Document handling
Private by design.
For document-analysis tools, text is processed in your browser. clauseInsight.com does not intentionally upload document contents to a clauseInsight.com server for analysis. PDF parsing software is loaded only when required; the document itself remains in the browser for extraction and analysis.
FAQ
Useful answers, before you start.
clauseInsight.com is designed to be transparent about what each tool does—and what it does not do.
Does this detect the dates from my contract?+
No. This calculator uses the dates and periods you enter. Use the Red-Flag Checker to help surface renewal or notice language in document text.
What if the contract uses business days?+
The current renewal calculator uses calendar periods. Review the contract wording if a deadline is specifically stated in business days.
Can month-end dates shift?+
JavaScript calendar arithmetic follows calendar rules and can roll dates when a target month has fewer days. Always compare the result with the contract’s exact wording.
