What is going on with you? Anyway, if you want to try self-hosting on a VPS, make an account on lowendspirit.com and hang out there for a while. There are lots of offers for free or ridiculously cheap VPS there. Like this starts at 25 cents per month ($3 per year):
Open a thread there saying what you’re trying to do, and ask for hosting and for technical help if you need that.
Just use a text editor. I use Emacs org files but that’s just me.
I guess I don’t understand the issues you think you’re facing with straightforward approaches. You probably don’t want it on an internet server, right? Maybe just scrounge an old laptop with no internet connection and set it up with an encrypted disk. Then use it as your journalling box. So you’re fairly safe from network attacks. You might have to worry about someone snagging the laptop itself and recovering the key somehow. Yes there are approaches you can take to mitigate that. I don’t know of any super simple ready made methods though.
Maybe you could try a prepaid credit card from a store.
You’re asking a support question for a provider that most of us here have never heard of. I’d wait a day or two and then maybe open a ticket with the provider.

I remember having to puzzle over the borg documentation a little when I started using it, but I don’t use any tools. I just have a couple of aliases in my .bashrc and that seems like enough.
I don’t understand, what’s wrong with Borg?
I don’t see a plus. It says “FreeOTP version 2.0.6 (48) © 2013-2023 - Red Hat Inc, et al”. But I think I’ve gotten updates more recently than 2023.
I’m using FreeOTP from F-droid and imho it suffices if you’re going to use a phone app at all. The ability to back up OTP keys in principle defeats the concept of 2FA but it’s hard to live without, once you have enough keys. The thing about retain last N backups is hard to enforce without special arrangements in your backup scheme.
I have found gitit easy to install and use though not all that featureful. It uses git as a backing store and there is an apt package for it (apt install gitit).
Nice but doesn’t sound self hosted.
