Google confirmed to the verge that it took down totok the first time for violating unspecified policies. Google did n’t provide any explanation as to why.

totok is a messaging app that promised’fast, free, and secure’ messages and calls. Shortly before its removal, the app was one of the most-downloaded social apps in the US.
