Facebook signs apps privacy agreement

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.

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.

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.

The other six companies are Apple Inc., Google Inc., Amazon.com Inc., Microsoft Corp., Research in Motion Ltd. and Hewlett-Packard Co.
