The Belgian Competition Authority (BCA) attaches great importance to the careful handling of your personal data. The first step is to give you clear information about this. Below you can read the answers to some frequently asked questions.

  • What is personal data?

The General Data Protection Regulation (GDPR) defines "personal data" as any information relating to an identified or identifiable natural person. This information directly concerns a person or can be attributed to that person.
Personal data is therefore information that is traceable to you as a person, such as your first name, last name, home address, e-mail address and IP address. Telephone numbers and postal codes with house numbers are also personal data. Data showing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership or state of health receive special protection in the legislation.

  • Why do we collect and process personal data?

The collection and processing of personal data is used to perform the legal tasks assigned to the BCA. For example, this information helps the Authority to identify the person responsible for infringement of the free competition rules , to start an investigation into competition problems who have been signaled to us by consumers and businesses and to impose sanctions on the offender, if necessary.
We also collect and process data for statistical and qualitative purposes to improve the functioning of the BCA.

  • How long do we keep your data?

Your personal data will not be stored longer than necessary for the specified purpose of the data processing. If, for example, an investigation is completed and the data are no longer needed, the date will be erased.

  • Will your data be shared by us with third parties?

When performing our legal tasks, we may share data, including personal data, with third parties, for example with other supervisory or judicial authorities, but only if this is expressly permitted by law.

  • Are your personal data safe?

The BCA guarantees the security (integrity and confidentiality) of your personal data. They are protected against unauthorized access and use. Anyone working at the Authority is bound by professional secrecy.

  • How do we collect personal data?

The performance of BCA’s legal tasks requires the processing of personal data. Some examples :
- If we do research into a company and collect documents or e-mails relating thereto, these often contain personal data;
- When you contact us, for example to report a cartel by mail, email or otherwise, or to obtain leniency, we process your data;
- when you surf on our web page;
- we also collect information, including personal data, via public sources such as the Internet.

  • Why do we store your personal data after you contacted us?

If you repeatedly contact us, the Authority can see what has been discussed in a previous contact with you. Your information is also important for the performance of our legal tasks. In order to determine whether a company is complying with the rules, further investigation is often required and this may take some time.
