A new study from the Future of Privacy Forum reveals that app developers, publishers and their legal teams are finally paying attention to the privacy laws being pushed by U.S. regulators and lawmakers. It would appear changes are stating to take effect. Here are the results of the study that collected data from September 2011 to June 2012 and looked at the 150 most popular apps across the Apple, Google, and Amazon platforms. Half of the apps were free and half were paid.

Apple -- the percentage of free apps that offer users some kind of privacy policy doubled, from 40 percent to 80 percent. The percentage of paid apps with privacy policies increased from 60 percent to 64 percent.

Google Play -- the percentage of free apps with a privacy policy increased from 70 percent to 76 percent. The percentage of paid apps with privacy policies increased from 30 percent to 48 percent.

Amazon’s Kindle Fire Appstore -- is the new kind on the block, having launched in March 2011 to sell Android apps for Amazon’s proprietary devices. The study found that 48 percent of their free apps and paid apps alike come with a privacy policy.

Across the board study found that 22.7 percent of free apps and 13.3 percent of paid apps provide access to a privacy policy on the app store listing page.

So it's not a privacy policy revolution but it's good to see efforts being made on this very important issue.
