How CardGrade.io uses cookies and similar technologies — and how to control them.
Last updated: June 22, 2026
Cookies are small text files stored on your device. We use cookies and similar technologies (such as the Meta Pixel) for three purposes: to make the site work, to understand how it is used, and — with your permission — to measure advertising.
When you first visit, we ask for your choices. In the EEA, UK, Switzerland, Canada, and Brazil, analytics and advertising cookies stay off until you accept. In the United States and elsewhere they run by default and you can opt out at any time. We also honor the Global Privacy Control (GPC) browser signal. You can change your mind whenever you like using the button above or the “Cookie Preferences” link in our footer.
Required for the site to work — sign-in, security, and remembering your privacy choices. These cannot be switched off.
