I'm using Matomo (ex-Piwik) to track visitor's data on my website. The purpose is to know
- how visitors come across my website
- how long they stay here
- whether they click on social / external resources
I do not need to know who you are exactly, and the data I collect are thus anonymized. Obviously, I do not allow any third party to access these data (unless laws require it, which is rarely the case under UE / Swiss legislation).
