Use of the tools
The tools on util·tools are free to use for personal and commercial purposes. You do not need permission to use a result you produced with them — the output of a calculation belongs to you.
No warranty
The tools are provided as they are, without warranty of any kind. We test the calculations and fix errors when we find them, but we cannot guarantee that every result is correct for every input or suitable for your particular purpose.
This matters most where a number carries consequences. Do not rely on this site alone for a legal deadline, a tax figure, a medical dose, an engineering tolerance, or any decision where being wrong is costly. Check the result against an authoritative source for that field.
Availability
We aim to keep the site up but do not promise uninterrupted service. Tools may be changed, renamed or removed. Pages that move are redirected where practical.
Your responsibilities
Do not use the site to break the law, to attack the service or its users, or to scrape it in a way that degrades it for others. Automated bulk use that affects availability may be blocked.
Liability
To the extent permitted by law, we are not liable for loss arising from use of the site or reliance on its output, including lost profits, lost data or consequential damages.
Changes
These terms may change. Continued use after a change means you accept the updated terms. Related pages: Privacy Policy and Disclosure.
