I don't even know what that is...
Sorry.
End User Licence Agreement. The loooooooooooong text that 99.99% of the users skip and don't read. In the first releases of Chrome they wrote that by installing the software you authorize Google to use every piece of data transmitted via the browser, without necessary permission, credit, and for anything they want to.
Since I don't want one of the biggest companies on the planet to tamper with my private chats, photos, videos or personal data, I haven't installed Chrome so far.
A few weeks after the first release a whole bunch of hackers started an Anti-Chrome campaign, in order to make them remove this part from the EULA. I don't know if they succeeded, I didn't follow the newsline... anyway, you should always watch out for what you install
