Privacy Policy

1. Client-Side Calculation Privacy

Our core mathematical tools—including our Factor Calculator, Quadratic Calculator, GCF Calculator, and polynomial tools—run entirely within your web browser using client-side JavaScript.

• The numbers, expressions, and equations you enter are processed locally on your device.
• We do not transmit, log, or store your mathematical inputs on any backend server.
• No user account or login is required to use any of our calculators.

2. Information We Collect

We collect personal information only when you choose to provide it directly:

• Contact Form Inquiries: If you contact us via our Contact Us page, we collect your name, email address, and message content solely to respond to your request.
• Voluntary Feedback: Any bug reports, tool suggestions, or comments you submit are used solely for website maintenance and customer support.

We do not sell, rent, or trade your contact information with third-party marketers.

3. Cookies & Local Storage

We use browser storage technologies strictly for functionality and user convenience:

For detailed information on how to review or reset these preferences, please read our dedicated Cookies Policy.

4. Third-Party Advertising & Google AdSense

We may display advertisements provided by third-party advertising partners, such as Google AdSense, to keep our calculators free for all users:

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
• Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites across the internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings.
• Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting www.aboutads.info.

5. Web Server Log Files

Like most web platforms, our hosting infrastructure automatically records standard log files when you visit our website. These files may include:

• Internet Protocol (IP) addresses
• Browser type and operating system
• Referring and exit pages
• Date and timestamp of visits

This data is used solely for technical administration, DDoS mitigation, detecting server errors, and safeguarding site security. It is not linked to personally identifiable information.

6. Data Retention and Security

Because calculations occur client-side, we store minimal data. Contact form messages are retained only as long as necessary to address your inquiry or maintain customer records. We implement reasonable administrative and technical security measures to prevent unauthorized access or disclosure.

7. Children's Privacy (COPPA Compliance)

Protecting the privacy of young learners is important to us. Factor Calculator provides educational mathematics tools suitable for general audiences and does not knowingly collect personal identifiable information from children under the age of 13. If you believe that a child has submitted personal details through our contact form, please notify us immediately so we can promptly delete the information.

8. Your Privacy Rights (GDPR & CCPA)

Depending on your jurisdiction (such as the European Economic Area, the UK, or California), you may have specific data rights:

• Right to Access: You can request a copy of any personal data you have voluntarily submitted to us.
• Right to Rectification: You can ask us to correct inaccurate or incomplete contact details.
• Right to Erasure: You can request that we delete your submitted contact records.
• Right to Non-Discrimination: We do not discriminate against users who exercise their privacy rights.

To exercise any of these rights, please reach out to us using the contact details below.

9. External Links

Our website and educational articles may contain links to external reference sites (such as Wikipedia or educational mathematics resources). We have no control over the privacy policies or content of external third-party sites and encourage you to review their respective privacy notices.

10. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect enhancements to our tools, legal requirements, or advertising practices. Any updates will be published on this page with a revised "Last updated" date.
