Privacy Policy

Last updated: June 15, 2026

The plain-English version

Your calculator inputs never leave your device. We don't have user accounts, we don't ask for your email, and we don't sell or share personal information with anyone. The site is supported by advertising, and our ad partners use cookies, which you can control. That's the short version. The detailed version follows.

Who operates this site

8calc.com is owned and operated by Stanley King, a licensed real estate broker-salesman in Las Vegas, Nevada (eXp Realty, NV License BS.0143719). Questions about this privacy policy can be directed through the contact page.

What information we collect

Calculator inputs: none. Every calculator on 8calc.com runs entirely in your web browser using client-side JavaScript. The numbers you enter — loan amounts, body measurements, birthdays, income figures, or anything else — are processed locally on your device and are never transmitted to our servers, stored in any database, or shared with any third party. When you close the browser tab, your inputs are gone. We could not retrieve them even if asked, because they were never sent to us.

Personal information: none requested. We do not have user accounts. We do not ask for your name, email address, phone number, or any other personal identifier. There are no sign-up forms, newsletter subscriptions, or registration requirements anywhere on the site. You can use every tool on 8calc.com without providing any personal information whatsoever.

Automatically collected technical data. Like virtually every website on the internet, our hosting provider (Hostinger) maintains standard server access logs. These logs may include your IP address, browser type and version, operating system, referring URL, pages visited, and the date and time of your visit. This data is collected automatically by the web server infrastructure and is used solely for security monitoring, abuse prevention, and aggregate traffic analysis. We do not attempt to identify individual visitors from server logs, and these logs are retained and managed according to our hosting provider's policies.

Cookies and advertising

8calc.com uses Google AdSense to display advertisements. Google and its certified advertising partners use cookies and similar tracking technologies (such as web beacons, pixels, and device identifiers) to serve ads on our site. These technologies may be used to:

• Serve advertisements based on your prior visits to this site or other websites across the internet (personalized advertising)
• Measure the effectiveness of advertisements
• Prevent the same ad from appearing too frequently
• Understand aggregate audience demographics and interests

Google's use of advertising cookies enables it and its partners to serve ads to you based on your browsing history. You can learn more about how Google uses your data at Google's Partner Sites policy page.

Your choices regarding cookies:

• Opt out of personalized ads: Visit Google Ads Settings to control ad personalization for your Google account.
• Opt out of third-party cookies: Visit www.aboutads.info/choices or www.youronlinechoices.eu (for European users) to opt out of interest-based advertising from participating companies.
• Browser settings: Most web browsers allow you to block or delete cookies through their settings menu. Note that blocking all cookies may affect the functionality of some websites.

If you are located in a region that requires prior consent for non-essential cookies (such as the European Economic Area, the United Kingdom, or other jurisdictions with similar regulations), you will be shown a consent notice before personalized advertisements are served. You may decline personalized ads and still use the site with non-personalized advertising.

Google Fonts

This site uses Google Fonts (Space Grotesk and Inter) to deliver consistent typography. When you load a page, your browser requests font files from Google's servers, which means Google receives your IP address and basic browser information for that request. Google's privacy policy governs how they handle that data. No personal information is shared by us in connection with font loading.

External links

Pages on 8calc.com may contain links to external websites, resources, or services. When you click an external link, you leave our site and are subject to the privacy practices of the destination website. We are not responsible for the privacy policies or content of any linked third-party sites. We encourage you to review the privacy policy of every website you visit.

Children's privacy

8calc.com is not directed at children under the age of 13. We do not knowingly collect any personal information from children under 13. Since we do not collect personal information from any user, no age-specific data collection occurs. If you believe a child has provided personal information to us through any channel, please contact us through the contact page and we will take appropriate action.

Data security

Because we do not collect, store, or process personal information through our calculators, the primary data security consideration is the standard server infrastructure provided by our hosting provider, which employs SSL/TLS encryption for all connections (the site is served exclusively over HTTPS), server-level firewalls, and regular security updates. No method of electronic transmission is 100% secure, but we take reasonable steps to protect the limited technical data that passes through our infrastructure.

California residents (CCPA)

Under the California Consumer Privacy Act, California residents have the right to know what personal information is collected, request deletion, and opt out of the sale of personal information. Because 8calc.com does not collect personal information, does not sell personal information, and does not share personal information for cross-context behavioral advertising, there is no personal information to disclose, delete, or opt out of beyond the advertising cookie controls described above.

European users (GDPR)

If you are located in the European Economic Area or the United Kingdom, you have rights under the General Data Protection Regulation including the right to access, rectify, erase, restrict processing of, and port your personal data. Because we do not collect personal data through our calculators or require accounts, the practical exercise of these rights relates primarily to advertising cookies, which you can control through the opt-out mechanisms described above and through the consent notice displayed when you first visit the site.

Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of the site after changes are posted constitutes your acceptance of the revised policy.
