In the cloud: Your files are kept in Google's Drive cloud storage. They are free: As with Google's other consumer services - including Gmail and Calendar - the Google Docs productivity apps are free to use across any browser, including Google Chrome and Mozilla Firefox. The Google Docs collection of editors and services - which includes Docs, Sheets, Slides, Forms, Keep, Drawings, and Drive storage - is a free, easy-to-use, and unexpectedly rich collection of productivity tools.
