Electronic privacy & the use of ‘cookies’

Technology 06/07/2012

The E-Privacy Directive (2009/136/EC) was transposed into law in Ireland with the enactment of the European Communities (Electronic Communications Networks and Services) (Privacy and Electronic Communications) Regulations 2011, which took effect on 1 July 2011. Regulation 5(3) deals, among other things, with the storage and retrieval of information on 鈥榯erminal equipment鈥, most commonly a computer user鈥檚 browser.

Modern browsers have different mechanisms of data storage on a visitor鈥檚 machine, the most common method being via the use of 鈥榗ookies鈥.

A cookie is a small file on the computer鈥檚 hard drive that stores pieces of text. A browser can set and collect information from this text file when a visitor enters a website. A cookie might report back to the originating website details of when you last visited their site, or the number of times you visited, or details of your browser鈥檚 history.

Many law firms facilitate the implementation of cookies on their websites when using the Google Analytics system of tracking visitors to their home page. Social media widgets also are known to set cookies. The 2011 regulations require that consent to the placing of cookies should be obtained and that a website should offer 鈥渃lear and comprehensive information鈥 in connection with the information being collected.

The 2011 regulations do not specify that prior consent needs to be obtained. Therefore, we would recommend that, if your website uses cookies, you should, at a minimum:

  • Include a link to your privacy policy on all pages,  
  • Explain in that policy document how and why you use cookies, stating, for example, that the firm uses cookies to count visitors to your website (if that is the case),  
  • Detail how, if a visitor chooses to accept cookies, they also have the ability to later delete cookies that they have accepted. For example, in Internet Explorer 9, cookies can be deleted by selecting 鈥榠nternet options鈥 and, under the 鈥榞eneral鈥 tab, selecting the heading 鈥榖rowsing history鈥 and then selecting the 鈥榙elete鈥 button. Finally, tick the 鈥榗ookie option鈥 and click 鈥榙elete鈥.
