What's going on in background?

Did you know that mobile phone manufacturer collect your info without notifying you? Did you know your mobile phone may check in to manufacturer's server automatically and frequently? It sounds terrible but it did happen.

After doing a simple research I found this in the internet. I think it very much answered your question unless you have further deepdive study of it.

HTC Checkin
Overview
HTC Checkin is the service responsible for “checking in” to HTC. Recovery/Boot/Kernel Logs, Apps Updated/Crashed and mobile data amounts are sent off automatically. The service also checks for Over-The-Air Updates.

Under no circumstances should they collect personal data. No matter what the excuse is.

What I want to emphasize is…They have to ask for our permissions first.

so u mentioned about zip code,Area,IMEI, Locale,Timezone,Device S/N,Model number..and Location being sent up. but which part is personal information?
