I pay Bitwarden the tenner a year as I have no reason to distrust them and they’re definitely providing a more reliable, securer service than I can self-host.
I also do an encrypted export once per week and store that export to an encrypted cloud based service and an encrypted USB stick. Takes 2 minutes.
There was some talk awhile ago of the devs maybe extending feeds beyond Communities to Posts and Comments too but I don’t think it ever got off the ground. Would certainly be way easier to do what I think you want if they did exist.
