Social networking site Facebook released the updated version of its privacy policy and asked its users to provide feedback.

Elliot Schrage, chief of communications at Facebook, wrote in a company's blog that users could send their comments by November 5.

Canada had been pressurizing Facebook to make changes in its privacy policy. Earlier, privacy czar Canada had conducted an inquiry into handling of personal information by Facebook.

Speaking on the topic, Elliot Schrage added, "In this revision we're fulfilling our commitment to the privacy commissioner of Canada to update our privacy policy to better describe a number of practices."

Facebook said it does not make use of conversion tracking that allows advertisers to assess the efficacy of their ads.

Facebook said that personal data is not provided to the advertisers.
