Re: What does this app do?
HTC, Samsung, Sony all other company has same Apps. They are default. They need registration with your device. If you don't want update select don't update from option of the software. When you contact with HTC for any problem they will connect your device through these apps and update your set also security option. Update is good for your device. And You have the one of the best device. Try to set Google account, Google + account, And Other Social Network accounts privacy setting. And it is best to use Device Default browser. Not other browser.
