In which case you should just write them on index cards and put them in your desk at home, which is what I do.

Why the hell would you "self-host" a cloud service?
Almost any server can be "cloud service". There are several interesting solutions to the problem "I need to access a Git repository over the net" in "the cloud" or otherwise.
