Privacy Policy

Last updated: 11 June 2025

Overview

thecalcu.com is a free, ad-supported calculator platform. We are committed to being straightforward about what data we collect and why. The short version: we do not collect, store, or sell your personal data. Your calculation inputs stay on your device. We use standard analytics and advertising tools that may collect anonymised usage data as described below.

1. Information We Collect

thecalcu.com does not require you to create an account or provide any personal information to use any calculator. We collect:

a) Analytics data (via Cloudflare Analytics & Google Analytics 4)

We use Cloudflare Analytics and Google Analytics 4 to understand how visitors use the Site. This may include:

  • Pages visited and time spent on each page
  • Country and city-level location (derived from IP address, not stored)
  • Browser type, device type, and operating system
  • Referring website or search engine
  • Calculator interactions (which calculators are used most)

Cloudflare Analytics does not use cookies and does not track individuals across sites. Google Analytics 4 may use cookies; see Section 4 for more detail.

b) Advertising data (via Google AdSense)

thecalcu.com displays advertisements served by Google AdSense. Google may use cookies and similar technologies to show you relevant ads based on your browsing history and interests. This is controlled by Google's own privacy policies, not ours.

c) Calculation history (stored locally on your device)

If you use a calculator, your last 10 calculations for that calculator are saved in your browser's localStorage. This data never leaves your device — it is not sent to our servers. You can clear it at any time by clearing your browser's site data or using the “Clear history” button within the calculator.

2. What We Do Not Collect

We do not collect, store, or process:

  • Your name, email address, or contact details
  • Your calculator inputs (they are never sent to our servers)
  • Financial data, income, investment amounts, or tax figures you enter
  • Payment or banking information
  • Device identifiers or persistent user profiles

4. Cookies

thecalcu.com itself does not set first-party cookies beyond what is technically necessary for the site to function. However, third-party services we use may set cookies on your device:

  • Google Analytics 4 — sets measurement cookies to track sessions and events. You can opt out via Google's opt-out browser add-on.
  • Google AdSense — sets advertising cookies to serve personalised ads. You can manage your Google ad preferences at adssettings.google.com.

You can control or disable cookies through your browser settings. Note that disabling cookies may affect the functionality of some third-party features but will not affect your ability to use the calculators.

5. Third-Party Services

We use the following third-party services. Each has its own privacy policy:

  • Cloudflare Pages — hosting and CDN. Privacy policy: cloudflare.com/privacypolicy
  • Google Analytics 4 — usage analytics. Privacy policy: policies.google.com/privacy
  • Google AdSense — advertising. Privacy policy: policies.google.com/privacy

We are not responsible for the privacy practices of these third parties. We encourage you to review their policies.

6. Children's Privacy

thecalcu.com is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through our Site, please contact us and we will take steps to delete it.

7. Data Security

Since we do not collect or store personal data on our servers, the risk of a data breach affecting your personal information is minimal. Your calculation inputs exist only in your browser and are never transmitted to us.

The Site is served over HTTPS and hosted on Cloudflare's global CDN, which provides DDoS protection and secure delivery.

8. Your Rights

Depending on your location, you may have rights under applicable data protection laws (including India's Digital Personal Data Protection Act, 2023, and the EU's GDPR where applicable). Since we do not store personal data, most of these rights are automatically satisfied. If you have a specific request, contact us at the address below.

To opt out of personalised Google advertising, visit adssettings.google.com.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date at the top of this page. We encourage you to review this page periodically. Continued use of the Site after changes are posted constitutes your acceptance of the revised policy.
