User Persisted Storage is a feature we provide within growth and enterprise plans.
As you may already know, UserGuiding generates random unique user ids and stores them in your bowser's local storage. In addition, users' UserGuiding histories and thier properties are also kept in the local storage.
Therefore, when a browser's local storage is cleared, user ids and histories are wiped out as well.
User Persisted Storage is a solution we offer to keep the data persisted in the cloud.
When this feature is enabled, user ids, guides played, guides completed, step analytics and segmentation &custom attributes are kept in the cloud and accordingly retrieved each time an end user visits your website.
