I've personally never actually used any of the pebble cloud based services for mine, as I never trusted them with my data. I use GadgetBridge to pair it and manage the apps and update the time, etc. It's been somewhat limiting (GB deliberately doesn't have feature parity with the cloud services), but I definitely wouldn't call it "bricked". That said, I do think I downloaded most of my apps from Pebble's store, so without a backup of the Pebble store, you might be severely limited in your choices.
