I went through this rabbit hole. I liked Mint (I know it wasn't private, but I liked it), I tried Personal Capital / Empower because I had a retirement account with them, I tried Monarch. But none of them had the one killer feature I needed — my wife and I both have individual accounts and we also have a joint account for household expenses. I want to track all of those separately.
The I found Tiller[0]. I've been really happy with it so far.
It basically syncs your transactions to a Google sheet you own. It comes with some basic things like budget and auto categorization based on fuzzy string matching, but because it's Google sheets you can play with it and do whatever you want with it.
But the nice thing is that you can dictate which accounts go into which sheet. So I have two sheets — one for household accounts and one for personal. And I don't need a separate subscription, which would have been required if I used any other service I had looked at. I can't remember exactly how much the subscription was, but I don't remember it being unfair.
