This Cookie Policy explains what cookies are, which cookies QR Node uses, why we use them, and how you can manage your preferences. It supplements our Privacy Policy.
Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work efficiently, remember your preferences, and provide analytical information to website owners. Cookies cannot run programs or deliver viruses to your device.
We group cookies into three categories. You can manage Functional and Analytics cookies via the cookie banner or at any time through your browser settings. Essential cookies cannot be disabled as the site would not function without them.
These cookies are strictly necessary to provide the core service. They enable authentication, session management, and security features. Without them the site cannot function.
