Privacy Policy
Effective Date: October 25, 2026
At Math.cgls ("we", "our", or "us"), we are deeply committed to protecting your privacy. This Privacy Policy outlines how your information is handled when you use our mathematical suite and web applications.
1. Information We Do Not Collect
Math.cgls operates primarily as a client-side computational environment. All graphing calculations, matrix operations, statistical regressions, and geometry constructions execute locally within your browser. We do not collect, store, or transmit your personal mathematical equations, datasets, or inputs to external servers.
2. Cookies and Local Storage
We may use local browser storage strictly to preserve your workspace preferences (such as calculator themes, recently active expressions, or session states). You can clear this data at any time through your browser settings. A shared graph link stores the expressions in the page address itself.
3. Third-Party Services
Our platform loads standard open-source UI libraries (such as Tailwind CSS and FontAwesome) via secure content delivery networks (CDNs). These providers may log standard diagnostic metadata (such as IP addresses) in accordance with their respective privacy policies.
4. Contact Us
If you have any questions or concerns regarding this Privacy Policy, please contact us at privacy@math.cgls.
Terms of Service
Effective Date: October 25, 2026
Welcome to Math.cgls. By accessing or using our website and mathematical software tools, you agree to be bound by these Terms of Service.
1. Acceptance of Terms
By using Math.cgls, you confirm that you accept these terms and agree to comply with them. If you do not agree, you must refrain from using our platform.
2. Permitted Use
Math.cgls is provided for educational, scientific, research, and professional computational purposes. You agree not to misuse our tools, attempt unauthorized access, or disrupt the platform infrastructure.
3. Intellectual Property
All software architecture, UI design, branding, and source code associated with Math.cgls are the intellectual property of Math.cgls Inc. All rights reserved.
4. Limitation of Liability
Math.cgls is provided on an "as is" and "as available" basis without warranties of any kind. Numerical results are approximations. We shall not be held liable for any computational inaccuracies, academic grading outcomes, or direct/indirect damages arising from the use of our calculators.
About Math.cgls
Math.cgls is a mathematical suite for students, educators, and anyone exploring a graph. Calculations stay in the browser.
The graphing workspace takes its interaction model from public calculator interfaces: an expression list, a keypad, graph settings, and a square grid you can zoom. The math engine, drawing, and interface are original to this project.
