You may use the calculators for learning, homework, teaching demos, and everyday math. You agree not to misuse the site. That includes trying to break security, overload the servers, scrape the site in a harmful way, copy the service for resale without permission, or use the tools in a way that breaks the law or school exam rules.

Certain features use third-party open source software. The graphing calculator uses function-plot under the MIT License. Math evaluation uses mathjs under the Apache License 2.0. Your use of those components is also subject to their license terms. Full notices are on the Open Source Licenses page.
