Privacy Policy
How OmniCalc.us collects, uses, and protects information, including how Google AdSense and analytics cookies are used on this site.
Last updated: July 13, 2026
Information We Collect
OmniCalc.us does not require account creation and does not collect personally identifiable information to provide our calculators. All calculations are performed locally in your browser — the numbers you enter are never transmitted to our servers. If you contact us directly (for example, via our Contact page or email), we collect the information you voluntarily provide, such as your name, email address, and message content, solely to respond to your inquiry.
Cookies and Local Storage
We use your browser's local storage to remember your dark mode preference and recent calculation history. This data stays on your device and is never sent to us. Separately, this site displays advertising served by Google, and Google and its advertising partners use cookies (including the DoubleClick/Google Ads cookie) and similar technologies to serve ads based on your prior visits to this and other websites. See the "Advertising" section below for details and your opt-out options.
Google AdSense and Third-Party Advertising
This site is a Google AdSense publisher and displays ads served by Google. Google, as a third-party vendor, uses cookies to serve ads based on your visits to this site and other sites on the Internet. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites. You may opt out of personalized advertising by visiting Google's Ads Settings at https://adssettings.google.com/. You can also opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info/choices/. We do not control the cookies placed by Google or other third-party ad networks and are not responsible for their privacy practices; we encourage you to review Google's Privacy & Terms at https://policies.google.com/technologies/ads for more information about how Google uses information from sites that use its services.
Analytics
We may use third-party analytics services (such as Google Analytics) to understand aggregate site usage — for example, which calculators are most popular and how visitors navigate the site. These services may use cookies or similar technologies and may collect information such as your approximate location, device type, and browsing behavior on this site. This data is used in aggregate and is not used by us to personally identify you.
Your Privacy Rights (GDPR / UK)
If you are located in the European Economic Area or the United Kingdom, you have the right to access, correct, delete, or restrict the processing of your personal data, and the right to object to processing based on legitimate interest, including for personalized advertising. Where required by law, we (and our advertising partners, including Google) will request your consent before setting non-essential cookies. You can manage or withdraw consent at any time via the cookie/consent banner shown on this site, or via Google's Ads Settings referenced above.
Your Privacy Rights (California / CCPA)
If you are a California resident, you have the right to know what personal information is collected about you, to request deletion of that information, and to opt out of the "sale" or "sharing" of personal information for cross-context behavioral advertising, which may include the interest-based advertising described above. You can exercise your opt-out rights via Google's Ads Settings (https://adssettings.google.com/) or by contacting us at the email address below.
Children's Privacy
OmniCalc.us is a general-audience site and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.
