Unless your data has to be retained to comply with a legal obligation, it will be destroyed or made anonymous 10 years after the end of your membership. 

    8. What are your rights?

    Any person whose personal data is processed by ACV-CSC may exercise certain rights. Please note that some of these rights are not absolute. This means that they can be exercised, provided that they do not conflict with the legal obligations to which ACV-CSC is subject or with a task of general interest entrusted to ACV-CSC.
