Using the tools.
You may use the tools for lawful personal planning, checking example arithmetic and a just-for-fun quiz without a fee or account. Use the documented input formats and work-size limits.
Your assumptions.
Choose costs, capacities, rates, time periods and currency relevant to your intended scenario. Read the method and check important figures independently. Defaults are examples and should be replaced where necessary.
Privacy and chosen copies.
Keep notes non-identifying and do not submit credentials, tokens or private records. You control text, PDF and printed copies you choose to keep or share. Browsers, email, hosting and other installed software may handle information separately, as explained in Privacy Policy.
Acceptable use.
