realistically there is nothing that is private or hidden. I am convinced that everything is bugged and has been probably for longer than we will accept. The tech being used is beyond what most can imagine and it is not leaked or revealed or seen unless it is permitted. They have never operated under mans laws or constitutions and there are no rights. Anything a birth certificate person says or views can be held against them - if the rulers choose. This leads people to give up and permit surveillance which is consent - mass consent permits the rulers to advance their plans unchecked. There is strength in numbers. When masses adopt forbidden but harmless practices, the rulers dont completely destroy everyone or the system to prevent the practice, but they do set some examples - prosecute a celebrity who has not played ball - they accuse them of tax evasion or worse. 
tax evasion could be proven for almost every person because of the ways the tax codes are.  I would say the more people that use a work around, the safer they are but there is no safety. I would like to figure out how to use vpn. I began researching it but gave up when I was told it wont be secure.
