Purpose of collected personal data;

This website is using Matomo, an Open Source, self-hosted software for collecting anonymous usage statistics for this website.

The data is used to analyse the behaviour of website visitors, to identify potential pitfalls like not found pages, search engine indexing issues and to find out which contents are the most visited.

Once the data (number of visitors reaching a not found page, viewing only one page, etc.) is processed, Matomo generates reports for website owners to take action, for example, changing the layout of the pages, publishing fresh content… etc.

Matomo and this website data is hosted in the United States.

When visitors leave comments on the site I collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.
