Arya
Arya is a set of small tools one person builds and runs for their own use: a dashboard for the week, a to-do list, and the backups that keep them safe. They run on a home server. There is nothing here to sign up for, and the tools are not offered to anyone else.
One of them, build-me-things backups, copies the owner's own data from that server to a folder in the owner's own Google Drive each night so it can be restored if the server fails. It asks Google only for access to the files it creates.
