When you start turn-by-turn navigation, you’ll find a message that explains how navigation data makes Google
Maps more useful for everyone.
Navigation data has always helped—and continues to help—Google Maps provide real-time features, such as traffic conditions, disruptions, and the ability to find the fastest route.
How navigation data works
When you use Google Maps turn-by-turn navigation, Google collects data to help reflect the world in real-time for everyone. Data, such as:
- GPS location
- Transportation mode
- Navigation details, such as the route you took
- Sensor data from your devices, such as the barometer
Google uses your data by itself or combined with others to make Maps better, such as:
- Improving navigation
- Suggesting faster alternate routes to save time
- Showing real-time updates, such as traffic, disruptions, and weather conditions
How Google protects navigation data
- Navigation data, such as the route you took, isn’t associated with your Google Account. Instead, it’s associated with a securely generated identifier that resets on a regular basis. That means Maps can’t look up your navigation data based on your Google Account.
- Other data collected as you explore the world, such as the directions you searched for in Google Search before starting navigation, may be associated with your Google Account. You can change controls and manage activity, such as Location History or Web & App Activity, by visiting Your data in Maps.
- We only collect the navigation data we need to provide the best Maps experience for everyone—after processing, it’s deleted.
- We don't associate updates to the map with your Google Account or device.
