Privacy Policy

Welcome to CalcSolver ("we", "our", or "us"). We are committed to protecting the privacy and personal data of our users, particularly students, educators, and lifelong learners. This Privacy Policy explains what information we collect, how it is used, and the steps we take to protect your data when you visit CalcSolver and use our online mathematical calculation tools.

By using CalcSolver, you acknowledge that you have read and understood this Privacy Policy. If you disagree with any part of this policy, please discontinue use of our website.

CalcSolver is built on a privacy-first, client-side architecture. You are never required to create an account, register, or provide personal credentials to use our calculation tools.

• Client-Side Calculation Data: Mathematical equations and inputs you type are processed locally in your browser via JavaScript. We do not store or transmit your inputs to external servers.
• Local Storage: We use your browser's localStorage solely to save client-side preferences (chosen Light/Dark theme, calculator history). This data resides entirely on your device and can be cleared at any time.
• Anonymous Usage & Analytics: We may collect non-identifiable, aggregated technical data (such as browser type, device category, screen resolution) to monitor server performance and improve tool accessibility.

CalcSolver does not use intrusive tracking cookies, fingerprinting, or cross-site behavioral tracking scripts. We may use standard functional cookies strictly required for cloud caching and CDN security (such as Cloudflare DDoS protection).

• No third-party advertising cookies are placed on your device.
• No behavioral remarketing or retargeting scripts are present.
• You may clear all cookies at any time through your browser settings without affecting core tool functionality.

Protecting children's online privacy is of utmost importance. CalcSolver complies with the Children's Online Privacy Protection Act (COPPA) and the Family Educational Rights and Privacy Act (FERPA):

• We do not knowingly collect, solicit, or maintain personally identifiable information from children under the age of 13.
• Our tools do not require student email addresses, names, phone numbers, or account registrations of any kind.
• No calculation inputs are stored on our servers or linked to any student identity.
• If you believe a child has inadvertently submitted personal information, please contact us immediately and we will promptly remove it.

Our website may contain links to external educational resources or documentation. We are not responsible for the privacy practices or content of third-party websites. We encourage you to read the privacy statements of every website you visit.

We implement industry-standard security safeguards to protect our platform and its users:

• HTTPS 256-bit SSL encryption for all web traffic between your browser and our servers.
• Modern content security headers (CSP, HSTS, X-Frame-Options) to prevent injection attacks.
• Secure Cloudflare edge infrastructure for DDoS mitigation and asset integrity.
• No user-submitted data is stored in a backend database, eliminating data breach risk.

We may occasionally update this Privacy Policy to reflect improvements to our platform or changes in legal regulations. Any updates will be posted on this page with an updated revision date at the top.

We encourage you to periodically review this page for the latest information on our privacy practices.

If you have questions, feedback, or privacy concerns, please reach out via our Contact Page or email us directly at [email protected]. We aim to respond to all privacy inquiries within 48 hours.
