Secure Contact via Threema

End-to-end encrypted

For confidential communication, I use Threema. Unlike conventional messengers, Threema does not require a phone number and stores no metadata on central servers. All communication is end-to-end encrypted.

How it works:
  1. Install Threema (Android, iOS, Desktop)
  2. Scan the QR code above with the Threema app
  3. My contact will be added automatically with the highest verification level (three green dots)
  4. You can send me a message right away
