In an updated version of its privacy policy, the company added a paragraph noting that once users agree, Apple and unspecified "partners and licensees" may collect and store user location data.

When users attempt to download apps or media from the iTunes store, they are prompted to agree to the new terms and conditions. Until they agree, they cannot download anything through the store.

The company says the data is anonymous and does not personally identify users. Analysts have shown, however, that large, specific data sets can be used to identify people based on behavior patterns.
