Terms of Use

Last updated: October 2026

By using this site you agree to the terms below. If you do not agree, please do not use it.

Use of the service

The tools are free to use for personal and commercial work. You may not use the site to process unlawful material, to attack or overload the service, or to resell access as your own product. Automated scraping that degrades availability is not permitted.

No warranty

The site is provided "as is". We make no guarantee that any tool is free of defects, that output is correct for your particular case, or that the service will be available at any given time. Use the output as a draft to verify, not as an authoritative result.

Calculators and financial figures

Tax, loan, payroll and severance calculators implement published rules as we understand them at the time of writing. Those rules change, and they vary by jurisdiction and by individual circumstance. Do not treat the output as tax or legal advice. Confirm any figure that matters with the relevant authority or a qualified professional.

Your content

You retain all rights to the files and text you process. We claim no licence over them. Because most processing is client-side, we generally never receive them at all.

Intellectual property

The site's own code, design and written guides are protected. You may quote short excerpts with attribution and a link. Republishing entire guides is not permitted.

Availability and changes

Tools may be added, changed or removed without notice. These terms may be updated; the date at the top of this page reflects the current version.

Limitation of liability

To the extent permitted by law, we are not liable for indirect or consequential loss arising from use of the site, including lost data, lost profit, or decisions made on the basis of a calculator's output.
