Intellectual Property & Proprietary Rights

Proprietary Platform Assets & Software Ownership

As specified in these FactorCalc terms of service, all intellectual property rights in and to the Platform—including but not limited to the FactorCalc brand, logo, domain names, custom SVG icons, front-end architecture, CSS stylesheets, JavaScript calculation logic, editorial tutorials, worked mathematical examples, and formula cheat sheets—are and shall remain the exclusive property of FactorCalc and its licensors.

Fair Educational Attribution & Quoting Guidelines

Fair Educational Attribution: Educators, textbook authors, and academic researchers may quote short instructional excerpts or cite worked steps from FactorCalc for educational purposes, provided that prominent attribution and an active hyperlink to `https://factorcalc.org` are maintained.

Disclaimer of Warranties & Mathematical Accuracy (Educational Aid Notice)

“As-Is” and “As-Available” Statutory Disclaimer

PLEASE READ THIS SECTION CAREFULLY, AS IT LIMITS OUR LIABILITY TO THE MAXIMUM EXTENT PERMITTED BY LAW.

1. ‘AS IS’ and ‘AS AVAILABLE’ Provision: FactorCalc and all associated content, calculation outputs, step-by-step derivations, and reference formulas are provided on an “AS IS” and “AS AVAILABLE” basis, without warranties of any kind, whether express, implied, statutory, or otherwise. We explicitly disclaim all implied warranties of merchantability, fitness for a particular educational purpose, title, and non-infringement.

Mathematical Modeling & Edge-Case Limitations

1. Mathematical Accuracy & Rigor: While every mathematical algorithm on FactorCalc is engineered in accordance with rigorous academic standards and verified continuously across an automated test harness of 355 unit tests, mathematics is an expansive field encompassing infinite edge cases. We do not warrant that our calculation results or derivations will be 100% accurate, uninterrupted, timely, or completely error-free under all theoretical conditions.

Mandatory Independent Verification for Critical Engineering or Finance

1. Mandatory Independent Verification: FactorCalc is designed strictly as a supplementary educational study aid and learning companion. It must NEVER be relied upon as the sole or primary calculation authority for life-critical structural civil engineering, aerospace ballistics, medical dosages, financial audits, legal calculations, or official examination grading without independent human verification through authoritative, peer-reviewed mathematical literature.

Limitation of Liability

Exclusion of Indirect & Consequential Damages

To the fullest extent permitted by applicable law, in no event shall FactorCalc, its founders, reviewers, or hosting providers be liable for any indirect, incidental, special, consequential, or punitive damages—including without limitation loss of academic credit, lost study time, exam performance outcomes, data loss, or server downtime—arising out of or in connection with your access to or inability to use the Platform.

Aggregate Liability Cap

In jurisdictions that do not allow the exclusion of certain warranties or limitations of liability, FactorCalc’s aggregate liability shall be strictly limited to the fullest extent permitted by law, not to exceed the amount of fifty United States dollars ($50.00).

Third-Party Services, External Links & Advertisements

Hyperlinks to External Educational Authorities

FactorCalc contains hyperlinks to external third-party educational authorities (such as Wolfram MathWorld, OpenStax, and W3C) and displays advertisements served by third-party ad networks including Google AdSense. These external resources and advertisements are provided solely for educational reference and platform sustainability.

Google AdSense Network Disclosures

FactorCalc does not endorse, control, monitor, or assume any legal responsibility for the content, privacy practices, terms of service, or accuracy of third-party websites or advertisements. Accessing external links is undertaken entirely at your own discretion and risk.
