... this is an open source federated app. There is NO reason you can't run your own instance that you control and back up that participates in the network. IF you don't want to pay for expensive hosting, but want it to be always on, then throw it on a raspberry pie and run it from home.

also, because it's federated, all the data you add is backed up on all the other instances that federate with yours. It isn't easy to recreate from their copies, but it's not lost.
