Cell phones are now constantly hooked up to the internet via mobile signal and owners can be tracked to within inches of their actual location.

For owners of an Android device or anyone who's signed up to Google Now, this detailed data is instantly beamed to their Google account, where it can be stored for months.

These movements can now be viewed on a fully interactive location history map, 'Express.co.uk' reported.

Once logged into a Google account, users simply click on a day, week or month and the map lights up with red dots and lines showing exactly where they have been.

However, Google said that the service they provide is not compulsory and users can turn location services off.
