Welcome to Remainder Calculator. We are committed to protecting your privacy and ensuring a safe, transparent experience while you use our free Remainder Calculator and related educational resources. This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information.
1. Information We Collect
1.1 Calculator Data
Every dividend, divisor, quotient, and remainder you compute is processed entirely in your browser. We do not collect, transmit, or store any values you enter into the Remainder Calculator. Your numbers never leave your device.
1.2 Contact Information
If you reach out to us through our Contact Us page, we collect only the information you voluntarily provide, such as your name, email address, and message content. This information is used solely to respond to your inquiry and is not shared with any third parties.
1.3 Automatically Collected Information
When you visit our website, certain technical information may be collected automatically, including:
- IP address (anonymized where possible)
- Browser type and version
- Operating system
- Referring website URL
- Pages visited and time spent on our site
- Device type (desktop, tablet, mobile)
This data is collected through analytics tools and is used in aggregate to improve the performance and usability of the Remainder Calculator and our educational content.
2. How We Use Your Information
We use the information we collect to:
- Respond to your inquiries submitted via the contact form
- Analyze site traffic and usage patterns to improve the calculator
- Ensure the security and proper functioning of our website
- Improve the accuracy, animations, and educational content of the Remainder Calculator
- Develop new features (e.g., long-division view, batch calculations, modulo-vs-remainder comparison)
3. Cookies and Tracking Technologies
Remainder Calculator may use cookies and similar tracking technologies to enhance your experience. These include:
- Essential Cookies: Required for basic site functionality, such as remembering your preferred language setting.
- Analytics Cookies: Help us understand how visitors interact with the calculator, which features are most used, and where we can improve.
You can control cookie preferences through your browser settings. Disabling cookies may affect certain features of the website but will not impact the core calculator functionality — your dividends and divisors are processed entirely client-side regardless of cookie settings.
4. Third-Party Services
We may use the following third-party services:
- Google Analytics: To collect anonymized usage data and understand traffic patterns across our pages.
- Google AdSense / Ad Networks: To display relevant advertisements. These services may use cookies to serve ads based on your browsing activity.
- Google Fonts / Web Fonts: The Outfit, Inter, and JetBrains Mono fonts are loaded from external font CDNs.
These third-party services have their own privacy policies governing the use of your information. We encourage you to review their policies.
5. Data Sharing and Disclosure
Remainder Calculator does not sell, trade, or rent your personal information to third parties. We may share information only in the following circumstances:
- When required by law or to comply with legal processes
- To protect the rights, property, or safety of Remainder Calculator, our users, or others
- With service providers who assist in operating our website, subject to confidentiality agreements
6. Data Retention
Contact form submissions are retained only as long as necessary to resolve your inquiry. Analytics data is stored in anonymized, aggregate form and does not contain personally identifiable information. Calculator inputs (dividends, divisors, results) are never stored on our servers — not even temporarily.
7. Children's Privacy
Remainder Calculator is an educational tool suitable for users of all ages, including students learning about division, modular arithmetic, and number theory. We do not knowingly collect personal information from children under 13 years of age. If you believe a child has provided us with personal information, please contact us so we can promptly delete it.
8. Your Rights
Depending on your location, you may have the right to:
- Access the personal information we hold about you
- Request correction or deletion of your personal data
- Opt out of analytics tracking
- Withdraw consent for cookies at any time
To exercise any of these rights, please reach out through our Contact Us page.
9. Security
We implement appropriate technical and organizational measures to protect the limited information we collect. Our website uses HTTPS encryption to ensure secure data transmission. However, no method of internet transmission is 100% secure, and we cannot guarantee absolute security.
10. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
