The location data gathered depends on several factors, including the technology used to deliver specific location-related functionality. The smartphone stores a small subset of the locations of cell towers and Wi-Fi hotspots it has most recently identified. When an application on the smartphone requests location information, nearby cell towers and Wi-Fi hotspots are detected. The smartphone then uses locally stored information for those that it recognizes. If sufficient information for positioning is not available on the device, it asks for its position from a positioning server, which maintains a database of known locations of cell towers and Wi-Fi hotspots, kept up to date in part with information on such locations, which is only sent by the smartphone to the server when these positioning methods are used. All communication to the positioning server is encrypted.
When customers choose to use Drive navigation in Maps, certain location data is sent to Nokia to report traffic jams, traffic patterns, changed road conditions and other such general information so that Nokia can provide a better service to all consumers, for example to provide alternative directions around a blocked road. This information, which is not personally identifiable, includes latitude/longitude, speed, direction and timestamp.
Positioning data, as described above, is not used to track consumers’ location but is used to provide the best service experience. The storage of certain positioning related data on the smartphone and its subsequent sharing with the positioning servers is essential for effective positioning. Without it, the performance of all positioning methods would be seriously impaired or they would not work at all.Nokia location based services and features may require the use of location data, for example to perform location based searches, provide local weather features or the street address of the current location when using Maps.Many Nokia smartphones also allow consumers to geo-tag content such as pictures and video with location data.
