Cookie Policy

In order for this site to work properly and to evaluate and improve the site, we and other organisations may collect information by using small files and other tracking technologies on your computer (for simplicity we refer to all such technologies as “cookies”). Over 90% of all websites do this. By continuing to use this site, you agree to us and third party organisations using cookies as described below. You can opt out of the use of cookies by following the links below, though please bear in mind that if you do the performance and your enjoyment of our site may be affected. There are a variety of cookies used on the at800 and DMSL websites, mostly to improve the user experience and help us tailor content to user needs.

What are cookies?

Cookies are tiny text files that are stored on your computer, tablet or mobile phone when you visit a website. The cookies mean that the website will remember you and how you’ve used the site every time you come back.

How we use cookies?

We use Google Analytics to track anonymous data about visitors that use our site. This is in order to help us improve usability and deliver relevant content. If you are not comfortable with this in any way we advise you to refrain from using the website.

What cookies are in place?

Google Analytics

  • ‘__utma’ – This keeps track of the number of times a visitor has been to the site, when their first visit was, and when their last visit occurred. (The record of visits is deleted after two years).
  • ‘__utmb’ – A timestamp of the exact moment in time when a visitor enters the site. (Expires after 30 minutes).
  • ‘__utmc’ – A timestamp of the exact moment in time when a visitor leaves the site – having waited 30 minutes for another pageview to happen, and if it doesn’t, it expires. (Expires at the end of the session).
  • ‘__utmz’ – This keeps track of where the visitor came from, what search engine was used, what link was clicked on, what keywords used, and where in the world the site was accessed from. (Expires after six months).

When you visit the at800 or DMSL website, your visit is tracked as a session. A Google Analytics user ID code is generated at each session. DMSL will disassociate the user ID from the session after 14 months. More information on the cookies set by Google Analytics and how to opt out are on the Google Analytics website – Click Here.


  • ‘__atuvc’ – The __atuvc cookie is created and read by the AddThis social sharing site JavaScript on the client side in order to make sure the user sees the updated count if they share a page and return to it before our share count cache is updated. No data from that cookie is sent back to AddThis and removing it when disabling cookies would cause unexpected behavior for users. (Expires after two years).

If you do decide to disable or delete them altogether some sites will not work as well as they rely on cookies to provide you with the service you have requested.
