Privacy Policy

Last Updated: March 2026

1. Introduction

Welcome to RJ Calculator. We respect your privacy and are committed to protecting any personal data you may share with us. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website.

The Short Version: Our calculators run entirely on your device (client-side JavaScript). We do not save, store, or transmit the numbers, dates of birth, or results you enter into our tools. Your math stays with you.

2. Information We Do Not Collect

Because our tools are designed for simple, instantaneous calculations directly in your browser, we do not collect or store the data you input. This includes:

  • Dates of birth entered into the Age or Birthday calculators.
  • Body weight or lifting totals entered into the DOTS calculator.
  • Numbers entered into our math and utility calculators.

3. Information We May Collect

While we do not store your calculation data, we may collect certain standard web data to ensure our site functions properly:

  • Voluntary Contact Information: If you reach out to us via our Contact Form or email (rjrapture@gmail.com), we will collect your name, email address, and the contents of your message solely to respond to your inquiry.
  • Log Data: Like most websites, our servers automatically record basic, non-personally identifiable information such as your IP address, browser type, referring pages, and timestamp to monitor site health and performance.

4. Cookies and Analytics

We may use cookies (small text files stored on your device) and third-party analytics tools (such as Google Analytics) to understand how visitors interact with our website. This helps us see which calculators are the most popular and how we can improve our user interface (UI).

If we display advertisements on our site, our third-party advertising partners (like Google AdSense) may also use cookies to serve ads based on your prior visits to our website or other websites on the internet.

You can choose to disable cookies at any time through your individual browser settings.

5. Third-Party Links

Our website may contain links to external sites that are not operated by us. Please be aware that we have no control over the content and practices of these external sites and cannot accept responsibility or liability for their respective privacy policies.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time as we add new tools and features to RJ Calculator. We encourage you to review this page periodically for any changes. Any updates will be posted directly to this page.
