Privacy Policy

This Privacy Policy explains how respiratorcalculator.com (“we”, “us”) handles information when you use this website.

The calculator collects nothing

All calculations run entirely in your browser. The concentrations, exposure limits, and other values you enter are processed on your device and are never transmitted to, or stored by, us. We do not require or offer accounts, and we do not ask for personal information to use the tool.

Analytics

We use Google Analytics to understand aggregate, anonymous usage (such as which pages are visited). Google Analytics sets cookies and may process information including your IP address, device, and browsing activity on this site. See Google’s Privacy Policy for details.

Advertising

We may display ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits. You can opt out of personalized advertising by visiting Google Ads Settings, and you can opt out of some third-party vendors’ use of cookies at aboutads.info.

Cookies

Cookies are small files stored by your browser. This site uses them only for the analytics and advertising described above. You can block or delete cookies in your browser settings; the calculator will still function.

Children’s privacy

This site is intended for occupational and educational use by adults and is not directed to children under 13. We do not knowingly collect personal information from children.
