When you access this website, certain technical information is transmitted by your browser and processed by the hosting provider in server log files. This includes: IP address, date and time of the request, page requested, HTTP status code, amount of data transferred, referring URL (if any), and browser / operating system identifiers.

4. Tracking links

The controller occasionally distributes individualised tracking links of the form www.olivierocannelli.com/r/<identifier>, intended for specific recipients (e.g. addressees of professional outreach). When such a link is clicked, the following information is recorded before the visitor is redirected to the homepage:

Purpose: Measuring the effectiveness of personalised professional outreach (e.g., job applications, collaboration proposals).
Legal basis: Art. 6(1)(f) GDPR — legitimate interest in evaluating own outreach activities, weighed against the limited and pseudonymised nature of the data collected.
Retention: Click records are retained for no longer than 90 days, after which they are deleted.
No third-party transfer: Geolocation is derived from the hosting provider's edge network; no separate geolocation service is contacted.
