Hi @Chardonneaur. Thanks for the suggestion. In theory that would be possible. Afaik we are currently not storing the consent in the database, which would be required to make that possible.

There is a segment Profilable which let's you differentiate between people who were tracked without cookies (no consent) and people who gave consent for cookies or tracking. This would generally let you segment the people that did give consent. However, it requires the Visits Log to be enabled meaning if you don't pay attention you might also view the visits log with the regular All Visits segment. My understanding is that CNIL says you need to disable the visits log but haven't double checked.

A workaround would be to track visitors that gave consent additionally into a different site where the visits log is enabled.

A feature to make it work what you are after would be to have a "Profilable visits log" only.

Thank you Thomas, yes, exactly "Profilable visits log" only. Though the work around you gave with the "multiple tracker" can be a nice "ready to implement" option.
Do you know if the multiple tracker may be soon integrated within Matomo Tag Manager?

@Chardonneaur I don't think there are any plans. I guess the thought was that you can already add multiple tracker configurations now and it should work that way to track into two or more sites.

The problem may be though that if events are tracked, these need to be configured multiple times for each tracker which can be very annoying so we would maybe indeed need an "Add tracker" feature to configure multiple trackers in one Matomo Configuration Tag.

@tsteur thinking out loud here, but is the roll-up feature could be of any help here? Because, it can create a copy of an existing website + have its independent settings.

Rethinking about it, it won't be the perfect solution as we cannot disable individually plugins per site.
So for example if website 1 is collecting personal data such as the user ID, then the copy of this website (as a roll-up) will receive the user ID too (even if the log visit is disabled).
In fact one would need to be able to disable all PII data collection point per site.

@tsteur , in case of tracking to several sites, no need to create triggers multiple times, only the tags. Indeed, the tag config needs Matomo configuration (Matomo server target, site ID, etc.), whereas the trigger just needs an event (and eventually some additional restriction).
