What does our cookie do?

Our website uses cookies, as do almost all modern websites, to distinguish you from other users and remember you during your visit. These are sometimes called session cookies. This helps us to provide a good experience when you browse our website.  Our cookies:

  • Provide an anonymous code to distinguish you from other users

How to protect yourself from malicious cookies

When you transfer to an outside website, you are leaving the NASS domain, and NASS information management policies no longer apply. NASS encourages you to read the privacy statement of each external website that you visit before you provide any personal data.  Some of those sites may have tracking cookies that NASS does not control.

You can block cookies by activating the setting on your browser that allows you to refuse the setting of some or all cookies. We suggest consulting the Help section of your browser or visiting About Cookies website or The Security Skeptic which offer guidance for protecting modern browsers and operating systems. However, if you use your browser settings to block all cookies (including essential session cookies such as ours) you may not get full functionality from our website. By using the site you agree to our use of cookies.

It may be that your concerns of cookies relate to so called "spyware" and "tracking". Rather than switching off cookies in your browser you may find that anti-spyware software achieves the same end by automatically deleting cookies considered to be invasive.
