You can ask for your data to be transferred to a third party

You are entitled to ask KBC Brussels for personal data that you yourself have provided to KBC Brussels with your consent or in the process of performing a contract to be transferred back to you or to a third party.

Legislation lays down a number of limitations to this right, as a result of which it does not apply to all data.
