The level of blissful ignorance here is astounding. Kingroot only works with a network connection. Why is that? Because it's a data miner that sends all your data to unknown and unaccountable persons in China. The IMEIs are harvested and used to clone gray market devices, and sold to shady operators so that stolen high-end devices that are blacklisted can be activated again. Your e-mail and contact e-mail addresses are sold to spammers for spoofing purposes. Just think, over the next few years people will be getting their porno spam with your return address, which will quickly become blacklisted, resulting in perhaps your own e-mails never reaching their destinations. Any other data they can get, such as anything you happen to type into a form or message, no doubt will be used appropriately. Seriously, wake up people.
