Privacy Policy

Site operator

SmallBizMath is operated by SmallBizMath. For any privacy question or request, contact contact@smallbizmath.com.

Calculator data

Every calculator on this site runs entirely in your browser. Numbers you enter — prices, costs, income, rates — are never transmitted to, or stored on, any SmallBizMath server. Closing the tab clears them.

Analytics

Analytics is not currently enabled on this site. If it is enabled in the future, this policy will be updated first, and no raw calculator input values will ever be sent as analytics data.

Advertising

This site displays advertising served by Google AdSense. Google and its advertising partners may use cookies, device identifiers or similar technologies to serve ads based on your prior visits to this or other websites, and to measure ad performance.

You can learn what data Google collects and how it is used at How Google uses information from sites or apps that use our services, and manage or opt out of personalized advertising at Google Ads Settings or optout.aboutads.info.

Consent for visitors in the EU, UK and Switzerland

If you visit from the European Economic Area, the United Kingdom or Switzerland, a consent banner (served through a Google-certified Consent Management Platform integrated with the IAB Europe Transparency & Consent Framework) asks for your permission before any advertising cookie is set or any personal data is used for ad personalization. You can:

• Accept or decline consent for advertising cookies and data use the first time you visit;
• Change your choice at any time by clearing your browser's cookies for this site, which will show the banner again on your next visit;
• Browse and use every calculator on this site whether or not you consent — declining only affects whether ads shown to you are personalized.

No consent is required for the calculators themselves, since they never send your inputs anywhere.

Cookies

SmallBizMath itself does not set any first-party cookies. Cookies you may encounter come from third parties:

• Google AdSense / Google ad partners — used to serve and measure ads, and (where you have consented, if you are in the EU/UK/Switzerland) to personalize them. See Google's cookie policy.
• Google Analytics — only present if analytics is enabled per the "Analytics" section above.

Your choices

You can decline the EU/UK/Switzerland consent banner, use Google's Ads Settings to limit ad personalization, or use a browser/extension that blocks third-party cookies and ad scripts — every calculator will keep working normally either way.

Your rights

If data protection law in your location (such as the GDPR or UK GDPR) applies to you, you have the right to access, correct, delete or restrict use of your personal data, and to lodge a complaint with your local data protection authority. Because SmallBizMath does not itself collect or store personal data from calculator use, most such requests concern data held by Google as an independent controller for its advertising and analytics services — see the links above to exercise those rights directly with Google, or contact us and we will help point you in the right direction.

Changes to this policy

This policy may be updated as the site's analytics, advertising or contact configuration changes. Material changes will update the "last updated" date above.
