Luxembourg Privacy

he purpose of this note is to provide for comprehensive guidelines regarding retention periods for personal data processed in Luxembourg.

As a reminder, Luxembourg is a Member State of the European Union ("EU") and therefore falls under the scope of the General Data Protection Regulation (Regulation (EU) 2016/679 of 27 April 2016) ("GDPR").

As a European regulation, the GDPR is directly applicable in Luxembourg law and does not require to be transposed into national law. Therefore, except where permitted by the GDPR and necessary, Luxembourg has not adopted any other law to govern personal data collection, processing, and protection. The GDPR became applicable on the 25 May 2018.

Although the GDPR is the main source of legal obligations for processing of personal data in Luxembourg, other laws should also be mentioned as source of the obligations.

Two laws of 1st August 2018:

  • the Law on the organization of the National Data Protection Commission and the implementation of the GDPR (Loi du 1er août 2018 portant organisation de la Commission nationale pour la protection des données et du régime général sur la protection des données);
  • the Law on the protection of individuals regarding the processing of personal data in criminal matters and in matters of national security, which transposes into national criminal law the principles and obligations provided by the GDPR (Loi du 1er août 2018 relative à la protection des personnes physiques à l'égard du traitement des données à caractère personnel en matière pénale ainsi qu'en matière de sécurité nationale).

Law of 30 May 2005 on specific provisions for the protection of individuals with regard to the processing of personal data in the electronic communications sector (Loi du 30 May 2005 relative aux dispositions spécifiques de protection de la personne à l'égard du traitement des données à caractère personnel dans le secteur des communications électroniques).

Finally, for the specific purpose of data retention, there may be other applicable laws which will be indicated below when relevant.

Guidelines

Several steps shall be followed in order to comply with Luxembourg Law:

1) Adoption and implementation of a retention and deletion policy

In order to comply with the obligations set out in the GDPR, companies shall adopt and implement a retention and deletion policy (the "Policy").

Such Policy shall serve as one of the internal norms on the basis of which personal data collected by the company in the course of its business shall be processed.

The Policy shall be comprehensive, meaning that its scope shall cover all relevant data collected and processed by the company, on any material support (e.g., paper, electronically, or any other support); and shall include all types of records which the company creates or holds (e.g., employee information; information on clients and/or external parties; corporate files; contracts and invoices; tax files; registers; legal files; etc.)

The Policy shall also apply to all members of the company.

The Policy shall set forth a clear and precise retention schedule for all records, but which varies according to their nature and considering the support on which they are stored.

Finally, the Policy shall provide for a period of time after which it will have to be reviewed and amended where relevant.

2) Identifying the roles played in respect of the Policy \

The Policy shall clearly identify the persons responsible for its implementation.

Usually:

  • the executive board is in charge of drafting and adopting the Policy and also of reviewing the Policy after a reasonable period of time;
  • the management (g., directors, etc.) is responsible for ensuring that the Policy is correctly applied and enforced within the company. They are also in charge of deciding on extending the retention period of a specific record and on disposing of such record;
  • the Data Protection Officer, if appointed, is responsible for administering the Policy and dealing with the everyday queries and challenges.

3) Define a retention schedule

The Policy shall set out a comprehensive retention schedule which will list each type of data that will be collected and processed by the company in the course of its business.

The general principle is that the collected and processed data shall not be retained by the company for a period longer than what is necessary for achieving the purposes for which the data was collected and processed in the first place. The idea behind this principle is that the company shall find the right balance (proportionality) between its commercial needs – justifying that personal data is retained for a certain period of time – and the privacy rights of the people whose data has been collected and processed.

The company shall identify the proportionate retention period for each type of collected and processed data, depending on its nature and on the support on which it was recorded. The Policy shall provide for the minimum amount of time during which the data will be stored by the company, but also a general maximum period after which the data will be destroyed.

Generally personal data should not be kept longer than the applicable limitation period in accordance with applicable law.

Therefore, most retention policies in Luxembourg provide for an average minimum retention period of 10 years for most of the collected and processed data. This is due to the fact that general prescription for claims in commercial matters, i.e. involving companies is 10 years.

Nevertheless, the company has the right to individually and proportionally extend the retention period of a specific record, as long as it is justified by the legitimate interests of the company. The circumstances in which such decision may be taken shall be duly provided by the Policy, and the Policy shall also clearly identify the persons within the company responsible for taking such decision. In any case, the decision to extend a retention period shall be duly motivated and record in particular why the legitimate interests pursued by the company are not overridden by the interests or fundamental rights and freedoms of the data subject.

The maximum retention period is usually 30 years, as this is the longest limitation period applicable under Luxembourg Civil Code.

See Annexes for examples of applicable retention periods.

4) Define a deletion policy

The Policy shall also regulate the deletion of the retained data.

Once a retention period has expired, the company shall delete the recorded data if the retention period has not been extended.

Deletion can take the form of either:

  • destruction; or
  • anonymization

The Policy shall clearly provide for the circumstances in which a record shall be destroyed and in which it shall be anonymized.

Confidentiality of the data shall always be ensured during the process.

5) Communication of and information about the Policy

Finally, once the Policy has been adopted, the company shall ensure that all its employees and all the third parties who may have their data collected and processed by the company have been informed about the Policy and have access to such Policy.

The retention schedules provided below serve only as examples of a common practice in Luxembourg:
