Optional analytics and marketing tags require a separate choice. Rejecting optional tags does not stop the feeding charts, calculators or product pages from working.

Optional services
If Google Analytics is configured, analytics consent controls whether its tag is loaded. If the Meta pixel is configured, marketing consent controls whether its tag is loaded. The cookie inventory must be checked against the actual configured services and browser behaviour before launch.
Change your choice
Use Privacy settings in the footer. You can accept or reject each optional category. Clearing browser storage also removes saved preferences. After withdrawing consent, this site stops optional event tracking and attempts to remove its accessible analytics and marketing cookies.
Other sites and fonts
Regional stores have their own cookie notices. This site loads fonts from Google Fonts. Your browser contacts that provider when fetching those font files.
