Cuadrivio is an information-society service within the meaning of Spain's Law 34/2002 (LSSI-CE): a website offering a mathematics calculator and course material, free of charge and without registration.

The worked solutions and the software that produces them belong to the operator named above, except where another owner is identified. The open-source components the site is built on keep their own licences.

The operator takes care that the material is correct, but does not warrant that it is free of error and is not liable for the use made of it. The terms of use set out what that means in practice.

Spanish law applies. Any dispute goes to the courts having jurisdiction under the applicable rules, which in the case of a consumer are those of their own place of residence.

Questions about any of this, or about a stored problem: contact@cuadrivio.app
