What is Threema Safe and how do I enable it?

Threema doesn’t store your data on a central server, your data is only stored on your local device. This provides the best protection against unauthorized access.

To prevent that your Threema ID, your contacts, and your groups (as well as other data and some settings) are lost if you ever happen to lose access to your device, Threema Safe regularly creates an anonymous and encrypted backup of this data on the Threema server or on another server of your choice.

Threema Safe is platform independent. No matter what Threema version (Android, iOS, or Windows Phone) was used to create a Threema Safe backup, it can be restored on any platform. This allows to conveniently transfer basic Threema data from one platform to another.

  • Android
