Cookies are small text files that websites store on your computer or mobile device. They collect information about - for example - your personal preferences, website visits and device in order to improve the functionality and user experience of those websites.


What are cookies and why are they important?

Cookies are small text files that websites store on your computer or mobile device. They collect information about - for example - your personal preferences, website visits and device in order to improve the functionality and user experience of those websites. Some cookies collect personal data directly or indirectly and are therefore privacy-sensitive. Therefore, they are also subject to European and Belgian legislation. The use of cookies is regulated by the European Parliament and the Council of the European Union through e-Privacy Directive 2002/58/EC.

All EU member states have now transposed that directive into national law. This implies that cookie use and cookie legislation is regulated differently in each European country.   

In Belgium, this is done through a modified version of Article 129 of the Act of 13 June 2005 on electronic communication.

Use of cookies

During your visit to the Website, cookies may be used, which are small pieces of information placed on the hard disk of your computer. When you next visit this site, they make it easier for you to browse because, for example, you do not have to log in again or re-enter your preferences or password. The information collected by these cookies can be used to create a profile that ensures that the information offered is better tailored to your needs and preferences. For example, the website may


What cookies does BASL use, for what purposes?

Types of cookies 
Different types of cookies may be used on the Website:   

Essential cookies 
Essential cookies are cookies that are necessary for the Website to function (better). Without these cookies, some parts of the Website will not work or will not work optimally. These cookies do not collect data that can be used for marketing purposes or to remember your browsing history.  

Functional cookies 
Functional cookies collect information about visitors' choices and preferences and provide the ability to remember and personalise language and other local settings. The information these cookies collect is stored anonymously.

Tracking cookies
These cookies will outlive user sessions. When the maximum age of a persistent cookie is set to 1 year, within that year the initial value recorded in that cookie will be sent back to the server every time the user visits the server. This is done to store essential information (such as how the user initially came to the website). This is why they are also called tracking cookies. For example, when you have chosen your preferred language, the Website will record your preference in a permanent cookie and store it on your browser. When you subsequently revisit the Website, the Website will use that persistent cookie to ensure that content is delivered in your preferred language.

Performance cookies
These cookies help to improve the performance of the Website to ensure a better user experience. BASL uses Google Analytics for this purpose. Google Analytics uses cookies to help us analyse how users use the Website. It records the number of visitors and gives us information about overall visitor behaviour - such as the typical length of a visit to the Website or the number of pages a user views on average.

Targeting or advertising cookies
Targeting or advertising cookies track (the browsing behaviour of) visitors to build customer or user profiles. These profiles are usually used to show relevant and personalised advertisements that match the interests of matching users. In addition, they are used to measure the effectiveness of advertising campaigns and to perform market analysis.

Third party cookies
To support its forms of communication, BASL has embedded its content in social media channels, such as YouTube, Facebook, Twitter and LinkedIn. BASL also uses sharing options on social networks. The channels used by BASL may contain cookies from these websites. Would you like more information about these cookies? Then you should consult the relevant website of these 'third parties'.

Social media and their plug-ins 
Many social media (such as Facebook, Linkedin, Twitter, Google+, Tumblr, etc.) receive information about your surfing behaviour via social plug-ins on their websites (e.g. via the "Like" or "Share" buttons). These buttons may also be located on the Website. If you want to protect yourself against this, it is recommended (by Centrum voor de Bescherming van de Persoonlijke Levenssfeer, among others) to take one of the measures below.

Install a browser add-on that blocks tracking. Examples of such browser add-ons are:


  • Make use of your browser's incognito or "private nagivation" mode. Recent versions of the most common browsers offer such a private mode as functionality:

This feature forces the browser to erase traces of your browsing behaviour (cookies, history, etc.) after the window is closed, thus protecting you from being tracked by third parties (note: this feature does not make you anonymous on the web). There are also special privacy-protecting browsers, such as Epic Privacy Browser ( Social media and other websites use information about its users' browsing behaviour to offer them targeted advertising. If you no longer want to be tracked for targeted advertising, you can opt out of targeted ads via the European Interactive Digital Advertising Alliance's opt-out website ( 

Unsubscribing from targeted ads does not mean that information about your browsing behaviour will no longer be collected. If you also want to protect yourself from the collection of this information, you are advised to additionally use the incognito mode of your browser or use one of the above-mentioned browser add-ons.

We recommend that you regularly consult the following privacy and cookie statements

How we process data

We will process your personal data in a lawful, fair and transparent manner. Furthermore, we will make every effort to keep personal data accurate and up-to-date. Your personal data will only be processed for as long as necessary to fulfil the purposes set out in this Privacy Policy or until such time as you withdraw your consent to its processing. Please note that withdrawal of consent may imply that you are no longer able to use all or part of the Website and/or Services. If you have registered with the Website, we will delete your personal data when you delete your profile, unless a legal or regulatory obligation or a court or administrative order would prevent us from doing so.

We will take appropriate technical and organisational measures to keep your personal data secure against unauthorised access or theft and against accidental loss, manipulation or destruction. Access by our staff or staff of our third-party processors is only possible on a need-to-know basis and is subject to strict confidentiality obligations. However, you understand that care for safety and security are only best-efforts obligations that can never be guaranteed.


Your rights

You have the right to request access to any personal data we process about you. However, requests for access made with the apparent intention of causing inconvenience or damage to us will not be processed.

You have the right to request that any personal data about you that is incorrect or inaccurate be corrected free of charge. If you have registered on our Website, you can correct many of these details yourself via your profile. If such a request is made, you must also enclose with this request proof that the personal data for which correction is requested is incorrect.

You have the right to withdraw your previously given consent to the processing of your personal data. You may withdraw your consent at any time by sending an e-mail to, or by deleting your profile (if applicable).

You have the right to request that personal data relating to you be deleted if it is no longer necessary in light of the purposes set out in this Privacy Policy or if you withdraw your consent to its processing.

In lieu of deletion, you may also request.

You have the right to oppose the processing of personal data if you can prove that there are serious and legitimate reasons related to special circumstances that justify such an opposition. However, if the intended processing is classified as direct marketing, you have the right to oppose such processing free of charge and without justification.

The technical feasibility of this will be assessed solely by us.

It should also be dated, signed and accompanied by a digitally scanned copy of your valid ID card proving your identity. We will immediately inform you of the receipt of such request.
