Route 09.02 / Functional categories
Cookie use categories
These categories describe the functional reasons cookies or similar technologies may be used on the website. They are intended to make the purpose of each category easier to scan without suggesting that every visitor encounters every technology.
Essential
Strictly necessary functions
Some cookies or similar storage may be needed to support core website functions, security, navigation continuity and the reliable delivery of pages you request. These functions may be necessary for the site to work as intended in your browser. If they are blocked, limited or removed, parts of the website may not operate consistently, even where the information on a page remains available to read.
Preferences
Preference functions
Some technologies may remember visitor choices, such as display or interaction preferences, so a repeat visit can feel more consistent. Examples are illustrative only: a particular feature may or may not be available at a given time. Preference functions are distinct from technologies needed for essential site operation, and their use can depend on the pages or services you choose to access.
Performance
Performance and measurement functions
Technologies may help the website understand technical performance, page reliability and aggregate use patterns so it can be maintained and improved. This can include checking whether pages are delivered effectively or identifying areas that need technical attention. This policy does not state that identifiable visitor profiles are built, and the use of a performance function may depend on the feature or page being used.
External services
Embedded or third-party services
When the site includes or links to an external service, that service may set or read cookies or similar technologies under its own policies and controls. Luck and Marble may not control every technology used by an external provider. Where relevant, you should review the information supplied by that provider to understand its practices and the choices it makes available for its own service.
Category availability note. These categories describe possible functional purposes. The exact cookies or similar technologies involved can depend on the pages, features and services you use, as well as the browser and device settings you have chosen.
