If you're like millions of other people, you probably use Google Maps for navigation frequently. When you do, your navigation data is shared with Google to improve the product.

And while this is nothing new, users on iOS and Android today are seeing a prompt regarding Google Maps data sharing. A recent Google Maps update is disabling turn-by-turn voice directions and navigation instructions if you don't agree to share your data with Google.

This new pop-up prompt explains what's happening in greater detail.

"As you navigate, Google collects details, such as GPS location and the route you took. This data may be used to make information, including real-time traffic conditions and disruptions, visible to others and help them find the fastest route."

If you don't agree to share that data and instead hit "Cancel," Google Maps disables turn-by-turn navigation completely. Instead, users will see the older list-view of instructions, and that's all. You won't get voice instructions or turn-by-turn navigation. You can read more about navigation data here.

Again, Maps has always used this location data, and you likely agreed to it the first time you opened Google Maps or used navigation. This change reconfirms this information to users, likely in an attempt to be more open and transparent about data collection policies and user privacy. Something the company talked about during its annual Google IO developer conference earlier this year.

So far, it doesn't look like anything has changed in terms of collection practices or features, and instead, Google's just making things clearer and allowing users to opt-out.
