I have a couple of hundred devices connected to it now, and the _only_ cloud integration I use is Spotify, for obvious reasons; I have been careful when buying smart things that they're completely offline, and anything I buy that _is_ smart but isn't offline-only gets hobbled into a "dumb" appliance; e.g. my new dishwasher has "smart" stuff, if I connect it to Wi-Fi, I found the maintenance menu and disabled the network interface entirely and it's just a regular dishwasher now, which is how I like it.
