Site analytics privacy
JustinFreres uses first-party reports to understand public website visits and improve the main website, games and course examples. Reports include a public page path, referring hostname, broad device category, visible time and selected link clicks. Query strings and URL fragments are never reported. We do not collect email addresses, IP addresses, precise location or device fingerprints in these analytics records.
A random tab identifier is kept in session storage for approximately 30 minutes between page loads. It is not a tracking cookie, is not joined across websites and does not identify a person. Visits are approximate. Reports are retained for 90 days in the existing private database. Private administration, account, grades, order and verification routes are excluded. The reader page is reported only as /reader.html; private links and email details are excluded.
Browser Do Not Track and Global Privacy Control preferences disable this collection. You can also opt out on each website using the button below. This preference affects analytics only. Game-operation reporting, account security, orders, transactional email and existing advertising choices have their own purposes and notices.
