The Evigrade extension and cookies
The Evigrade browser extension does not set cookies. All settings (stop-list, comparison list, anonymous install id) are stored in the browser's local storage (chrome.storage), which is not shared across sites.
Managing your choice
You can change your consent at any time – clear the site's localStorage or reset your consent (the banner will reappear). You can delete cookies in your browser settings.
