This is the licence for the Intelliphone app.

Once you install this app, you can legally use Intelliphone on all the devices on your account.

After installing, just start this app once. You will see a message acknowledging your licence, then this app will no longer be shown to you. 
But it needs to remain installed on your phone for the licence to be valid. If you remove it by mistake, you can download it again without paying.
