Privacy Policy — Date of Birth Calculator

Last updated: 6 July 2026

Our Privacy Commitment

The Date of Birth Calculator and its related tools (the “Service”) are designed to be private by default. Every calculation — your age, birthday countdown, zodiac details, date differences and more — is performed entirely within your web browser on your own device. The dates you enter are never transmitted to us, uploaded to any server, or stored anywhere by us.

In short: we do not see, collect, sell, or share the birth dates or any personal information you type into the calculator.

Information We Do Not Collect

We do not require you to create an account, sign in, or provide any personal details to use the Service. Specifically, we do not collect:

Your date of birth or any dates you enter, your name, email address, or contact details, or any results generated by the calculators. These values exist only temporarily in your browser’s memory while you use the tool and disappear when you close or refresh the page.

How Your Data Is Processed

All processing happens client-side using JavaScript that runs locally in your browser. When you press a “Calculate” button, your inputs are used on your device to produce a result which is displayed back to you. Because this computation never leaves your device, your information is not exposed to us or to any third party during normal use of the Service.

If you choose to use the “Copy”, “Share”, or “Download PDF” features, those actions are initiated by you and handled by your own device or browser (for example, your clipboard or your operating system’s share menu). We do not receive a copy of anything you share.

Cookies and Local Storage

The Service does not use tracking cookies to identify or profile you. We may use your browser’s built-in preferences (such as your operating system’s light or dark mode setting) to display the site appropriately, but this happens locally and is not linked to your identity.

Third-Party Resources

To display the site’s typography, we load web fonts from Google Fonts. When your browser requests these fonts, Google may receive standard technical information such as your IP address and browser type, as described in Google’s own privacy policy. We do not control and are not responsible for the data practices of third parties. If you prefer, you can block third-party font loading in your browser; the Service will still function using your device’s default fonts.

The Service does not embed advertising networks and does not run behavioural advertising.

Data Security

Because we do not collect or store your personal data, there is no personal database that could be breached on our side. The site is served over an encrypted HTTPS connection to help protect data in transit between your browser and any resources it loads.

Children’s Privacy

The Service is a general-purpose utility and is not directed at children. Because we do not knowingly collect personal information from anyone — including children — no special data-collection concerns arise. Parents and guardians may use the calculators freely, for example to check a child’s school-age eligibility.

Your Rights

Since we do not hold any personal data about you, there is nothing for us to access, correct, export, or delete on your behalf. You remain in full control: clearing your browser or closing the tab removes any values you entered. If you have questions about your privacy rights under laws such as the GDPR or CCPA, you are welcome to contact us using the details below.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes to the Service or to legal requirements. When we do, we will revise the “Last updated” date at the top of this page. We encourage you to review this page periodically.
