Privacy Policy
Last updated: 2026
This Privacy Policy explains how CentralCalc ("we," "us," or "our") handles information when you visit centralcalc.com (the "Site"). We've tried to write it in plain English. By using the Site, you agree to the practices described here.
The short version
- Our calculators run entirely in your browser. The numbers you type are never sent to us or stored on a server.
- We use standard web analytics and third-party advertising, which rely on cookies and similar technologies.
- We don't sell your personal information.
Information we collect
Calculator inputs. Values you enter into our calculators (such as a car price or interest rate) are processed locally in your browser to show your result. We do not transmit, log, or store these inputs.
Automatically collected data. Like most websites, our hosting provider and analytics tools may automatically receive standard technical information such as your IP address, browser type, device type, referring page, and the pages you view. This is used to understand traffic and keep the Site secure and working.
Cookies and similar technologies
Cookies are small files stored on your device. We and our partners use them to remember preferences, measure traffic, and (once advertising is enabled) serve and measure ads. You can control or delete cookies through your browser settings; blocking some cookies may affect how parts of the Site work.
Advertising
We plan to support the Site with third-party display advertising. When enabled, advertising partners — potentially including Google AdSense — may use cookies and device identifiers to show ads based on your prior visits to this and other websites.
- Third-party vendors, including Google, use cookies to serve ads based on your visits to the Site and/or other sites on the internet.
- 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.
- You can opt out of personalized advertising from many other vendors at aboutads.info/choices or optout.networkadvertising.org.
Analytics
We may use privacy-respecting analytics to understand which calculators are useful and how the Site performs. Analytics data is aggregated and not used to personally identify you.
Your choices & rights
Depending on where you live (for example, under the GDPR in the EU/UK or the CCPA in California), you may have rights to access, correct, or delete personal information, and to opt out of certain data uses. Because our calculators don't collect personal information you provide, most requests relate to cookies and advertising, which you can manage using the opt-out links above and your browser settings. To make a request, contact us using the details below.
Children's privacy
The Site is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.
Third-party links
The Site may link to other websites. We are not responsible for the privacy practices of those sites; please review their policies separately.
Changes to this policy
We may update this policy from time to time. When we do, we'll revise the "Last updated" date above. Material changes will be reflected on this page.
