Location of private Wi-Fi systems is used by Google to estimate a phone user’s location for some services. But many data protection authorities in Europe have objected to the practice. Google is to provide an option for wireless access point owners to opt-out from Google’s location services. From later this autumn owners worldwide will be able to opt out of the system and thereby not allow their access point details to be used. The exact time from when this will be available has not been announced; the method of opting-out has also not been described.”]
