Any smartphone today uses navigation satellites, often coming from multiple orbital systems, in addition to cell phone towers, Bluetooth tracks, and Wi-Fi router locations to produce a terrifyingly accurate location.
The iPhones of my family are often tracked not only in our house, but also, the application ‘Find’ is used, in each of the almost exact locations of our house within a radius of a few meters.
This can be too much when you give a third-party app your location even once, but especially when the app is in the foreground or, in the case of rare apps, continuously in the background.
In iOS 14 and iPadOS 14, Apple added a toggle so that you can choose between offering apps precise or “fuzzy” locations and, by extension, any third party the apps may work with, which also receives location information.
When an app asks for permission to track your location for the first time, pin it on the label that overlaps the map that appears in the dialog. The map shows the exact location that would be shipped at that time.
Tap the precision pickup, and if it’s on, turn it off and the map now appears with a circle indicating the estimated area your phone would send instead.
You will receive this permission notification again if you press ‘Allow’ once the next time you run the application and it asks you again; with any other option, you will not be asked this way again.
However, you can change the precision at any time for any application through ‘Settings> Privacy> Location services’. Tap on the app listed and you can turn ‘Pinpoint location’ on or off.
