The membership duration in Firebase’s Predictive Audiences refers to the number of days that users will remain in that particular predictive audience. For example, if you set the duration for one month, then users predicted to churn would stay in that audience for a month. If you opt for the ‘max limit’, users will stay in the audience for the maximum duration allowed by Firebase, which is 540 days. However, each day Firebase updates its predictive metrics for active users. If a user initially predicted to churn does something that changes this prediction, they will still remain in the predictive audience until the end of the set membership duration. Despite the daily updates, the user will not be removed midway through the duration. It’s a way of not losing track of users due to sporadic changes in behavior or prediction models. So even if the prediction changes the next day, the user will continue being a part of the audience for that month (given a month-long membership duration) or until the end of the duration you set.
