On SignHealth’s site we have removed almost all cookies. The ones that remain are necessary for the site to function properly.
For instance, when you click on ‘Okay, accept’ on the cookie notice, we use a cookie so that when you come back to the site you don’t get asked the same question every time. That cookie lasts for 120 days and then you will have to click ‘Okay, accept’ again.
You can disable all cookies on this site. The best way to do this is by using your browser’s controls. You can find out how to do that at the About Cookies website which offers guidance for all modern browsers.
