Yeah, no way I'd ever trust something like this if it wasn't on hardware I control.

You can't 100% trust some company to secure something this personal, but you know that you won't one day sell your personal diary to some ad firm.

Plus, privacy isn't even the biggest concern. What do you do when the company hosting it goes bust? Or simply decides to not support it anymore, or randomly increases the price? The server in my basement has way less uptime than AWS, but I control what services it runs, forever.
