Facebook has rejected suggestions its new smartphone software could destroy privacy by tracking a user's every move.

The social networking giant showcased its latest venture, Home, amid much fanfare

However, industry experts immediately raised fears over its potential to gather masses of personal data.

Mark Zuckerberg's site later dismissed the claims and stressed Home was not a new means of collecting information.

Om Malik, of technology website GigaOm, said Home would enable the social networking site to establish a user's address by using a phone's GPS even when an individual had opted not to share such details with Facebook.

"If you install this, then it is very likely that Facebook is going to be able to track your every move, and every little action," he said.
