# Maximum Storage Lifetime

This feature allows users to configure the maximum lifetime for cookies and local storage entries set by JENTIS. Once a data entry's configured lifetime has expired, it will either be automatically removed by the browser (cookies) or removed by our script the next time a user accesses it (local storage).

**The Maximum lifetime can be configured on three levels:**

* Default set by JENTIS (730 days / 2 years)
* Global Default Customer setting, which is applicable for all containers of the JENTIS account
* Container level setting

We will always use the most specific setting when calculating the maximum lifetime. The lifetime limit is applied as soon as you publish your configuration.
