lose privacy compared to what? you are assuming they are collecting your data not just compressing it on the fly. do you realize the resources needed to log and store ppls data streams. the caching needed on there servers is temporary. highly unlikely they log and store it. if you are not using a vpn or privoxy with proxy chains in general with or without tor then you have no privacy anyway. if you use those methods with uc browser then you are just as invisible to them as you are to your isp because your ip is unknown and packets are encrypted.
