Unlike other popular messaging apps (including those claiming to use encryption), even we as the server operator have absolutely no way to read your messages.
Features:
• End-to-end encryption of text messages, images, videos and GPS locations
• Contact synchronization (optional): find other Threema users automatically
• Send images and videos
• Share your location on a map
• Verify your contacts' public keys by scanning a QR code from their mobile phone, all within the app
Threema is Made in Switzerland, and all servers are hosted there as well for maximum privacy.
