Highest Encryption Strength
Threema encrypts all your communications end-to-end
including messages, group chats, files and even status messages. You
can rest assured that only the intended recipient can read your chats,
and nobody else – not even us.
Versatile and Feature-rich
Threema makes secure communications easy and fun. You can send photos, videos, voice messages, QR codes, polls and any type of file (PDF, GIF, MP3, DOC, ZIP, etc.).
Guaranteed Privacy
Threema is designed to generate as little data on
servers as possible: Group memberships and contact lists are managed on
your device only, messages are immediately deleted after they have been
delivered. This effectively prevents the collection of meta data
