The installation of the app is a standard procedure and is the same as for any other app for Jira cloud. You buy a cloud app by subscribing to it. First, you start a free trial, and then the subscription starts automatically after the trial period.

## Start with your Power Custom Fields™ for Jira Cloud

1. In your test cloud Jira instance, click the Jira icon, then go to **Jira settings →  Apps → Find new apps**.
2. In the search, enter "Power Custom Fields".
3. Click **Free trial** to download and install your app.

Note that although you can re-enable the trial within the original trial period, you can't *try* it again beyond the original trial period. At that point, you can only *subscribe* to the app from the Manage add-ons page. For more details, see [Atlassian documentation](https://confluence.atlassian.com/adminjiracloud/managing-add-ons-776830283.html#Managingadd-ons-Findandaddnewapps).


## End subscription of your Power Custom Fields™ for Jira Cloud

If you don't terminate the trial within the trial period, a subscription for the app kicks in. Trials last for a month from the start of your next billing date. After starting a trial, you can stop it from the app administration page. 

To end a subscription for Power Custom Fields for Jira Cloud, perform the following steps:

1. In your test cloud Jira instance, go to **Home → Settings → Apps →  Manage apps**.
2. Locate Power Custom Fields for Jira Cloud and expand its panel.
3. Click **Unsubscribe**.

Canceling an app subscription takes effect immediately.
