Does it exist, some sort of encrypted journal-like app where I can type things which will be forever locked away? In my mind and in a place I can feel confident about, without a doubt.

Pen and paper requires burning afterwards, I don’t think I want to do this.

I know no opsec solution is perfect. I need some sort of outlet. I need some sort of solution.

I was thinking. Maybe, at least, some solution where even though access is non-negotiable, if somebody does get in, I can accept that the entity was already determined enough to end things.

Thanks.

Edit: I should I guess mention the obvious such as encryption and possibly authentication with a hardware security key. Any other features that might be out there I am hoping to hear about.
