(CBS/AP) Facebook became the seventh company to agree to give people advance warning if its mobile applications pull personal information from mobile phones and tablet computers.
The other six companies are Apple, Google, Amazon, Microsoft, Research in Motion and Hewlett-Packard.
California Attorney General Kamala D. Harris said Friday that the agreement includes Facebook's own applications, as well as those made by third parties in its recently-launched App Center.
"[W]e hope that you will consider us a signatory to the Joint Statement," Erin M. Egan, Facebook's chief privacy officer, wrote in a letter to the California attorney general's office.
The agreement requires mobile apps seeking to collect personal information to display their privacy policies before their app is installed on a device.
Facebook says it incorporated the principles of the privacy agreement when it was designing its App Center.
"We are delighted that Facebook has joined Amazon, Apple, Google, Hewlett-Packard, Microsoft, and Research in Motion to provide consumers with greater control and information about how their personal data is used," Atty. Gen. Harris said in a press release. "We need to protect privacy while we foster innovation."
