Strictly necessary
Where advertising runs, a record of your consent choice, so you are not asked on every page. Set by Google's consent message, and required for the consent mechanism itself to work. Without advertising there is no consent choice to record, and no cookie at all.
Advertising and analytics
Set only where advertising is running. These are third-party cookies from Google, used to select and measure advertising. In the European Economic Area, the United Kingdom and Switzerland they are set only after you consent; elsewhere Google sets them under its own terms, and you can opt out in Google's Ads Settings at adssettings.google.com. No analytics cookie is set, because the site runs no analytics.
Declining leaves the site fully functional. Where advertising is shown to a visitor who has declined, it is non-personalised — chosen from page context rather than from anything about you.
Save with Google
If you press Save with Google, a Google sign-in window opens from google.com. That window is Google's page, and Google may set its own cookies there, under its own terms. This site sets no cookie for it. It keeps one yes-or-no entry in your browser's storage saying that you connected before, so the button can offer to reconnect; your Google sign-in itself is held in the page's memory only.
Changing your mind
Where advertising runs, the Cookie preferences link in the footer reopens the consent panel at any time. You can also clear cookies and site data in your browser, which resets both the consent record and everything the site had remembered.
