Terms of use

Version dated September 21, 2026

MozgoQuest provides free problems and practice for grades 1–5. An adult creates the account, is responsible for creating and using a linked child profile, and confirms consent to process the minimum child data described in the privacy notice. Do not enter a child’s full name or share a password with other people.

The project’s problems are available for personal learning. If you want to use the materials publicly or find an error in an answer, email hello@mozgoquest.com. The site is not an official resource of any competition organizer.

We may correct problem statements and answers and continue developing the site. Previously saved answers remain connected to earlier versions of a problem. An adult can download or delete family data from the dashboard. See Privacy and data and Contact for details. The site does not currently accept payments.
