While technically bankruptcy courts may see customer data as an asset for sale, this action could be potentially blocked due to privacy concerns.

The phone numbers, e-mail addresses, and shopping habits of more than 100 million customers are part of RadioShack’s bankruptcy auction.  RadioShack’s customers—even those whose most recent purchase came years ago—could also find themselves sold off in the deal. The company included personal data in its bankruptcy auction as its own asset class. A website maintained by Hilco Streambank, which is serving as an intermediary for RadioShack, says that more than 13 million e-mail addresses and 65 million customer names and physical address files are for sale. Hilco Streambank is careful to note that the bankruptcy court might not approve the deals, and there have already been two legal filings in attempts to block the sale of customer data.

The broader challenge, filed last week by Texas Attorney General Ken Paxton, argues that RadioShack made an explicit promise to its customers not to sell their personal data. Paxton claims that 117 million people are included in RadioShack’s customer data sale, which he says offers some details about shopping habits. The filing cites text from a sign displayed in RadioShack stores reading: “We pride ourselves on not selling our private mailing list.” State law in Texas prohibits companies from selling personally identifiable information in a way that violates their own privacy policies. On Monday, Tennessee’s attorney general joined Texas’s objection.
