Why Buro de Vakmannen needs personal data

Buro de Vakmannen processes your personal data to be able to contact you by telephone if you request it, and / or to be able to contact you in writing (by e-mail and / or by post) if you can not be reached by telephone. This is often the case in the framework of the (possibly future) execution of an agreement with you, usually consisting of legal services.


We also process personal data when you register for a meeting, workshop or other event that Buro de Vakmannen organizes. We never store that data for longer than is necessary and use it only for the purpose we have let you know in advance.


We also process personal data when performing user research. This can for example be a user test or interview at a location where we invite you (on site research), or an online survey or a (telephone) user survey. Sometimes we also make image and sound recordings from both online and on site surveys. We always ask for your permission beforehand and we do not store any data longer than necessary.


How long does Buro de Vakmannen retain the personal data

Buro de Vakmannen never stores your personal data for longer than is strictly necessary to achieve the goals for which your data is collected. Usually this is a few weeks to a few months, but never longer than a year if no agreement is made with you. The only exception to this is when you, as a respondent, have explicitly given permission for using a photo (or other personal data) in presentations or social media.
