What are cookies and how do they work?
A cookie is a text file containing information that can be remembered by a web browser between pages. When an individual uses a web browser to access the internet their browser can create cookies which are stored on the user’s computer. Cookies are not programs and therefore cannot contain viruses or other malicious software. They are purely a string of text and numbers.
Session cookies only last during a single visit. When you close your web browser the session cookie information is automatically removed from your computer.
Persistent cookies are stored by the user's web browser even when the web browser has been closed, so that the next time a user goes back to the website that originally set the cookie, the web site can read information back from the cookie.
Persistent cookies have an expiry date which controls when they are automatically deleted. This can be anything from a few minutes to several years, depending on your own browser settings.
The Eyenetwatch website uses session cookies for two purposes:
Two session cookies are set that temporarily store a unique identifier for each visitor to the website. This identifier is a random series of letters and numbers and doesn't contain any personal or identifiable information. It is used to help count the number of visitors to the Eyenetwatch website.
Two cookies are set by the computer systems that run the Eyenetwatch website. These cookies are used as part of the process of sending web pages to the user's web browser and are essential - no website using Microsoft technology will work without these cookies.
Eyenetwatch use persistent cookies for the following purposes:
Eyenetwatch use their own cookies to remember which items a customer has put into their basket. By using a persistent cookie for this, a customer can close their web browser and come back to the Eyenetwatch website subsequently and still be able to access items that had been put into their shopping basket on a previous visit. This cookie is essential for the functioning of the Eyenetwatch website as without it customers would be unable to place items into the shopping basket. The cookie lasts for 1 year but is cleared once an order has been placed.
Eyenetwatch also use a cookie to remember a user's website preferences such as preferred language, currency and delivery country. The first time a customer visits the Eyenetwatch website they are asked to confirm this information which is then stored in a cookie set to last for 1 year. Without this cookie the customer would have to re-enter their preferences every time they visit the website.
A number of persistent cookies are also set by the computers that run the Eyenetwatch website. These cookies are solely used to record technical information necessary for our web servers to work properly. No personally identifiable information in stored in these cookies.
