# 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.

    "value": 'test-lifetime-server-cookie',
    "exdays": 1000 * 24 * 60 * 60 * 1000,
});

window.jentis.helper.setLocalStorageItem("test-lifetime-localstorage", "test-lifetime-localstorage", 1000 * 24 * 60 * 60 * 1000);


const cookie = window.jentis.helper.readCookie('test-lifetime-cookie');

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jentis.com/jentis-dcp-elements/account-settings/maximum-storage-lifetime.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
