Quick view.Strictly necessary cookies (auth, payment, your active child) load automatically — they're essential. Analytics are off until you opt in. We don't currently use any advertising/marketing cookies.

What are cookies?

Cookies are small text files a website stores in your browser. Some are essential (without them you can't stay signed in or check out). Others are optional — measuring how the site is used, or showing you relevant ads on other sites.

How to change your choices

Children

Strictly necessary cookies still apply when an adult is signed in to use the service with a child. We don't set advertising or behavioural-tracking cookies on accounts at any time, regardless of consent state.
