We measure visits and game activity with PostHog EU. When you open Flight, PostHog stores a first-party cookie on jetten.app for up to 365 days. The cookie contains a random browser identifier so Flight can recognize the same browser on later visits. There is no analytics banner.
Analytics excludes names, drawings, voice audio, private room codes and invitation links. We do not use session replay, automatic click capture or person profiles. Do Not Track and Global Privacy Control disable analytics and prevent the analytics cookie from being created. Analytics requests go through our server to PostHog EU. PostHog privacy notice.
