Google is preparing to launch a hosted storage service, according to notes that the company inadvertently published as part of a Powerpoint presentation for financial analysts last week.

"The notes were deleted from the slides we posted because they were not intended for publication," Google spokeswoman Lynn Fox said. She declined to further comment on the services that the company is currently developing.

The notes weren't visible for analysts at the event. They mentioned the desire for Google to house all user data such as files, emails, bookmarks and pictures on its servers rather then have the user save the information on their computers.

"We already have efforts in this direction in terms of GDrive, GDS, Lighthouse, but all of them face bandwidth and storage constraints today," the notes stated.

Offering to store this data allows users access to their data at any time and from any device, and also frees such information from Microsoft.

"This theme will help us make the client less important (thin client, thick server model) which suits our strength vis-a-vis Microsoft and is also of great value to the user."

The unintended publication of the notes forced Google to file the event with the Securities and Exchange Commission, which stated that certain of the annotated comments were not intended to be presented at the analyst day.

The SEC filing contained mostly predictions about Google's future financial performance because the search engine by law is required to make such information broadly available. It doesn’t need to disclose the plans for future product because they don't directly affect future earnings.
