Terms of Use
The terms you accept by using this site — in plain language.
What you are agreeing to
By using this site you accept these terms. They exist to set honest expectations, not to trap anyone: the tool is free, your data stays on your device, and the few rules below are the kind any reasonable person would expect.
The service
This site and its tool are provided free of charge and as-is. We work hard to make the tool correct — its logic is tested against known-good reference values — but we cannot warrant that every result is accurate for every purpose, and you use it at your own risk.
Sensible-use rule
Do not rely on this tool alone for a decision with legal, financial, medical or safety consequences. For anything that matters, verify the result against a second source. If you ever get a result that looks wrong, please tell us — we treat correctness reports as the highest-priority kind of feedback.
Your content and output
Whatever you type into the tool remains yours. The tool's output is yours to use freely, including commercially — no attribution required.
Our content
The articles and guides on this site are written for this site. You may quote them with a link to the source; wholesale copying is not permitted.
Acceptable use
Do not attempt to disrupt the site, scrape it at abusive rates, or use it in a way that harms other visitors' ability to use it.
Liability
To the maximum extent permitted by law, we are not liable for losses arising from the use of, or inability to use, this site or its results.
Changes
If these terms change, the updated version will be published on this page with no retroactive effect. Questions: hello@lesco-bill.net.
