The CyanogenMod team today announced that they will no longer support WhisperPush with CyanogenMod 13. In addition, it will put an end to all WhisperPush services from February 1, 2016, which means that the service will stop working for all CyanogenMod users running CM10.2 and higher.

In its announcement, the CM team states that while they are still “very big proponents of the secured messaging platform,” maintaining and implementing their own secure server led to quite a bit of issues, which was a huge factor in their decision.

If you are still using WhisperPush, the CM team recommends you to unregister your number by going into Settings -> Privacy -> WhisperPush from your Android device. If you don’t have access to your Android device, the CM team will automatically unregister your number on February 1. For WhisperPush users, this means that their messages will be sent as normal text messages on and after Feb. 1, 2016.

As an alternative, the CM team recommends using Signal. The app combines the capabilities of TextSecure and RedPhone into an open source app, which has been developed by Open Whisper System — the same team behind WhisperPush in CyanogenMod.
