A modern smartphone uses navigational satellites—sometimes drawing from multiple orbital systems—as well as cellular towers, Bluetooth hints, and Wi-Fi router locations to produce an awfully precise location. My family’s iPhones are often tracked not just at our house but—when looking in the Find My app—to each of our nearly exactly locations in our home within a few feet.
That might be too much when you’re giving a third-party app your location even once, but especially whenever the app is in the foreground, or, for rare apps, continuously in the background. In iOS 14 and iPadOS 14, Apple added a switch to let you choose to offer either precision or “fuzzed” locations to apps—and by extension to any third parties that the apps might work with, who receive location information as well.
When an app first asks for permission to track your location, a Precise: On label now overlays the map that appears in the dialog. The map shows the pinpoint location that would be sent at that moment. Tap the precision lozenge, and Precise: On switches to Precise: Off, and the map now appears with a circle that indicates the estimated area your phone would send instead.
You receive this permission notification again if you tap Allow Once the next time you run the app and it asks again; with any other choice, you won’t be prompted this way again. However, you can toggle precision at any time for any app via Settings > Privacy > Location Services. Tap the app’s listed and you can switch Precise Location on or off.
