Cookie Policy

What Is A Cookie?

A cookie is a piece of information in the form of a very small text file that is placed on an internet user’s hard drive. It is generated by a web page server, which is basically the computer that operates a web site. The information the cookie contains is set by the server and it can be used by that server whenever the user visits the site. A cookie can be thought of as an internet user’s identification card, which tell a web site when the user has returned.

What Is The Purpose Of Cookies?

Cookies make the interaction between users and web sites faster and easier. Without cookies, it would be very difficult for a web site to allow a visitor to fill up a shopping cart or to remember the user’s preferences or registration details for a future visit.

Web sites use cookies mainly because they save time and make the browsing experience more efficient and enjoyable. Web sites often use cookies for the purposes of collecting demographic information about their users.

Cookies enable web sites to monitor their users’ web surfing habits and profile them for marketing purposes (for example, to find out which products or services they are interested in and send them targeted advertisements).

Cookies come in different flavours:

Session, Or Transient Cookies

Cookies that are stored in the computer’s memory only during a user’s browsing session and are automatically deleted from the user’s computer when the browser is closed.

These cookies usually store a session ID that is not personally identifiable to users, allowing the user to move from page to page without having to log-in repeatedly. They are widely used by commercial web sites (for example, to keep track of items that a consumer has added to a shopping cart).

Session cookies are never written on the hard drive and they do not collect any information from the user’s computer. Session cookies expire at the end of the user’s browser session and can also become no longer accessible after the session has been inactive for a specified length of time, usually 20 minutes.

Permanent, Persistent, Or Stored Cookies

Cookies that are stored on the user’s computer and are not deleted when the browser is closed. Permanent cookies can retain user preferences for a particular web site, allowing those preferences to be used in future browsing sessions.

Permanent cookies can be used to identify individual users, so they may be used by web sites to analyse users’ surfing behaviour within the web site. These cookies can also be used to provide information about numbers of visitors, the average time spent on a particular page and generally the performance of the web site. They are usually configured to keep track of users for a prolonged period of time, in some cases many years into the future.

Flash Cookies

If you have Adobe Flash installed on your computer (most computers do), small files may be stored on your computer by websites that contain Flash media, such as video clips. These files are known as Local Shared Objects (LSOs) or Flash cookies. They can be used for the same purposes as regular cookies (properly called HTTP cookies).

Flash cookies can also back up the data that is stored in a regular cookie. When you delete cookies using your browser controls, your Flash cookies are not affected. So a website that served a cookie to you may recognise you on your next visit if it backed up its now-deleted cookie data to a Flash cookie.

You can control Flash cookies. Adobe’s website offers tools to control Flash cookies on your computer and users of the Firefox browser can also get anadd-on to detect and delete Flash cookies.

Are Cookies Dangerous?

No. Cookies are small pieces of text. They are not computer programs, and they can’t be executed as code. Also, they cannot be used to disseminate viruses, and modern versions of both Microsoft Internet Explorer and Netscape browsers allow users to set their own limitations to the number of cookies saved on their hard drives.

Can Cookies Threaten Users’ Privacy?

Cookies are stored on the computer’s hard drive. They cannot access the hard drive – so a cookie can’t read other information saved on the hard drive, or get a user’s e-mail address etc. They only contain and transfer to the server as much information as the users themselves have disclosed to a certain web site.

A server cannot set a cookie for a domain that it is not a member of. In spite of this, users quite often find in their computer files cookies from web sites that they have never visited. These cookies are usually set by companies that sell internet advertising on behalf of other web sites. Therefore it may be possible that users’ information is passed to third party web sites without the users’ knowledge or consent, such as information on surfing habits. This is the most common reason for people rejecting or fearing cookies.
