Retention periods of data

Different types of data are stored for varying durations in Umbraco Engage. Use this article to learn about the specific storage periods and recommendations.

There is no reason to store your visitor data forever. As privacy is an important aspect of Umbraco Engage, you have tools to ensure you do not store the data forever.

You can configure Umbraco Engage to delete three data types after a certain period.

• Raw data is collected in the first phase of the data flow. This data is stored and parsed a few moments later. By default, this data gets deleted after 5 days. It is recommended that this data is stored for no longer than 30 days.

• Control group data is used for personalization purposes. When a visitor visits a personalized page, Umbraco Engage keeps track of whether that visitor is in a control group for user experience consistency. By default, this gets deleted after 180 days. The recommendation is to not increase this.

• Processed data is used for reporting and personalization purposes. You most likely need this for a long time. By default, Umbraco Engage anonymizes this data after 2 years and deletes it after 3 years.

  • The first privacy step is to anonymize the data so it cannot be linked back to an individual visitor anymore.

  • Besides anonymization, it makes sense to clean up that anonymized data somewhere in the future. What good is this information after 8 years for example? You should ask yourself this question and set the correct setting in the configuration file.
