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 are used for security, troubleshooting, and basic traffic analysis, and are retained for up to 30 days.

Analytics. We use analytics to understand which calculators are popular and how the site is used. Analytics may set cookies on your browser. You can opt out using your browser's privacy settings or the relevant provider opt-out tools.

Advertising

We display advertisements served by third-party 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 aboutads.info.

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.

Children

This site is suitable for general audiences and does not knowingly collect personal information from children. There is no 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 server logs, most such rights produce no meaningful result. For any concerns, contact 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.

Note: This is a general privacy policy template. For full compliance with GDPR, CCPA, or other regional laws you may need additional provisions. We recommend a lawyer review this before a high-traffic launch.
