Welcome to Combined Gas Law Calculator (combinedgaslawcalculator.org). This Privacy Policy explains what information we collect when you use our gas law calculators and educational content, and how that information is used.
1. Calculator Data
Every calculator on this site, including the combined gas law solver, Boyle's Law, Charles' Law, Gay-Lussac's Law, Avogadro's Law, the ideal gas law, and every unit converter, runs entirely in your browser using JavaScript. The pressure, volume, temperature, and mole values you enter are never transmitted to our servers, logged, or stored anywhere. Closing or refreshing the page clears everything.
2. Contact Information
If you reach out through our Contact page, we collect only the name, email address, and message you choose to provide. This information is used solely to respond to your inquiry and is never sold or shared with third parties for marketing purposes.
3. Automatically Collected Information
Like most websites, we may collect standard technical information automatically, such as approximate location, browser type, device type, referring page, and pages visited, through privacy-conscious analytics tools. This aggregate data helps us understand which calculators are most useful and where the site can be improved; it is not tied to your calculator inputs.
4. Cookies
We use only the cookies required for basic site functionality (such as remembering your selected language) and, where enabled, anonymized analytics cookies. You can disable cookies in your browser settings without affecting any calculator's core functionality.
5. Third-Party Services
Contact form submissions on this site are processed by a third-party form service (Web3Forms) solely to deliver your message to us by email. We do not use that service to track your browsing activity elsewhere on the site.
6. Data Retention
Contact form messages are retained only as long as needed to respond to your inquiry. Calculator inputs are never stored in the first place, so there is nothing to retain or delete on that front.
7. Children's Privacy
This site is an educational tool suitable for students of all ages studying gas laws in chemistry or physics. We do not knowingly collect personal information from children under 13. If you believe a child has submitted personal information through our contact form, please contact us so we can remove it.
8. Your Rights
You may request access to, correction of, or deletion of any personal information you have submitted to us (such as a past contact form message) by reaching out through our Contact page.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised "Last Updated" date.
