1. Overview
Calculator200.com is committed to protecting your privacy. This policy explains what information we collect when you visit our site, why we collect it, how it is used, and what your rights are. We have written it in plain English because we believe you deserve to understand it.
The short version: we collect as little as possible, we never sell anything, all calculations stay in your browser, and we use standard analytics tools to understand how to make the site better. If you have questions after reading this, the Contact page is always open.
2. What We Collect
Information You Give Us Directly
The only time we collect personal information is when you voluntarily provide it — specifically, when you submit a message through our Contact form. In that case, we collect:
- Your name — so we can address you properly in our reply
- Your email address — so we can respond to your message
- Your message content — the actual enquiry or feedback you submitted
We do not add you to any mailing list. We do not share your contact details with any third party. Your message is used only to respond to your enquiry.
Information Collected Automatically
Like virtually every website on the internet, our web server automatically records standard access log data when you visit a page. This includes:
- Your IP address (anonymised in analytics)
- The page you visited and the time of the visit
- Browser type and version
- Operating system and device type
- The referring URL (which site sent you here, if any)
This data is used for security monitoring, diagnosing technical problems, and understanding aggregate traffic patterns.
3. Calculator Inputs — Completely Private
This is a deliberate design decision. People use our calculators for sensitive topics — mortgage affordability, salary negotiations, health metrics, debt calculations. We never wanted any of that information touching our servers. So it doesn't.
4. Cookies

5. Google Analytics
We use Google Analytics 4 (GA4) to understand how people use Calculator200.com. We have configured Google Analytics with IP anonymisation enabled. We do not use User ID tracking or cross-site tracking features.
Google's own privacy policy governs how Google handles analytics data: policies.google.com/privacy.

6. Google AdSense
Calculator200.com is funded by advertising served through Google AdSense. Google may use information about your previous visits to this site and other sites to show you advertisements relevant to your interests.
We have no access to or control over the cookies used by Google AdSense. You can manage your Google advertising preferences through Google Ad Settings. You can also opt out of interest-based advertising through aboutads.info or youronlinechoices.eu (EU users).

7. Third-Party Services
Beyond Google Analytics and Google AdSense described above, Calculator200.com does not share your data with any other third parties. We do not use Facebook Pixel, affiliate tracking networks, email marketing platforms, or any data broker service.
The site may contain links to third-party websites for reference purposes. Once you click through to a third-party site, their own privacy policy applies.
8. Children's Privacy
Calculator200.com is a general-purpose tool website not specifically directed at children. We do not knowingly collect personal information from children under the age of 13.
If you are a parent or guardian and believe your child has submitted personal information through our Contact form, please contact us immediately.
9. Data Security
We take reasonable and appropriate technical measures to protect the limited data we do hold:
- HTTPS everywhere — all pages served over HTTPS with a valid SSL certificate
- Access controls — server logs and contact submissions accessible only to authorised personnel
- Minimal data collection — the best way to protect data is not to collect it
- No payment data — we never handle payment card information
