“We use telemetry from all Mapbox SDKs to improve our map, directions, travel times, and search. We collect anonymous data about how users interact with the map to help developers build better location based applications. Location telemetry is critical to improving the map. We use the data to discover missing roads, determine turn restrictions, build speed profiles, and improve OpenStreetMap.”
