Churned User
BeginnerA churned user is a user who has met the product's churn definition and is counted as lost in reports until they come back.
Churned is a state, not a permanent attribute. The label is assigned by a rule, and in a non-contractual product it is always provisional, because a user can return the day after the threshold expires and be reclassified as resurrected in the next report. In a lifecycle report the churned state sits alongside new, active, dormant and resurrected, and each user occupies exactly one of them per period. The common trap is taking the whole churned list as the audience for a win-back campaign: someone who never activated and someone who paid for two years sit in the same bucket, and only the second has a relationship worth recovering. Identity limits matter as well, since a person who clears cookies or switches device can be counted as churned while still using the product.
