Today Google "sees" everything. Most Google products like Google Desktop, Google Chrome, Google Picasa, Google Earth and Google Toolbar collect data about the usage, generate a unique ID and transfer them back to Google.
GoogleClean can prevent this and switches of those data transfers. It allows you to use all Google products without any headaches and without having to worry about the consequences. GoogleClean does not influence the functionality of Google products. It takes away the bad things and leaves you the good things.
