Hey! Yes, it takes root and sets up everything needed. Nothing happens to server if you stop paying, I will be just emailing you and asking what we could do better :) You won’t be able to create apps or add more servers until you resume payments though, but nothing gets locked out breaking your apps etc.

In fact you can add a server through custom server option, then remove it from appliku and remove appliku keys. Free approach to quick server setup :) Appliku doesn’t leave any trace or back door or additional software on your your server. Only ssh authorized keys.

Also none of your data except for build logs and everything related to configuration is stored on our servers either.
