The disregard for privacy of this company is so severe that I highly advise against adding this. If you place freedom of choice higher than ethical freedom (and I know many people do), then at least add a warning in the software center that this application may be compromised and be used at your own risk. Indeed, I believe there is sufficient evidence to say it is actual malware, that is, an application capable of logging everything that is typed while Sogou Pinyin is activated as an input method editor. This literally includes everything. You don't want your passwords out there, do you? Sadly, this is the most popular IME in China.
