Privacy Policy

Information We Collect

CalcAuthority's calculators run entirely in your browser. The numbers and values you enter into any calculator are not transmitted to our servers, stored, or associated with your identity. We do not collect form submissions through the calculator tools themselves.

We may collect standard, anonymized usage data through analytics services, such as pages visited, referral source, general geographic region (country or state level), device type, and browser type. This data is used to understand how visitors use the site and to improve calculator tools and content. It is not sold or shared with third parties for marketing purposes.

Cookies

Our website may use cookies — small text files stored on your device — for the following purposes:

• Analytics: To track aggregate usage patterns (pages viewed, session duration). This data is anonymized and cannot be used to identify you personally.
• Advertising: Third-party advertising partners, including Google AdSense, may use cookies to serve and measure advertisements on this site. These cookies may be used to show you ads based on your prior visits to this and other websites.

You can control cookies through your browser settings. Most browsers allow you to refuse cookies, delete existing cookies, or set preferences for specific websites. Refusing cookies may affect some site functionality or the relevance of ads shown.

Google AdSense and Third-Party Advertising

CalcAuthority may display advertisements served by Google AdSense and other third-party advertising networks. These networks use cookies and similar tracking technologies to:

• Measure ad performance and impressions.
• Serve ads relevant to your interests based on browsing history across sites.
• Limit how often you see the same ad.

Google's use of advertising cookies enables it to serve ads to you based on your visit to CalcAuthority and other sites. You can opt out of personalized advertising by visiting Google's Ads Settings. You can also opt out of third-party vendor advertising cookies by visiting aboutads.info.

CalcAuthority does not control the data practices of third-party advertising partners. For more information, see Google's Privacy Policy.

Third-Party Analytics

We may use third-party analytics tools such as Google Analytics to understand how visitors interact with the site. These services collect anonymized information about site usage and provide aggregate reports. They do not provide us with personally identifiable information about individual visitors. Google Analytics data practices are governed by Google's Privacy Policy.

Data Retention

We do not store personal information submitted through the calculator tools because none is collected. Analytics data is retained according to the policies of the analytics providers we use (typically 14 to 26 months for Google Analytics). We do not maintain personal profiles of site visitors.

Children's Privacy

CalcAuthority does not knowingly collect information from children under 13. Our calculators are general educational tools with no account registration, data submission forms, or targeted features for minors. If you believe a child has provided personal information through our site, please contact us so we can investigate and remove it.

Your Privacy Choices

You have several options to control how your data is used:

• Browser cookie controls: Use your browser's privacy or settings panel to manage or delete cookies.
• Google ad personalization: Adjust or opt out at adssettings.google.com.
• Network Advertising Initiative opt-out: Visit optout.networkadvertising.org.
• California residents: Under the California Consumer Privacy Act (CCPA), you may have rights to know, delete, or opt out of the sale of personal information. CalcAuthority does not sell personal information. To make a request, contact us at contact@calcauthority.com.
