- Name of the requested file and transferred data volume
- Notification of successful retrieval
- Browser type and version, operating system

4Cookies, local storage and consent
A consent banner appears on your first visit to this website. The optional categories “Statistics” and “Marketing” are disabled by default, and declining is offered with the same prominence as accepting. Before you decide, and after a refusal, no optional cookies are set and no third-party services are loaded.

Your consent decision itself is stored as a technically necessary entry in local storage.
You can withdraw or adjust your consent at any time with effect for the future: via the or the “Cookie settings” link in the footer of every page. When you withdraw statistics consent, existing Google Analytics cookies are deleted.
