Countopus is provided free of charge, in full. There is no subscription, no in-app purchase and no paid content. We do not ask for payment details and we have no payment relationship with you.

Who may use it

The app is designed for children, and is intended to be installed and supervised by a parent, guardian or teacher. A grown-up should set it up and decide when it is used.

Your child's data

We collect no personal information. Learning progress is stored on the device and is never uploaded. See the privacy policy for the detail.

Educational content

The lessons follow widely used K–5 mathematics practice, but the app is a learning aid and not a substitute for schooling or professional educational assessment. We make no guarantee of any particular learning outcome.
