[Swlug] alternative to google account

[bascule]

i've just received brother in laws old phone, way better than mine!
but not having a google account and running lineageos, transferring some stuff 
is a pain.
is there an alternative to goggle account that can store locally on my server, 
i thought nextcloud might but that only seems to have specific apps for sms 
and files.
on my phone i have notes app, an app for fuel economy etc. 
i'd like to be able to back up all that stuff to a local account and then just 
restore it on a new phone.
is this a thing?
