This website uses Piwik, a Free Software web analytics system, to monitor traffic on our Web sites. Piwik records the general geographical vicinity of visitors as well as their browser and operating system, and records their navigation within the sites. This helps us gauge the impact of our materials and improve our work.

Our Piwik system preserves privacy by anonymizing visitors’ IP addresses. This means that we will not store any personally identifiable information about you, even though your visit produces a record that our site was visited by someone.

Piwik also respects the “Do Not Track” preference offered by some browsers, so if you have this option set, Piwik will ignore your visit entirely. Details of how Piwik protects privacy are on their website.
