Looks good.

An important question: can we sync it with our own method (e.g. Dropbox or SyncThing or whatever) or is there a hardcoded sync to the company's Cloud?

It's a matter of privacy and freedom to move the data as we see fit.

The sync engine is proprietary, so you can't use your own provider. We wanted very tight control over syncing to achieve our goals with speed and shared lists. I totally understand your concern, though.

For what its worth, all of your data is stored locally in a sqlite DB. You shouldn't edit this DB or syncing may not work, but you should feel free to read from it if you'd like ~/Library/Godspeed/godspeed-db.sqlite
