Nokia collects non-personal and statistical information about the features uses on Maps and sends this out once a month. This is intended solely to help improve the service, and DOES NOT contain any personal information about you or your location. All information is anonymous, and is used for analysis on an aggregate basis.
In case you do not want to share information to help us improve Maps, you can click Settings > Participation and turn this OFF.
Once Participation is OFF, Nokia will not record any statistical information on your phone or send this to Nokia.
On data, Maps sends approximately 3 KB of data, once a week.
