Terms of use

Tools are supplied for general information and preliminary estimates. Check local unit conventions, rates, dates, sizing charts and provider terms before relying on any result. No guarantee is made that estimates suit every situation.

Health tools are educational screening estimates for adults, not medical advice. General adult tools are not designed for children or clinical management. Pregnancy and cycle tools provide educational estimates only; consult a qualified clinician for care and dating. Consult an appropriate professional for personalised advice.

You may use these tools for ordinary personal or business calculations. Do not disrupt the service or attempt unauthorised access.
