Google earlier announced that it is taking steps to further improve privacy practices. The company said in its blog:
Just as we continuously work to improve our products, we also work toward having the best privacy practices for our users. This includes designing privacy protections into our products (like Google Talk's "off the record" feature or's "pause" and "lock search" controls). This also means providing clear, easy to understand privacy policies that help you make informed decisions about using our services.
