Every cookie and script on Marathon Courses: what each one is for, who it's from, and how long it stays.
Your choice
The cookies the site needs to work are always on. Anything else waits for your yes if you’re in the EU, the UK or Switzerland. In California you can opt out of advertising at any time, and your browser’s Global Privacy Control counts as opting out. We keep your answer for a year, in a cookie of its own, and you can change it whenever you like.
Needed to work
Always on. Without these, your basket, signing in and your cookie choice wouldn’t work. None is used to follow you.

Other companies’ pages
Checkout and the sign-in code are on Shopify’s pages, and the course is on Kajabi’s. Each sets its own cookies there, under its own privacy policy. Our own scripts on those pages follow the choice you make here.
