4. Sharing your Personal Data

Some of the above-mentioned recipients may be based outside of Luxembourg and the EU/EEE and process your personal data outside of Luxembourg.

In case of an intra-group transfer to another member firm located in a country that do not offer adequate protections, we use the European Commission's standard contractual clauses to provide adequate protection.

You may request additional information in relation to such cross-border transfers and obtain a copy of the safeguards put in place Grant Thornton Luxembourg by contacting our Data Protection Officer (DPO) at

An interfirm agreement between all Grant Thornton Luxembourg member firms that share and process personal data is in place. Where a third party service providers process personal data outside the EEA in the course of providing services to us, our written agreement with them will include appropriate measures, usually in the form of standard contractual clauses.


5. Data retention period

Your personal data is stored by Grant Thornton Luxembourg only for as long as is necessary for the purpose for which we obtained them. The retention period will depend upon several factors, such as the duration of the contract concluded with you, or legal requirements imposed to Grant Thornton Luxembourg.

Whenever we process your personal data on the basis of your consent, you have the right to withdraw your consent at any time by contacting us as indicated below or by clicking the unsubscribe link in the email communication we send you (e.g., Grant Thornton Luxembourg events, product updates, etc.). Please, note that the withdrawal of your consent does not affect the lawfulness of the personal data processing based on consent prior to its withdrawal.

In some circumstances we may anonymise your personal data so that it can no longer be associated with you, in which case it is no longer considered as personal data. Upon expiry of the applicable retention period, we will securely destroy your personal data in accordance with applicable laws and regulations.


6. Security

We implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk so that the processing complies with the GDPR.

These measures must provide for a level of security considered appropriate considering the technical standards and the type of personal data processed but also:

  • The state of the art and implementation costs;
  • The nature, scope, context, and purposes of processing; and
  • The likelihood and severity of the risk to the rights and freedoms of natural persons.

Security requirements are continually evolving, and effective security requires frequent assessment and regular improvement of outdated security measures. We are committed to continuously evaluate, strengthen, and improve the measures we implement.


 7. What are your rights regarding your data?

As a natural person, you have a number of rights regarding your personal data including:

  • The right of access: You can request access to the data concerning you at any time as well as a copy of the data;
  • The right to rectification: You can request at any time that inaccurate or incomplete data be rectified;
  • The right to request the erasure of data: You can request that your data be deleted when, for example, the data is no longer necessary for the purposes for which it was collected or processed;
  • The right to restriction of processing: You can request that Grant Thornton Luxembourg restrict the processing of data if, for example, you question the accuracy of the data concerning you or if you object to the processing of data concerning you;
  • The right to data portability: You have the right to have your data transferred to another data controller in a structured, commonly used and machine-readable format, if the processing is carried out by automated means or if it is based on prior consent;
  • The right to object to data processing: You can object to the processing of your data and can withdraw your consent if the processing is based on consent, for example if the data is used for commercial prospecting purposes.

These rights can be enforced within the limits defined by articles 15 to 23 of the RGPD.

For more information or if you wish to exercise your rights, please contact our Data Protection Officer (DPO) at

Requests will be dealt with by the DPO and will be responded to within 1 month at the latest, starting from the moment of your identity confirmation. We may extend the time limit by a further 2 months if the request is complex or if we have received a high number of requests.

We may request additional information to help us confirm your identity and to ensure that you respect your right to access the personal data (or to exercise any other of your rights). This is a security measure to ensure the non-disclosure of your personal data to an unauthorised person.

You will in general not have to pay a fee to exercise any of your individual rights mentioned in this Privacy Notice. However, we may charge a reasonable fee if your request to exercise your individual rights is manifestly unfounded or excessive. Alternatively, we may refuse to comply with the request in such circumstances.

If you are not satisfied with our response, you also have the right to lodge a complaint at any time with the National Commission for Data Protection (CNPD), the Luxembourg supervisory authority for data protection issues, or, as the case may be, any other competent supervisory authority of an EU member state.
