Clear guide through European cookies laws

What are cookies

A cookie is a small file that is sent by a website and stored on the user's browser so that the website can view the user‘s previous activity.

Each time a user enters a website, the browser sends the cookie to the server to notify the site about their previous activity. We can say that they basically give a website the ability to differentiate users and act accordingly.

Types of cookies

  • First or third party cookies
  • Session or persistent cookies
  • Technical cookies
  • Customization cookies
  • Analysis cookies
  • Rack cookies
  • Behavioral advertising cookies

What are cookies for

Cookies were designed to be a mechanism to remember different types of information, such as products of a shopping cart in an online store, user activity, which websites you previously visited, what buttons you have pressed, etc...

Dangers resulting from the use of cookies

Although cookies can not contain a virus and can not install malware on the user's computer, tracking and monitoring cookies, especially third-party cookies are able to collect long-term records of user navigation on the Internet. Cookies can also store passwords and form data that a user has entered, such as a credit card number or address.

Security depends on the user's browser and the security systems used by the web which originates the cookie. In extreme cases, a hacker can access the cookies and use the information they may contain, such as data access so he can impersonate a user and gain access on the web page that originates the cookie.

Cookies privacy concerns

Online advertising companies use cookies to track users that have visited the web pages where they have placed their ads so they can interpret and understand their preferences and adjust advertising to those preferences.

That explains why, for example after seeing Youtube cars videos, we can notice seeing more ads related to the motor world while browsing other sites.

This is a potential threat to the privacy of users, hence the new laws governing the use of cookies.

European legislation and who must comply

We refer to the law of cookies, but this law does not actually exist as such, but as a part of the LSSI, The Spanigh Law of Services of the Information Society, which was amended by Spanish Royal Decree-Law 13/2012 of 30 March to adapt our legislation to the EU directives on electronic communications in Europe. Specifically, the aspects to which we refer in this article are the second paragraph of Article 22 of the LSSI.

The cookies legislation applies to any person or company acting as a seller or provider of any service in the digital environment.

To comply with the law of cookies it is necessary to inform and request users’ consent before installing cookies on their browser.

On September 13 2013, the reference to the Parliament of the Draft General Telecommunications Law, which includes a new amendment to Law 34/2002, of 11 July, of Services of the Information Society and Electronic Commerce was adopted, with which the cookie installation approval would pass consent from express to informed.

Exempt Cookies: What kind of cookies can be installed without permission

Exempt cookies are:

All those which have a technical character and are only intended to enable the navigation, or that are strictly necessary for the provision of the service.

Examples of exempt cookies

  • User input cookies
  • Session & authentication cookies
  • User security cookies
  • UI customization cookies
  • Social content plugin
  • Shopping cookies
  • Form cookies

Not exempted cookies

Not exempt cookies which are the ones that oblige the website to inform and obtain the user’s consent of both first and third-party cookies are the ones that address any other objective other than the exempt ones, for example, those used for analysis purpose, measurement or for third party advertisements on your own website app, or your products or services on other sites.
