+## Keep Trageting Data On Unsubscribe
+
+(Available from version 1.23.5)
+
+By default, the SDK automatically removes the following data from local storage when a user unsubscribes: Subscription ID, Topics, Tags, Attributes
+
+The default value of `keepTargetingDataOnUnsubscribe` is false.
+
+Set `keepTargetingDataOnUnsubscribe` to `true` to retain user targeting data locally even after the user unsubscribes.
+
+This ensures that Topics, Tags, and Attributes are preserved locally, even when the user is no longer subscribed.
+
+The subscriptionId is always removed and is not controlled by this flag. 
+
+On every `Unsubscribe()` call, the SDK removes: Subscription ID, Related sync/created fields
+
+When `keepTargetingDataOnUnsubscribe` is enabled (true), the SDK keeps only: Topics, Topic version, Tags, Attributes
