Privacy Policy

1. Data Protection Philosophy

At Decimal Fraction Calculator (accessible via https://decimaltofractioncalculator.online/), protecting user privacy is foundational to our mission. As an educational mathematics utility platform, we believe that calculating numbers, simplifying fractions, or completing homework should never require giving up your personal privacy.

2. Client-Side Browser Execution Guarantee

All calculations, decimal conversions, fraction simplifications, and arithmetic routines run 100% locally inside your web browser's JavaScript engine.

Zero Equation Storage: We do not log, capture, transmit, or store any numbers, fractions, equations, or calculation history you enter into our tools. Once you close or refresh your browser tab, transient calculation inputs are permanently cleared from local browser memory.

3. Data We Collect & Process

Because our web app functions as a static utility without user account registration or mandatory sign-ins:

• No Personal Identifiable Information (PII) Required: You can utilize all tools without registering, supplying an email, or logging in.
• Voluntary Contact Submissions: If you explicitly submit a inquiry via our Contact Form, we process the name, email address, inquiry category, and message text you provide solely to respond to your support request.

4. Local Storage & Cookies

We use browser localStorage exclusively to store your visual display preference (Light Mode vs. Dark Mode). This preference key (theme) allows our site to load in your preferred theme seamlessly across visits.

Third-Party Partners: If third-party web performance analytics (e.g. Google Analytics) or advertising networks (e.g. Google AdSense) are active, they may set standard anonymized analytical cookies subject to their respective privacy terms. For full details on browser storage management, please review our Cookie Policy.

5. GDPR & CCPA User Privacy Rights

Depending on your jurisdiction (such as the European Economic Area under GDPR or California under CCPA/CPRA), you possess specific privacy rights:

• Right to Know & Access: You have the right to request disclosures regarding any personal data collected.
• Right to Deletion: You may request the deletion of any voluntary contact submissions sent to our support team.
• Right to Non-Discrimination: We do not discriminate against users exercising their legal privacy rights. All calculator utilities remain 100% free and fully functional.
• Zero Sale of Personal Information: Decimal Fraction Calculator does not sell, rent, or monetize personal user data to third-party data brokers.

6. Children's Online Privacy Protection (COPPA Compliance)

Our mathematics tools are designed for students, teachers, and general educational purposes. We strictly comply with the Children's Online Privacy Protection Act (COPPA). We do not knowingly collect or solicit personal identifiable information from children under the age of 13.

7. Technical Security & Server Diagnostics

Our website is served over secure, HTTPS encrypted connection channels. Standard server hosting infrastructure (such as CDN edge providers) may record routine diagnostic web server logs (including anonymized IP addresses, user-agent browser strings, and access timestamps) for network security, DDoS defense, and uptime diagnostics.

8. Privacy Policy Contact & Updates

We reserve the right to revise this Privacy Policy periodically to reflect site updates or regulatory changes. Any modifications will be posted directly on this page with an updated timestamp.

For privacy inquiries or data requests, please contact our privacy compliance team via email: [email protected] or submit a message through our Contact Page.
