I am using ucbrowser from many years it dint gave me any trouble but if be talk about pravicy it is not good and friends they will tell that they will save the data and they will block the ads this all are fake friends because I have useing this from many days and I am sure that they will not save any data or block any ad or any thing and even they will force us to download many other apps so that we will get money or gifts or something else after downloading we will not get anything friend they will tell us because they money from those apps.
