By default, if you set CCleaner Network to delete cookies, it will delete all cookies on an Endpoint. You can specify what cookies it will keep on this tab of the Settings dialog box.
To specify a domain from which CCleaner Network will not delete cookies, click Add Domain, type the domain name (for example, microsoft.com), and then click OK.
To remove a domain you have added to the list, select it and then click Remove. You are prompted to confirm the deletion.
