@Bob This is a really good question. At a bare minimum you could continue to use Lockitron with all of the same “keys” you’ve issued assuming we don’t remove our app (or display a screen blocking you from using it). You would be unable to issue additional keys or update the firmware. Logging would also cease to function. I have to check on Sense.
We’ve hosted Lockitron servers for 6 (yes, 6!) years now - if we were to make any changes to the service we would want to give users ample forewarning of that.
While there are a lot of factors outside of our control, our personal belief is that we would like to let users to continue to use Lockitron with some functionality even if the cloud portion was shut down. I think it will take more than a forum post for me to formulate we can and can’t commit to here
