Apple has issued a Q&A on the location data controversy in iOS. Basically the location data iOS cached are mainly geo-tagged Wi-Fi hotspot and cell tower data, in order to provide faster Location Service API to apps. There is no intention on Apple’s part to track your location. Future software update will reduce the size of this cache data, encrypted it for security and delete it when you turn off Location Services.
Sometime in the next few weeks Apple will release a free iOS software update that:
- reduces the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone,
- ceases backing up this cache, and
- deletes this cache entirely when Location Services is turned off.
In the next major iOS software release the cache will also be encrypted on the iPhone.
