## Edit the details of an Application

You can edit an [Application](/docs/product/applications/overview.md) to modify its name,
description, currency, and Application environment. You can also change
the [time zone setting](#timezone-impact),
but we do not recommend doing so.

Editing these details affects all the [campaigns](/docs/product/campaigns/overview.md)
contained in the Application that is edited.

### Change the time zone setting {#timezone-impact}

The primary time zone setting for Talon.One is the Application time zone,
which you select when you [create an Application](/docs/product/applications/create-and-manage-applications.md). However,
in some cases, other time zone settings apply.

}

To edit the details of an Application:

1. On the <Applications className="icon"/> **Apps** page,
   click <Settings className="icon"/> **Settings** for the Application you want to edit,
   or, from the Application's left-side menu,
   click <Settings className="icon"/> **Settings** > **Details**.
1. Edit the required details.
1. Click **Save Changes**.

## Delete an Application

When you delete an Application, all its information
(including campaigns, coupons, customer sessions and referrals) is erased,
and you cannot recover it. However, deleting an Application does not affect your
[customer profiles](/docs/product/applications/display-customer-profiles.md).

To delete an Application:

1. On the <Applications className="icon"/> **Apps** page,
   select the Application that you want to delete.
1. Click <Settings className="icon"/> **Settings** > **Delete**.
1. Click **Delete Application**.
1. In **Application Name**, type the name of the Application.
1. Click **I understand the consequences, delete this Application**.
