3. Collection And Use Of Information Using Cookies.

As with many state-of-the-art Internet sites, the Site uses “cookies” to enhance the functionality of the Site and to make transactions and other activities more convenient and efficient for Members, Contributors, Users or Clients. A “cookie” is a file stored locally on computers used to access the Member, Contributor, User or Client account that contains information relating to a Member, Contributor, User or Client's past use of the Site. For example, a cookie may contain information previously entered on a Site form, which may be recalled as default information when that form is accessed at a later time. This prevents re-entry of frequently used information each time a Member, Contributor, User or Client account is accessed. Cookies are also useful in streamlining log-in and in preserving transactional information between sessions. Cookies will likely play an increasingly important role as we enhance the ability of Members, Contributors, Users or Clients to customize the functionality of the Site to better meet their needs and preferences. Most Internet browsers include preference settings that allow users to be notified and control whether cookies are transferred to their computers. Please review Your browser's documentation or “help” feature for more information on that functionality. Although disabling cookies will not affect a Member, User or Client's ability to transact business on the Site, it may make such activities more time consuming.

Hdac Technology AG is not responsible for and cannot make any assurances regarding privacy, or other policies or practices of the operators of such websites.
