Privacy Policy

Effective Date: July 9, 2025

Data Collected via Contact Form

When you use our Contact Us form, we collect the information you provide, including your name, email address, and the content of your message. We do not collect or store any other personal data from your use of the calculators on this Website itself.

How We Use Your Contact Form Data

We use the information you submit through the Contact Us form solely to respond to your inquiry or request. This processing is based on our legitimate interest to communicate with you and provide user support. We do not use this information for marketing purposes or share it with third parties, except as strictly necessary to respond to your request (e.g., if we need to forward your inquiry to a specific technical support partner).

How Your Contact Form Data is Processed and Stored

Contact form submissions are processed by Formspree (a third-party service). Formspree facilitates the secure delivery of your message directly to our email inbox (thecalchub.contact@gmail.com). We do not store your contact form submissions on our website's servers. Your correspondence will be stored in our email inbox for as long as necessary to address your inquiry and for our record-keeping purposes, consistent with our legitimate interests and legal obligations. For more information on how Formspree processes data, please review their official Formspree Privacy Policy.

Third-Party Services

We use Formspree as a third-party service provider to securely process and forward contact form submissions from our Website to our email inbox. Formspree may temporarily store your submission for the purpose of delivery and spam filtering. We encourage you to review Formspree's Privacy Policy for details on their data handling practices.

Website Performance and Analytics (Cloudflare RUM)

To continuously improve the performance, speed, and user experience of TheCalcHub, we utilize Real User Monitoring (RUM) provided by Cloudflare. This technology collects anonymous, aggregated data directly from your browser regarding how our website loads and performs for you.

What Data is Collected

This data includes non-personally identifiable performance metrics such as page load times, rendering performance (e.g., Largest Contentful Paint, Cumulative Layout Shift), network latency, and other technical metrics related to your browser and device environment.

No Personal Data

Cloudflare's RUM is designed to be privacy-first. It does not collect or store any personally identifiable information (PII) about individual users, such as IP addresses (which are discarded at the edge), unique user IDs, or data that could be used to "fingerprint" or track you across websites. It does not use cookies or local storage for this purpose.

Purpose of Collection

This data is used solely for the purpose of analyzing and optimizing our website's performance, identifying areas for improvement, and ensuring a smooth and efficient experience for all visitors.

Third-Party Processor

This performance data is processed by Cloudflare, Inc. You can find more details about Cloudflare's privacy practices, particularly concerning their Web Analytics and RUM, in their official Cloudflare Privacy Policy.

Your Rights Regarding Your Correspondence

Under GDPR, you have certain rights regarding your personal data. If you wish to exercise your right to access, rectify, or have your correspondence deleted from our email records, please contact us directly at thecalchub.contact@gmail.com. We will respond to your request in accordance with applicable data protection laws.

Our Core Principle: We Prioritize Your Privacy

Our calculators operate entirely client-side (in your web browser). This means that the personal data you input into our calculators (e.g., your weight, height, financial figures, specific calculation inputs) is NEVER transmitted to or stored on our servers. Your calculations remain private to you on your device.

1. Information We Do NOT Collect (Related to Your Calculations)

  • Personal Data Inputted into Calculators: We do not collect, store, or have access to any numbers, values, or personal details you enter into our BMI, Mortgage, Scientific, Unit Converter, Calorie Intake, Compound Interest, or ROI calculators. All calculations are performed instantly within your browser.
  • Calculation Results: The results generated by your calculations are also not stored or transmitted to us.

2. Information We May Collect (Non-Personal Usage Data & Third-Party Services)

While we do not collect personal data from your calculator inputs, like most websites, we may gather limited, non-personal information to understand how our site is used and to improve your experience. This may include:

Google Analytics

We use Google Analytics to collect information about your visit, such as:

  • Your IP address (anonymized)
  • Browser type and version
  • Operating system
  • Referring pages and exit pages
  • Date and time of your visit
  • Pages viewed and time spent on pages
  • Which calculators are most popular

This data is used in an aggregated, anonymized form to understand website traffic, identify popular calculators, and improve site performance and design. Google Analytics does not personally identify you.

Cookies

Our website uses cookies for:

  • Essential Functions: To ensure the website works properly
  • Analytics: Google Analytics uses cookies to track website usage and performance
  • User Preferences: To remember your calculator settings during your session

You can control cookie settings through your browser or opt out of Google Analytics by visiting Google Analytics Opt-out Browser Add-on.

3. How We Use the Limited Data Collected

The non-personal usage data and cookie information collected is used solely for the following purposes:

  • To understand how our website is used and to analyze trends
  • To improve the functionality, content, and user experience of our calculators and website
  • To identify which calculators are most popular and useful to our visitors
  • To optimize website performance and loading times

4. Data Sharing

We do not sell, trade, or otherwise transfer your information to outside parties. The only data sharing occurs with Google Analytics, which processes anonymized usage data to provide us with website analytics insights.

5. Data Security

Since we do not collect or store any personal data that you input into our calculators, the risk associated with data breaches regarding your calculation inputs is inherently minimized. We utilize standard security measures for our website hosting to protect against unauthorized access to the limited, non-personal data we do process.

6. Your Data Protection Rights (e.g., GDPR, CCPA)

Depending on your location, you may have certain rights regarding your non-personal data that is collected by third-party services on our site. For example, under the GDPR (General Data Protection Regulation) if you are in the European Economic Area (EEA), you have rights to:

  • Access: Request access to data held about you by third parties.
  • Rectification: Request correction of inaccurate data.
  • Erasure: Request deletion of your data.
  • Object: Object to processing of your data.
  • Portability: Request data portability.

As we do not directly collect or control personal data from your calculator inputs, exercising these rights would typically involve contacting the third-party service providers (e.g., Google Analytics, advertising networks) directly. You can often manage your cookie preferences through your browser settings.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. We encourage you to review this Privacy Policy periodically for any changes.

8. Data Controller Information

The data controller for this website is TheCalcHub. You can contact us at:thecalchub.contact@gmail.com.

9. International Data Transfers

Some of our third-party service providers (such as Google Analytics) may transfer your data outside the European Economic Area (EEA). These transfers are made in accordance with appropriate safeguards, including adequacy decisions or standard contractual clauses approved by the European Commission.

10. Data Retention

We retain your contact form correspondence for as long as necessary to respond to your inquiry and for our legitimate business purposes. Google Analytics retains data for 26 months by default, though this can be configured to shorter periods if needed.
