You can physically bring data from one side to the other on a memory stick.

But in my machine data does not move from the personal side to the internet side or vice versa. You must physically carry it around to the other side’s USB port.

You will not have any of your personal side data read, copied or altered by any malfeasor on the internet.

You work is safe and private UNLESS you decide to carry it round to the internet side of this machine.

You could get my simple machine, or pay huge sums to companies that need to update their program in your machine every day to stay safe against all the bad actors out there.

My machine is cheap. Their system is extremely costly, risky, and inconvenient.
