Grades 1 through 10 math practice, lessons, progress, and games are local-first, free, and ad-free. No account is required for core learning.

Voice Coach and one-time known-friend battle codes require verified grown-up approval for each learner. Approval is scoped, expires from the device if credentials are removed, and can be withdrawn. There is no open matching, child search, chat, public ranking, or social feed.

Profiles provides grown-up approval, device-access removal, progress reset, and learner deletion. For assistance, contact support@mindmath.org or privacy@mindmath.org.
