Apple has issued a Q&A on location data. Looks like Alex Levinson was largely right, and that Marco Arment (who I concurred with), who said the data retention was a bug, was also right.

The major take-homes, if you don’t want to read through Apple’s piece:

  • Apple’s not tracking you, you paranoid crazy person.
  • Apple’s in fact ‘crowdsourcing’ a database of Wi-Fi hotspots and cell towers, to make your iOS devices more rapidly and accurately calculate their locations when they need to.
  • The data doesn’t include your actual location itself, but may include locations up to 100 miles from your device. (This may be a minor problem if your property is, say, a small country, but otherwise you can stop panicking now.)
  • A software update due in a few weeks will reduce the cache from a year’s worth of data to a week’s worth, delete the cache entirely if you turn off location services, and cease to back-up the cache.

Compared to the Sony PSN disaster (where even credit card details “may” have been stolen), the Apple story’s looking rather damp-squibbish now. What will be interesting is to see how Apple’s rivals in the smartphone space respond, seeing as some of them also track and retain location and other data.
