Privacy Policy
Last updated: July 13, 2026
Calculator Kong ("we", "us", or "our") operates the website calculatorkong.com (the "Site"). This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using the Site, you agree to the practices described here.
Summary
Calculator Kong is privacy-friendly by design. Every calculator runs entirely in your browser, so the values you enter are processed locally and are never transmitted to or stored on our servers. We do not require accounts, and we do not sell your personal information.
Information we collect
- Calculator inputs: processed on your device only. We never receive, log, or store the numbers you type.
- Local preferences: settings such as your theme, preferred units, and currency are saved in your browser's local storage on your device. They are not sent to us.
- Usage & device data: like most websites, our analytics and hosting providers may automatically collect standard technical information — such as pages viewed, approximate region, browser type, device type, and referring page — in aggregate form.
Cookies and similar technologies
We and our partners may use cookies and similar technologies to operate the Site, remember your preferences, measure traffic, and (where shown) serve advertising. You can control or delete cookies through your browser settings; disabling them may affect some features.
Analytics
We may use privacy-respecting analytics (such as Google Analytics) to understand aggregate usage — for example, which calculators are most popular. This data is used in aggregate and is not used to personally identify you. For information on how Google uses data, see Google's policy.
Advertising
We may display advertising, including ads served by Google and its partners.
- 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 to the Site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalized advertising at aboutads.info.
How we use information
We use the limited information described above to operate and secure the Site, understand and improve performance, and (where applicable) display and measure advertising. We do not use your calculator inputs for any purpose because we never receive them.
Your rights
Depending on where you live, you may have rights under laws such as the GDPR (EU/UK) or CCPA (California) — including the right to access, correct, or delete personal data, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. Because we do not collect account data or receive your inputs, most requests can be honored simply by adjusting your cookie/ad settings as described above. For any request, contact us.
Children's privacy
The Site is intended for a general audience and is not directed to children under 13 (or the minimum age in your jurisdiction). We do not knowingly collect personal information from children.
Third-party links
The Site may link to third-party websites we do not control. Their privacy practices are governed by their own policies, and we are not responsible for their content.
Changes to this policy
We may update this Privacy Policy from time to time. Material changes will be reflected by the "Last updated" date above. Continued use of the Site after changes constitutes acceptance.
