Privacy Policy

Who we are

NumberCals (https://numbercals.com) is a free online calculator service. This policy explains what data we collect, why, and how you can control it.

What data we collect

Calculator inputs. When you use a calculator, the numbers you enter are sent to our server only to compute the result. We do not store these inputs. The calculation happens, the result is returned, and the inputs are discarded.

Standard web server logs. Like most websites, our servers log requests including IP address, browser type, referring page, and time. These logs are used for security, troubleshooting, and basic traffic analysis. They are retained for up to 30 days.

Analytics. We use Google Analytics to understand which calculators are popular and how the site is used. Google Analytics may set cookies on your browser. You can opt out via Google's opt-out browser add-on or by using your browser's "Do Not Track" setting.

Advertising

We display advertisements served by third-party advertising networks, including Google AdSense. These networks may use cookies and similar technologies to serve ads based on your prior visits to this and other websites.

You can learn about Google's ad practices and opt out of personalised advertising via Google Ads Settings or by visiting aboutads.info.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this and other sites on the Internet.

Cookies

Our site itself does not set first-party cookies. Cookies on this site come from third-party services (analytics and advertising) listed above. You can disable cookies in your browser settings, though some features (such as ad personalisation) may not work as expected.

Data we do NOT collect

• We do not require accounts or sign-ups.
• We do not store the numbers you enter into calculators.
• We do not sell data to third parties.
• We do not send marketing emails (because we don't collect your email).

Children

This site is suitable for general audiences and does not knowingly collect personal information from children under 13. The site does not have an account system, and no personal information is solicited or stored.

Your rights

Under privacy laws such as the GDPR (Europe) and the Australian Privacy Act, you have rights regarding personal data. Since we do not collect personal data tied to you individually beyond standard web server logs, most rights (access, correction, deletion) do not produce a meaningful result. For any concerns, contact us at hello@numbercals.com.

Changes to this policy

We may update this policy from time to time. Material changes will be noted at the top of this page with a new "Last updated" date.
