@adriangadientbruegger it sure where you get your information from, but Signal is more secure than Threema. See [1] “Signal is better than Threema because Signal has Perfect Forward Secrecy on the end2end-Layer, which Threema does not. This means that in Signal, every message has its individual encryption key, so even if the Signal server would collect all messages sent, they couldn't decrypt”@AboutSignalNL
