Now it would appear that the software has been found in Apple’s iOS, it was discovered by iPhone developer @chpwn, although it apparently isn’t as bad as the versions of the software found in Android devices.
Importantly, it does not appear the daemon has any access or communication with the UI layer, where text entry is done. I am reasonably sure it has no access to typed text, web history, passwords, browsing history, or text messages, and as such is not sending any of this data remotely.
It looks like the information logged in Apple’s iOS is limited to phone call activity and location data, if location services are enabled, and it can be turned off by going to Settings > General > About> Diagnostics & Usage > Don’t Send.
