Online radio service Pandora Media Inc said it has been subpoenaed by a Federal grand jury investigating the use of customer data by certain popular applications that run on mobile platforms of Apple Inc and Google Inc's Android.

Pandora said in a regulatory filing on Monday it believes it is not the specific target of the investigation and that similar subpoenas were issued on an industry-wide basis to the publishers of numerous other smartphone applications.

The company did not disclose the timing of its receipt of the subpoena.

The information was contained in a filing by Pandora ahead of a public offering of around $100 million expected later this year.
