First-party cookies used by Matomo Analytics

We use Matomo web analytics to monitor and evaluate the effectiveness and efficiency of EROSS-SC website.

Matomo is an open-source analytics platform which fully is controlled by DG JUST. This platform enables the protection of end-user personal data thanks to features such as IP address de-identification. On top of that, the DG JUST has created a feature to manage users’ consent to the collection of users’ browsing experience for anonymised statistics.

Data protection information and measures in Matomo

Matomo is configured to store first-party cookies.

Cookies (from Matomo) enable EROSS-SC to track the following information about visitors. We use this information to prepare aggregated, anonymous statistics reports of visitors’ activity:

  • IP address (with 2 bytes masked)
  • Location: country, region, city, approximate latitude and longitude (Geolocation)
  • Date and time of the request (visit to the site)
  • Title of the page being viewed (Page Title)
  • URL of the page being viewed (Page URL)
  • URL of the page that was viewed prior to the current page (Referrer URL)
  • Screen resolution of user's device
  • Time in local visitor's time-zone
  • Files that were clicked and downloaded (Download)
  • Links to an outside domain that were clicked (Outlink)
  • Pages generation time (the time it takes for webpages to be generated by the webserver and then downloaded by the visitor: Page speed)
  • Main language of the browser being used (Accept-Language header)
  • Browser version, browser plugins (PDF, Flash, Java, …) operating system version, device identifier (User-Agent header)
  • Language of the visited page
  • Campaigns
  • Site Search

EROSS-SC retains full control of the data collected through first-party cookies by storing the data in servers fully owned and controlled by the Agency itself.

Besides some session cookies, a random ID persistent cookie is generated by Matomo, which allows EROSS-SC to identify when a user returns to the site. This cookie has an expiration date of 13 months, after which it is automatically removed from the user's device.

Do not track preferences

Do Not Track is a function that allows visitors not to be tracked by websites. Do NotTrack options are available in a number of browsers including:

Firefox (link is external)

Internet Explorer (link is external)

Chrome (link is external)

Safari (link is external)

Opera (link is external)

Restricted access to information

All analytics data communication is encrypted via HTTPS protocol. The analytical reports generated by Piwik can only be accessed by authorised Agency staff dealing with Matomo or by duly authorised external sub-contractors, who may be required to analyse, develop and/or regularly maintain certain sites.

Masking of IP addresses

Note: institution, city and country of origin for statistical purposes are determined from the full IP, then stored and aggregated before a mask is applied. Matomo uses an IP de-identification mechanism that automatically masks a portion of each visitor's IP (Internet Protocol), effectively making it impossible to identify a particular EROSS-SC website visitor via the sole IP address.

Visitor logs

Matomo automatically deletes visitors' logs after 54 weeks. Anonymised and aggregated data are stored for an indefinite period by EROSS-SC for analysis purposes.
