Paper jounal may not be backable up, but they are not affected by bit rot, cannot be tracked or detected by any means, they are partially or totally destroyable, and helps freeing the pressuring throughts from your head, so you would be less vulnerable under torture.
Also, one can log what you type on a device even before it is encrypted (if we assume the worst scenario). So i think keeping a paper diary, even with the comfort flaws, stay the safest option (if you hide it well and doesn’t reveal its existence).
What i’m writing on.
A “smartphone”,
the name we gave to a rectangular rock with billions of mechanisms 10 000 smaller than the width of a hair, capable of aligning by billions of operation per second numbers in such precision that we get the feeling of seeing colors and images and text,
capable of emitting precise electromagnetic waves to transmit “messages” around the world, by a perfectly organised system called internet,
capable of representing 3d scenes, taking pictures, giving its localisation, and entertaining you, keeping millions of book in the palm of your hands,
Such miracle stone that we use to consume brainrot, spy on people, and throw in the trash 2 years later because it, for once, got a flaw.
