You can turn OFF advanced matching inside the plugin. This option is available on the plugin’s main page, in the Facebook ID area.
But you also need to turn OFF Automatic Advanced Matching inside your Facebook Events Manager, or make sure it’s OFF.
Keep in mind that this data is also sent with CAPI events, so you probably want to turn them OFF too.
As an alternative, you can inform your users and ask their permission for Advanced Matching and CAPI. This video can help: https://www.youtube.com/watch?v=PsKdCkKNeLU
Now I saw that when a person has not agreed with the cookies these values are not sent.
Do you think this is OK for GDPR?
