Privacy Policy

1. Information We Collect

Matrix Inputs: All matrix computations run entirely in your browser. Your matrix data is never sent to our servers and we have no access to it.

Usage Data: We collect standard web server logs including IP addresses, page URLs, browser type, and timestamps. This data is used only for site performance monitoring and security.

Cookies: We use minimal cookies for site functionality (e.g., remembering your daily challenge streak). We do not use tracking cookies or cross-site tracking technologies.

Local Storage: The problem of the day streak counter is stored in your browser's localStorage. This data stays on your device and is never transmitted to us.

2. How We Use Information

• To serve and improve our website
• To analyze aggregate usage patterns (no individual tracking)
• To respond to contact form submissions
• To maintain security and prevent abuse

3. Third-Party Services

We load the following third-party resources from CDNs:

• KaTeX (math rendering) — from cdn.jsdelivr.net
• math.js (computation library) — from cdn.jsdelivr.net

These CDNs may log your IP address when loading these resources, per their own privacy policies.

4. Data Sharing

We do not sell, trade, or transfer your personal information to any third parties. We do not use advertising networks that track individual users across sites.

5. Data Security

Our website is served over HTTPS. Since matrix computations run client-side, there is no server-side storage of your calculations.

6. Your Rights

You may contact us to request deletion of any personally identifiable information we may hold (e.g., if you contacted us by email). Contact: contact@MatrixSolverPro.com

7. Children's Privacy

Our site is suitable for all ages. We do not knowingly collect personal information from children under 13.

8. Changes to This Policy

We will post changes to this policy on this page with an updated revision date.
