Terms of Use

Effective August 19, 2026

Use of the tools

ToolPorch's tools are free to use for personal, educational, and commercial work. Don't scrape, clone, or resell the site itself, and don't use it to do anything illegal. That's most of it.

Accuracy and professional judgment

We document each calculator's method on its page and work to keep every computation correct. However, the tools are provided as-is, without warranty of any kind. They are calculators, not professional advice: evaluation timelines are governed by your state's regulations, test-age conventions by your assessment's manual, and pricing decisions by your business. Verify results that carry professional or legal consequences. ToolPorch and its operators are not liable for decisions made in reliance on a computed result.

Local storage

Some tools save data (class lists, settings) in your browser's local storage for your convenience. That data lives on your device; we can't access or recover it. Clearing browser data deletes it.

Advertising

The site is supported by third-party ads on regular pages. Ad content belongs to the advertisers; an ad's appearance here isn't an endorsement.

Changes

We may update these terms; the effective date above reflects the current version. Continued use after a change means acceptance. Questions: [email protected].
