By using Okane Keisan, you are deemed to have agreed to these terms.
The service
Okane Keisan provides free calculation results based on what you enter and on public data (tax rates, deductions and so on; see the Sources section of each calculator). The tools are provided for general information.
Not professional advice
Nothing on this site is tax, legal, financial or investment advice. Results are estimates and may not reflect your own circumstances (which deductions apply, differences between local governments, law changes after the date shown on the page, and so on). Consult a professional for your own situation. This site is general information, not tax, legal, or financial advice.
No warranty
The site and the calculators are provided “as is”, without warranty of any kind, including accuracy, reliability or fitness for a particular purpose. We check figures against primary sources wherever possible, but we do not guarantee that they are free of errors.
Limitation of liability
To the maximum extent permitted by law, Okane Keisan is not liable for any damage arising from the use of the site or the calculators.
Prohibited conduct
You must not interfere with other users' use of the site, collect data automatically beyond normal use (scraping and the like), or act in violation of applicable laws.
Changes to these terms
These terms may be updated as the site changes. By continuing to use the site, you are deemed to have agreed to the latest terms.
These terms are a general template and not legal advice. Depending on your business and jurisdiction, have a lawyer review them before relying on them.
