Privacy Policy

1. Overview

At Mixed Numeral Calculator ("we", "our", "us"), we take your privacy seriously. This Privacy Policy explains what information we collect (if any), how we use it, and your rights regarding your data when you use our website at www.mixednumeralcalculator.com.

The short version: your fraction calculations are 100% private. All 7 calculator modes — add, subtract, multiply, divide, simplify, decimal-to-mixed, and mixed-to-decimal — run entirely in your web browser. No input values, no calculation results, and no mathematical data are ever sent to our servers.

2. Information We Collect

Calculator Data — None Collected

We collect zero data from your calculations. All mixed number operations, conversions, and simplifications are performed entirely in your browser using client-side JavaScript. No whole numbers, numerators, denominators, decimal values, or results are ever transmitted to our servers, stored in any database, or shared with any third party. Your math stays on your device.

Information You Voluntarily Provide

If you contact us through our contact form, we may collect:

• Your name, email address, and the content of your message
• The subject category you select (e.g., "Calculator Feedback", "Report a Bug")

This information is used solely to respond to your inquiry and is never shared with third parties for marketing purposes or sold to data brokers.

Automatically Collected Information

When you visit our website, we may automatically collect standard web analytics data:

• Browser type and version (e.g., Chrome 120, Safari 17)
• Operating system (e.g., Windows, macOS, iOS, Android)
• Pages visited on our site and time spent on each page
• Referring website URL (how you found us)
• Approximate geographic location (country/region level only — never street-level)
• Screen resolution and device type (mobile, tablet, desktop)

This information is collected exclusively to improve the Website's performance, design, and user experience. It is never used to identify individual users.

3. Calculator Data Privacy — In Detail

We want to be crystal clear about how your calculator data is handled across all 7 operation modes:

• Addition & Subtraction: The whole numbers, numerators, and denominators you enter for both Fraction A and Fraction B are processed entirely in your browser. No data leaves your device.
• Multiplication & Division: Same as above — all improper fraction conversion, cross-multiplication, and reciprocal operations happen locally.
• Simplify Mode: The single mixed number you enter for simplification is reduced using the GCF algorithm in your browser. Nothing is transmitted.
• Decimal to Mixed Number: The decimal value you type is converted to a fraction in your browser. We never see your input.
• Mixed Number to Decimal: The mixed number is divided locally to produce the decimal result. No server communication occurs.

The visual SVG pie charts, the interactive process flow diagram, and all animation rendering are also performed entirely on your device using client-side code.

4. Cookies

We may use essential cookies to ensure the website functions properly:

• Language preference cookies — to remember your selected language across pages
• Essential functionality cookies — to maintain site navigation and user preferences

We do not use tracking cookies for advertising purposes, behavioral profiling, or cross-site tracking. We do not participate in any advertising networks or programmatic ad exchanges.

5. Third-Party Services

We may use the following third-party services, each with their own privacy policies:

• Google Fonts — to load the Inter and Outfit typefaces for our premium design. Google may collect your IP address when fonts are loaded. Google's Privacy Policy.
• Google Analytics — to understand how visitors use our site (which pages are popular, how long users stay, etc.). Analytics are configured with privacy-first settings: IP anonymization is enabled, cross-site tracking is disabled, and no advertising features are active.

We do not use any third-party services that have access to your calculator inputs or results.

6. Data Sharing

We do not sell, trade, rent, or monetize your personal information in any way. We will not share your information with any third party except:

• When required by law, court order, or legal process
• To protect our rights, property, or the safety of our users
• With your explicit consent

7. Data Retention

Contact form submissions are retained only as long as necessary to respond to your inquiry and maintain a record of communication, typically no longer than 12 months. Web analytics data is retained in aggregated, anonymized form and cannot be used to identify individual users.
