You are responsible for the accuracy and completeness of inputs, the interpretation of outputs, and every decision or action taken. Independently verify important results, formulas, classifications, rates, dates, supplier evidence, commercial terms, and applicable requirements with qualified people and authoritative sources.

You may use the site for lawful internal or personal analysis. Do not misuse it, interfere with its operation, attempt unauthorized access, introduce harmful code, or use it to violate rights, contracts, procurement policy, sanctions, law, or regulation.

No warranties

To the fullest extent permitted by law, the site and tools are provided “as is” and “as available,” without warranties or conditions of any kind, express or implied, including accuracy, completeness, availability, reliability, merchantability, fitness for a particular purpose, title, or non-infringement.

Limitation of liability

To the fullest extent permitted by law, the site operator will not be liable for indirect, incidental, special, consequential, exemplary, or punitive loss, or for lost profits, revenue, savings, data, opportunity, goodwill, production, or business interruption arising from use of or inability to use the site. Where liability cannot lawfully be excluded, it is limited to the minimum extent permitted. Nothing in these terms excludes or limits rights or liability that cannot legally be excluded or limited.
