ha, well, nothing to hide to that extent.
I don't know about Keep, but it's another app, which is kind of my point - I already use Gmail.
There's also cli access to Keep. And Google keeps on improving integration of mail,calendar,tasks and keep.
> Keeps them quite hidden / private / secure
Not hidden from Google obviously :) At that point, why not just use Keep at that point to get proper support for notes?
