MixDesignCalc.com ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our concrete mix design calculators, steel section weight tools, and engineering resources.
We may collect personal information that you voluntarily provide to us when you:
This information may include your name, email address, company/organization name, country of residence, and the content of your message or inquiry. We collect only the minimum information necessary to respond to your request or provide the service you've requested.
This is the most important section for engineers and professionals using our tools. All calculator inputs are processed entirely in your web browser using JavaScript.

What we do NOT do with your information:
MixDesignCalc.com uses cookies and similar technologies to enhance your browsing experience and gather analytics data. A cookie is a small text file stored on your device by your web browser.
Essential Cookies (Required): These cookies are necessary for basic website functionality. They enable core features like page navigation, access to secure areas, and calculator operation. The website cannot function properly without these cookies, and they cannot be disabled.
Analytics Cookies (Optional): We use Google Analytics to collect anonymized data about website usage, traffic sources, and user behavior. These cookies help us understand:
Google Analytics is configured with IP anonymization enabled, meaning your full IP address is never stored. We do not enable Google's advertising features or share data with Google for advertising purposes.
Performance Cookies (Optional): These cookies collect information about website performance — page load times, server response times, and error reports. This helps us identify and fix technical issues quickly.
You can control cookies through your browser settings. Most browsers allow you to:
Note that blocking or deleting cookies may affect website functionality — certain features may not work correctly. However, all calculator tools will continue to function normally since they operate entirely client-side and do not require cookies.
To opt out of Google Analytics tracking across all websites, install the Google Analytics Opt-out Browser Add-on.
MixDesignCalc.com uses the following third-party services, each of which has its own privacy policy:

We may use Google Fonts for web typography. When you load a page using Google Fonts, your browser sends a request to Google's servers. Google may log this request along with your IP address. Google Fonts privacy policy: Google Fonts FAQ
We may use CDN services (such as Cloudflare or similar) to deliver website content faster and improve security. CDN providers may log your IP address and other technical information when serving content. Their privacy policies govern this data collection.
We do not use Google AdSense, Facebook Pixel, or other advertising tracking technologies on MixDesignCalc.com. There are no third-party advertising cookies on our website.
We implement reasonable technical and organizational measures to protect your personal information from unauthorized access, disclosure, alteration, or destruction:
However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your personal information using industry-standard practices, we cannot guarantee absolute security. You are responsible for maintaining the confidentiality of any account credentials you create.
Depending on your location, you may have certain rights regarding your personal information:
You have the right to request information about what personal data we hold about you and to request correction of any inaccurate data. Since we collect minimal personal information (primarily from contact forms), there is typically very little data to access. Contact us via our Contact page to make such a request.
You have the right to request deletion of your personal information. We will comply with such requests within 30 days, except where we are required to retain data for legal or regulatory purposes.
If you subscribed to our newsletter, you can opt out at any time by clicking the "unsubscribe" link at the bottom of any email we send you. You can also contact us directly to request removal from our mailing list.
You have the right to receive a copy of your personal data in a structured, commonly used format. Contact us to request a copy of any personal information we hold.
Some browsers have a "Do Not Track" (DNT) feature that signals to websites that you do not want to be tracked. Our website does not currently respond to DNT signals, as there is no universal standard for interpreting or implementing DNT. However, we minimize tracking as described in this Privacy Policy.
