Found this buried on their blog, source at end.

Secret spy in your device

The scene with Flash Keyboard was definitely among them. The app was actually among the most popular apps on Google Play Store if we look at the download rate, until cyber security companies revealed that the app was stealing users' data without their permission and then sending the info (GPS location, email address and etc.) to various servers located in China, United States and the Netherlands. Once found out Google removed the app from the store.

Another keylogger attack scenario happened with the perfect legitimate Android Keyboard application – SwiftKey that was infected with a Trojan that turned the app into a keylogger.

Anti-keylogger – let’s keep private as private

Anti-keylogger feature for Android devices keeps your private data as private and besides a usual malware scanner and real-time protection that most of the security apps have, the anti-keylogger is an additional layer of protection which is specifically designed to detect and block the keylogger that may be lurking around in your device.

It detects malicious keyboard applications, password managers and SMS applications that track everything you type, even legitimate keyboard applications which are modified by hackers.

Wolf in sheep's clothing

Advanced version of keyloggers have the ability to trick users worldwide, like a wolf in sheep's clothing, in order to get what they want. Simply by putting a nice mask, something that we are familiar with, they are covering their real malicious face. It is always good to download an app from reliable sources and to always review what is the app asking us to do. By simply clicking next, next, next and agree can lead to many unwanted situations.

my not-known beta keyboard app got flagged as keylogging app too, Pandora in the PC Version of Zemana has a lot of false positives too, so nothing suprising.

It seems to have a strong anti key-logger detection and we can expect FPs. Alerting rather than not detecting such PUAs is better at times.
A question is whether it is able to dynamically intercept keylogging or similar attacks without prior static detection of that app. I could not find any article describing the working in details.

In the case of SwiftKey infected with a Trojan, probably the app required special permissions like access to personal data and full internet access.
The first line of defense is always reading the permissions required by an app during its installation, but usually no one does this.
