Cookies are small files a website stores on your device. MathSkills4Kids uses as few as possible. This page lists every cookie we use, grouped the same way as in our cookie choices panel. For how we handle personal information in general, see our Privacy Policy.
Children never see ads
When a child is signed in (through a parent, teacher or class code), we show no ads and no cookie banner, and we only use the necessary cookies below. We never use advertising cookies to target children.

Visitors in the European Economic Area, the UK and Switzerland
In these regions your choice is collected by Google's certified consent tool (IAB Transparency & Consent
Framework). Google stores that choice in its own cookies (such as FCCDCF and FCNEC, up to
13 months). If you refuse advertising cookies, Google may still show limited, non-personalized ads that do not
use cookies. Elsewhere, our own cookie banner records your choice in the ms4k_consent cookie.
Free games and free worksheets are paid for by ads. If you are in these regions, not signed in, and refuse cookies, we ask you to accept cookies or choose Premium before playing or downloading for free.
Changing your choice
You can change your mind at any time: use Manage cookies at the bottom of every page. You can also delete cookies in your browser settings; we will then ask again. We ask again automatically after 6 months.
