clearer to visitors.
As new features are developed, we aim to consider whether each requested field is genuinely relevant to the function being provided. Features that have different privacy implications may receive additional explanations or policies where appropriate.
Website Security
Reasonable steps may be taken to maintain the security and reliability of Due-Date-Calculator.org. These can include HTTPS, server security controls, software updates, access controls, backups, abuse prevention and monitoring for suspicious technical activity.
No method of transmitting or storing information on the Internet can be guaranteed to be completely secure. For that reason, users should avoid sending highly confidential information through ordinary website features unless a feature specifically requires it and provides appropriate safeguards.
If we become aware of a significant security issue affecting website functionality or relevant visitor information, we may take reasonable steps to investigate, limit the issue and update affected systems.
External Links
Due-Date-Calculator.org may link to third-party websites, including healthcare organizations, medical references, privacy resources, advertising settings or other useful sources.
A link does not mean that the external website is controlled by Due-Date-Calculator.org. Once you leave this website, the privacy policy, terms, security practices and content standards of the destination website apply.
Users should review the relevant policies of third-party websites when providing personal information to those services.
Children's Privacy
Due-Date-Calculator.org is designed as a general informational website and is not intentionally designed to collect personal information from children.
If a parent or guardian believes that a child has submitted personal information through a feature of the website in a manner that should not have occurred, they may contact the site operator using the contact information made available on the website so the situation can be reviewed.
Information Retention
The amount of time information is retained depends on the type of information and the system that processes it. Technical logs may be retained according to hosting, security or operational needs. Third-party providers may have their own retention schedules.
Information voluntarily submitted through future communication features may be retained for as long as reasonably necessary to respond to the request, maintain relevant records, protect the service or satisfy applicable obligations.
We aim not to retain information unnecessarily where there is no reasonable operational, security, legal or service-related reason to continue holding it.
Your Privacy Choices and Rights
Depending on where you live, privacy laws may provide rights or choices concerning certain personal information. These rights can vary significantly by jurisdiction and may be subject to legal exceptions.
Available choices may include managing browser cookies, adjusting advertising personalization settings, using a consent-management interface where provided, or contacting the relevant service provider regarding information it controls.
- Manage or block cookies through your browser.
- Review Google advertising personalization settings.
- Use available consent or privacy controls.
- Avoid submitting unnecessary identifying information.
- Review third-party privacy policies before using their services.
- Contact us regarding website-specific privacy questions.
Analytics and Website Improvement
Due-Date-Calculator.org may use statistical or analytics technologies in the future to understand how visitors use the website. Information from analytics can help identify slow pages, commonly used tools, navigation problems, browser compatibility issues and other areas where the user experience can be improved.
If analytics tools that use cookies, identifiers or other technologies are enabled, appropriate disclosures and consent mechanisms may be provided where required.
Analytics information should be used to understand website performance and broad visitor behavior rather than to create a medical diagnosis or clinical profile about an individual user.
Editorial Independence and Advertising
Advertising revenue can help fund hosting, development, maintenance and the creation of additional free tools. However, advertising should remain separate from the informational purpose of our calculators and educational content.
An advertiser should not determine the result generated by a due date calculator. Likewise, sponsored advertisements should not influence how a pregnancy calculation formula is explained.
Where advertisements are displayed elsewhere on the website, we aim to distinguish advertising areas from calculator controls and editorial information so users can understand which elements are part of the website and which are provided through an advertising platform.
Health Content, Transparency and Trust
Pregnancy is a health-related topic, so extra care is appropriate when publishing information that people may use to understand pregnancy dates or timelines. Our goal is to provide clear explanations, avoid exaggerated accuracy claims and distinguish informational estimates from professional medical advice.
We aim to support trustworthy content by describing calculation methods, explaining limitations, referencing reputable medical sources where appropriate, maintaining visible policies and correcting information when reliable guidance changes.
We do not claim that an online calculator can guarantee a delivery date. We also do not claim that a calculator can replace ultrasound dating, prenatal care or an individualized assessment by a healthcare professional.
As the website expands, informational pages may include additional source references, editorial-review information and update dates to help visitors understand when content was reviewed and where important health information originated.
Changes to This Privacy Policy
Due-Date-Calculator.org may update this Privacy Policy periodically. Changes may be necessary when the website adds a new calculator, advertising service, analytics provider, communication feature, consent system or other technology.
Updates may also be made to improve clarity or reflect changes in applicable requirements or third-party policies. When this page is materially revised, the "Last updated" date near the top of the policy should be changed accordingly.
Visitors are encouraged to revisit this page periodically if they want to stay informed about the website's privacy practices.
