When you use augmented reality on Apple Maps, you can hold upiphoneto scan your surroundings and detect feature points from nearby buildings and other physical features.

Apple points out that when you use augmented reality features, related photos are not sent to Apple or stored on the device, and the system only collects related data. Relevant feature points will be tested in a way that cannot be read by humans, and the iPhone camera will filter out moving objects such as people and vehicles. Apple Maps only requires feature point data of surrounding static objects.

In addition, the data collected by Apple will be encrypted and will not be associated with an individual user or Apple ID. Apple also adds "noise" to the data to add irregular variations that prevent the possibility of reconstructing an image from the data.

You can start or stop sharing your data at any time to help improve the accuracy of real-world targeting.

• Open the Settings app.

• Click Privacy & Security, then Analytics & Improvements.

• Turn "Improve AR positioning accuracy" on or off.

• You can choose to share data with Apple in your privacy and security settings to improve AR positioning accuracy.
