Site operator

SmallBizMath is operated and published by KaiDigital SpA, a Chilean technology company. Editorial direction: Jorge Corsi. 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 and rates—are not transmitted to or stored on a 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

Google requires publishers serving personalized ads in the European Economic Area, the United Kingdom and Switzerland to use a Google-certified Consent Management Platform. When advertising is available to visitors in those regions, Google's privacy message may ask them to accept, reject or manage advertising choices.

• You can accept, reject or manage the choices offered in that message.
• You can continue using every calculator whether or not you agree to personalized advertising.
• You can also limit ad personalization through Google Ads Settings.

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

Cookies

The calculator features do not need cookies. Advertising, consent and optional analytics providers may use cookies or local storage when their services are active:

• 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.

Contact messages

If you email SmallBizMath, the email address and information you choose to include are used to read and respond to your message. Do not include passwords, payment-card details or confidential financial records.

Vetted leads service

The vetted business leads service is not yet active. SmallBizMath does not currently accept lead-pack orders or payment information through this website. This policy will be updated before that service begins collecting order information or delivering paid data.

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 applies to you, you may have rights to access, correct, delete or restrict use of personal data. Calculator inputs are not collected by SmallBizMath. Requests concerning a message you sent directly can be submitted through the contact email; requests concerning Google advertising data can be managed through the Google links above.

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.
