Why Threema?

For privacy, freedom, and control, iOS is out. As with Telegram, I advise staying away from the Google variant and highly recommend the Threema Libre implementation for Android. Licenses are not compatible across variants, so stick with the Threema Shop!

The largest criticism levied against Threema:
- 2023010? - Accusation - Three Lessons from Threema - Analysis of a Secure Messenger
- 20230109 - Rebuttal - Statement on ETH Findings
- 20230110 - Coverage - Messenger billed as better than Signal is riddled with vulnerabilities
“While some of the findings presented in the paper may be interesting from a theoretical standpoint, none of them ever had any considerable real-world impact,” the post stated. “Most assume extensive and unrealistic prerequisites that would have far greater consequences than the respective finding itself.”
