Terms of Use

Using the tools

ZTool tools are free for personal and commercial use. You may not try to disrupt the site, scrape it at a rate that harms performance, or present our pages as your own.

No warranty

We work hard to keep every tool accurate, but all tools are provided "as is" without warranty of any kind. Financial, health and other calculators give estimates only. Check important results with a qualified professional before you act on them.

Limitation of liability

To the extent the law allows, ZTool is not liable for any loss arising from use of the site or reliance on its results.

Changes

We may update these terms from time to time. The date at the top of this page shows the latest revision.
