The normal account (dafault) is the only monetized option, giving 100mb of free space.

I did a quick check on the self hosted option in the beginning and same, seemed too convoluted and decided to stick with the local method, since I tested it (turning phone WiFi off) and it was still syncing (via tailscale)

On the upside, I tested the import/export features and seemed rather solid, so you can always create a new local account (save the seed phrase!) And bring your stuff back into it.
