Consumers who have signed up for Google's consumer services, such as Gmail, Picasa, YouTube and Blogger, will now be able to access information that is stored about them.
With the launch of Google Dashboard, users will be able to check personal details that the search engine company holds, as well as edit and delete as necessary.
The move was made to ease the fears of privacy campaigners, whose concerns about the way Google safeguards personal data have become increasingly apparent.
A statement on the Google Blog says that the dashboard has been introduced "to provide [people] with greater transparency and control over their own data".
"The scale and level of detail of the Dashboard is unprecedented and we're delighted to be the first internet company to offer this - and we hope it will become the standard," the blog adds.
Responding to the new service, Consumer Watchdog said that consumers will not have adequate control over protecting all their personal details.
Although welcoming the Dashboard tool, the organisation suggested that giving users the option of being anonymous from Google and its advertisers in areas such as online behaviour and search data would have provided consumers with more control.
