Linux Kodachi
Kodachi Linux has most, if not all, of the ingredients needed to make a dish of anonymity.
For starters, this is the live operating system. So yes, it can be run directly from USB drives or CD/DVD drives.
Then everything is routed through Tor And VPN.. This, of course, masks your location and general internet activity. Automatic DNS encryption is also offered by default.
Oh, it also has dozens of pre-installed privacy tools. These include Tor, Exif Cleaner, OnionShare and more.
And yes, every time it turns off, all data that may be related to your use of the system is deleted.
Although it does not write data to the hard drive (for obvious reasons), it allows you to create additional permanent storage. This allows you to decide which data will not be deleted in system reebot.
Additional full disk encryption is also available. I like its “Nuke" feature! So, when you choose full disk encryption, you will need to enter the password every time you access the system.
"Nuke” is trouble-free. This is the second password that you can set. Suppose there is a gun to your head and you have to unlock your system, you enter the nuke password. All the files, data and everything else in your system just disappeared, poof!
