1. Overview
www.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 and is retained only as long as reasonably needed for that purpose.
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
- The browser type and version you are using
- The 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. We do not use it to identify individual visitors by name or build personal profiles.
3. Calculator Inputs — Completely Private
This is a deliberate design decision, not an accident. 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.
When you close a calculator tab, any values you entered are gone. We keep no record of what you calculated, when you calculated it, or what result you received.
4. Cookies
Cookies are small text files placed on your device by websites. www.calculator200.com uses only the cookies described below. We do not use tracking cookies for marketing purposes and we do not build advertising profiles.
| Cookie / Service | Purpose | Controlled by | Opt-out |
|---|---|---|---|
| Google Analytics _ga, _gid, _gat |
Anonymised usage statistics — page views, popular calculators, device types. Helps us improve the site. | Google LLC | GA Opt-out |
| Google AdSense IDE, test_cookie |
Serves relevant advertisements based on your browsing history. Managed entirely by Google. | Google LLC | Ad Settings |
You can control cookies through your browser settings. Most browsers allow you to block, delete, or limit cookies. Note that blocking all cookies may affect the functionality of some websites. www.calculator200.com's calculators work fully without any cookies at all — cookies are only needed for analytics and advertising.
5. Google Analytics
We use Google Analytics 4 (GA4) to understand how people use www.calculator200.com. This helps us answer questions like: which calculators are most popular, what devices people use, which pages load slowly, and where visitors come from geographically (at a country or city level, not an address level).
We have configured Google Analytics with IP anonymisation enabled. This means Google truncates IP addresses before storing them, so individual visitors cannot be identified by IP. We do not use User ID tracking or cross-site tracking features.
The data we see in Google Analytics is aggregated — we see "450 people visited the BMI calculator on Tuesday," not "John Smith from Birmingham visited at 3:42pm." Google's own privacy policy governs how Google handles analytics data: policies.google.com/privacy.
To opt out of Google Analytics tracking across all websites, you can install the Google Analytics Opt-out Browser Add-on.
6. Google AdSense
www.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 that are relevant to your interests.
We have no access to or control over the cookies used by Google AdSense. We cannot see which specific ads were shown to you or what data Google used to select them. All of that is governed by Google's advertising policies.
You can manage your Google advertising preferences, including opting out of personalised ads, through Google Ad Settings. You can also opt out of interest-based advertising from many participating companies through aboutads.info or youronlinechoices.eu (EU users).
Google's advertising privacy policy is available at: policies.google.com/technologies/ads.
7. Third-Party Services
Beyond Google Analytics and Google AdSense described above, www.calculator200.com does not share your data with any other third parties. We do not use:
- Facebook Pixel or any social media tracking
- Affiliate tracking networks
- Email marketing platforms
- CRM or data enrichment services
- Any "data broker" or audience profiling 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. We have no control over and accept no responsibility for their privacy practices.
8. Children's Privacy
www.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. We will promptly delete any such information upon verification.
Children under 13 should use this site only with parental supervision. The calculators themselves — maths, percentage, age, BMI, and similar tools — are entirely appropriate for school use and educational purposes.
9. Data Security
We take reasonable and appropriate technical measures to protect the limited data we do hold:
- HTTPS everywhere — all pages on www.calculator200.com are served over HTTPS with a valid SSL certificate, encrypting data in transit
- Access controls — server logs and contact form submissions are accessible only to authorised personnel
- Minimal data collection — the best way to protect data is not to collect it. We collect as little as possible for this reason
- No payment data — we never handle payment card information of any kind
10. Your Rights
Depending on where you are located, you may have specific rights regarding your personal data. Here is a plain-English summary:
To exercise any of these rights, please use the Contact page. We take all rights requests seriously and will respond within 30 days. Please note that since we collect very minimal personal data, many of these rights have limited practical application in the context of www.calculator200.com.
11. International Users
European Union and UK (GDPR / UK GDPR)
If you are located in the European Union or United Kingdom, your data is protected under the General Data Protection Regulation (GDPR) or UK GDPR respectively. Our lawful basis for processing the minimal data we collect is:

If you are an EU or UK resident and believe we have processed your personal data unlawfully, you have the right to lodge a complaint with your national data protection authority. In the UK this is the Information Commissioner's Office (ICO).

12. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we do, we update the "Last updated" date at the top of this page.
We will not make changes that fundamentally alter how we treat your data without making that clear on the site. If you use www.calculator200.com regularly, we recommend checking this page occasionally. Continued use of the site after changes are posted means you accept the updated policy.
