“The online radio service Pandora has received a subpoena from a federal grand jury investigating whether popular smartphone applications share information about their users with advertisers and other third parties.

Pandora said it shared information with third parties to help it track how users interact with the service and to deliver targeted advertising. But the company, based in Oakland, Calif., said it was “not a specific target” of the grand jury investigation.

The disclosure comes at a time of mounting concern about Internet privacy and growing unease about the vast amounts of personal information that companies are scooping up online — from Web browsing habits to smartphone locations to Facebook preferences — and then mining to direct advertising.”
