# Close SDK Client

In most applications, you won't need to close the SDK client.

However, you should close the SDK client if:

* Your application is about to terminate. Closing the client ensures that all associated resources are released.
* You have determined that you do not need to evaluate flags again in your application lifecycle.

{% hint style="info" %}
**IMPORTANT**

The SDK does not evaluate flags after the client is closed.
