Personal data

TRACKEUR requests your explicit consent to collect the following personal data: 

  • Location data
  • Information you volunteer in the surveys

If you do not provide your consent, you are unable to participate in research projects conducted with the TRACKEUR tool. In our surveys we ask you questions on gender and age. In these cases we will always provide the option: ‘decline answer’. If you select this option, you can still participate in the research project. 


TRACKEUR is a research tool and can be used for various research projects. The specific objective(s) of a particular research project can always be viewed in the section ‘about this research project’ in the TRACKEUR appThe objectives fall within the purview of fundamental or applied scientific research and is conducted in close cooperation with governments and private companies. 

Sharing personal data with third-parties

The personal data of individuals collected by TRACKEUR will not be shared with third-parties. Results are always anonymized prior to publication.

Erasmus UPT will never sell your data to third-parties and will only share your data to fulfill our agreement with you or to meet a legal requirement.

We take appropriate security precautions to ensure that the risk of unauthorized access to and misuse of your data is reduced. We ensure that only authorized people have access to the data, that access is restricted and that our security precautions are regularly updated.

Your personal data identified by a pseudonym is stored for ten year after publication of the final research publication. The retention period may be changed to conform to the VSNU-code of conduct. Your data may be used by other researchers appointed by Erasmus University Rotterdam to reproduce the research results as part of an inquiry into scientific integrity. Researchers appointed to an evaluation committee on research ethics and integrity will be held to the same requirements as set out in this privacy statement. 

Rights of participants
