What is a tag manager?
Do I need prior consent?
The general rule is that you can only store or readout cookies and scripts with a visitor’s prior consent. This doesn’t apply to all cookies and scripts, like ones which are purely functional or privacy-friendly. The Netherlands Authority for Consumers and Markets [ACM] recently has clarified that website owners may use tag managers without prior consent, even though there is no formal legal exception.
That is good news. Are there any conditions?
