Is it possible to change the Matomo settings so that Matomo does not collect personal at all? For example, only the following could be tracked:
How often a particular page was viewed (but not by whom)
Which campaigns received the most clicks (but not by whom)
Which campaigns received the most goals, etc.
As far as I understand it, such a Matomo version would be GDPR compliant without the need to show a cookie banner and without the need for consent (as no personal data is collected).

The idea of a even more anonymized version of Matomo that maybe even could be used to track users who have DNT enabled, is definitely worth discussion, even though every implementation needs to be planned carefully.
You can find a similar idea here:

we as a public german university have a problem with the behavior of Piwi
… k regarding DoNotTrack.
At the moment, if you configure Piwik to respect the DNT-header, visitors sending a DNT-header won't be counted at all (unless they come with IE, but that's another weird problem, see #9987). In my interpretation of the DNT-specification, a submitted DNT-header means, that a user doesn't want to be tracked, i.e. he/she doesn't want to get a cookie set (or any other method like fingerprinting) to be recognized as the same user on following visits. Or even within his particular visit, when it's interpreted strictly. This says nothing about counting his/her pageviews anonymized. It is called DoNotTrack, not DoNotCount.
So Piwik should count those visitors, but not track them, if the respect-DNT-setting is activated.
On my personal blog, I did some tests in 2014 and at this time, activating DNT in Piwik resulted in only about half counted visitors (from 100-150 visitors per day to 50-100 with DNT-feature activated). On other sites, I administrate, the impact was lower, but around 20% loss in counted visitors was standard then.
For our data protection commissioner it seems to be okay, if we then don't respect DNT at all, so we'll likely deactivate this feature. But this is a shame, since we want to respect the decision of our visitors, that they don't want to be tracked between their visits. But we also want reliable statistics.
I appreciate your comments on this.
