Do reports contains personal data?

(Gui Gui Soft) #1

Does Matomo reports contains personal data (from the “GDPR” point of view) ?
I searched but didn’t find the answer in Matomo documentation.

It depends on if you have configured Matomo to track personal data and if you are manually tracking personal data (e.g. in custom dimensions or via UserID)

I collect userID and IP adresses but I assume they are not used in reports.
Are userID and IP adresses only stored in visitors logs ?

If yes, it seems good to me because I delete them after a certain amount of time, according to my data management policy.

Thank you for your help.

Keep in mind that only a lawyer can give you a correct answer, but if you are recording IP-Adresses and UserID, you are stroring personal data as they are both used to uniquely identify every website visitor.

I understand but my question here is technical, not legal

Are IP adresses and UserID stored in any other tables than:

  • log_conversion,
  • log_conversion_item,
  • log_link_visit_action,
  • log_visit,
  • log_action
