Privacy Policy

What We Collect

VisaCalc calculators work entirely in your browser. We do not store any personal data you enter into our calculators — all calculations happen locally on your device and are never transmitted to our servers. If you contact us directly (for example, by email) or submit our calculator correction form, we collect only the information you choose to share — the correction form simply opens your own email app with the details filled in, so we receive only the email you choose to send.

Cookies and Similar Technologies

We use cookies and similar technologies for two things: showing Google AdSense advertisements, and remembering your cookie choice in your browser's local storage. We do not run a separate analytics service. On your first visit a banner lets you accept or decline. If you decline, we ask Google to show only non-personalised ads on later pages; these still use cookies for frequency capping, fraud prevention and aggregate reporting. Visitors in the EEA, the UK and Switzerland are shown Google's certified consent message before personalised ads are served. You can change your choice at any time by clearing this site's data in your browser and visiting again, or block cookies entirely in your browser settings.

Google AdSense & Advertising Partners

We display Google AdSense advertisements. Google, as a third-party vendor, uses cookies (including the DoubleClick DART cookie) and, where enabled, IP-based signals to serve ads based on your prior visits to this site and other sites on the internet. Google may act as an independent data controller for this ad-serving activity. You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising at www.aboutads.info. For details on how Google collects and processes data when you use sites that partner with Google, see How Google uses information from sites and apps that use Google services.

Your Rights (EEA, UK, and Switzerland Visitors)

If you are located in the European Economic Area, the UK, or Switzerland, you have rights under the GDPR and equivalent UK law, including the right to access, correct, or request deletion of any personal data we hold about you, the right to object to or restrict certain processing, and the right to data portability. Since we do not store the information you enter into our calculators and collect minimal data overall, most of these rights will have limited practical application to your use of VisaCalc — but you can exercise any of them, or ask what data (if any) we hold about you, by contacting us using the details below.

California Visitors

Residents of California may have additional rights under the California Consumer Privacy Act (CCPA) regarding the sale or sharing of personal information. We do not sell personal information. If you have questions about your rights under California law, contact us using the details below.

Children's Privacy

VisaCalc is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy from time to time to reflect changes in our practices or legal requirements. The "Last updated" date at the top of this page reflects the most recent revision.
