Cookie Policy


    Tessella is committed to privacy and security of information. This cookie policy provides information about what cookies ar, different types of cookies that we use and their purpose. Tessella performed a detailed cookie audit to present you with full details about our use of cookies.

    This information is given to you as part of our efforts to comply with recent legislation and to provide you with complete information about your privacy when using our website and other Tessella web applications.

    We use cookies to make our website easier for you to use. You can remove any cookies already stored on your computer, but this will lower the quality of your experience on our website.

    What cookies are

    Cookies are very small text files that are stored on your computer when you visit many websites. 
    The next time you go to the same website, your browser will send the cookie to the Web server. The message is sent back to the server each time the browser requests a page from the server. Since the Web server has no memory, the hosted website you are visiting transfers a cookie file to your computer so that the website can remember your preferences.

    There are different types of cookies. Some are technical cookies that help to improve your experience on a website. For example, remembering your username and password for your next visit or allowing you to navigate between pages efficiently. Other cookies may record the time of your visit, if you have been on the website before or if it’s your first visit, whether you have accessed the site directly or if you have been redirected from another source.

    Another important criterion is the time a cookie file is scheduled to stay on your computer. According to that, there are session cookies that will only be used throughout your visit and deleted when you close the browser, and persistent cookies. Persistent cookies will stay on your browser for the time period set within the cookie’s file and are reactivated when you revisit the website that created the cookie.
