Privacy Policy

Calculator Factory ("we," "us," or "our") operates calculator-factory.com. This Privacy Policy explains what information may be collected when you use our website and how it is used. By using the site, you agree to this policy.

Our calculators run in your browser. We do not require an account, and we do not ask you to submit personal information to use calculators. Values you enter into calculators are processed to display results and are not stored on our servers as part of normal calculator use.

We use Google Analytics 4 (GA4) to understand how visitors use Calculator Factory — for example, which pages are viewed and how users navigate the site. This helps us improve content, usability, and decision-support features.

GA4 may collect information such as pages visited, approximate geographic region, device type, browser type, and referral source. Google processes this data according to its own privacy policies. You can learn more at Google's Privacy Policy.

Google Analytics may use cookies or similar technologies to recognize your browser and distinguish unique visits. These technologies help measure site traffic and usage patterns. You can control cookies through your browser settings and may use browser extensions or opt-out tools provided by Google for analytics.

In addition to Google Analytics, our site may rely on hosting and infrastructure providers (such as Vercel) to deliver pages securely and reliably. Those providers may process technical data such as IP addresses and request logs as part of normal web hosting.

Some calculators may reference third-party data sources where noted on the relevant calculator page. Those services are governed by their own terms and privacy policies.

Calculator Factory does not currently display third-party advertising. If we introduce advertising in the future (for example, Google AdSense), we will update this Privacy Policy to describe what data may be collected for ad delivery and measurement, and how you can manage preferences.

We do not sell your personal information. Analytics data is used in aggregate to understand site performance and improve our tools. We aim to collect only what is reasonably necessary to operate and improve Calculator Factory.

Calculator Factory is intended for a general audience. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through our site, please contact us.

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page will reflect the most recent revision. Continued use of the site after changes constitutes acceptance of the updated policy.
