CCleaner VS Public School

Hi! I work for a public school and I like to know if it's possible to use CCleaner where I work? The web site isn't very clear on what is a business. My opinion anyway!

For businesses, from small companies to large enterprises, we offer Premium Business Support for all our products.

Usually ;-), business exist to make money. But public school exist only to render a service. In other words, we don't make any money out of it! So do we have to pay for CCleaner or can we use it legally in our school? We don't need anything fancy. Just need an application that clean temporary files at the user log off.

Thanks in advance for the help!

In simple, if your school allows you to install it. Then yes you are allowed to use it. CCleaner is freeware. There is no paid version.

Happy using

The premium support consists of an msi installer and more timely responses from devs if you need something fixed, if I understand it correctly.
