Visitor data is not purged by default. For information about purging specific visitor data, contact your account representative.
Model training is not a one-time task. For that reason, visitor data is not purged. There will always be a need for new versions of visitor data to be trained and the data must therefore be available to retain. After a successful model is deployed, the model degrades over time and needs to be refreshed with current visitor data.
