Description

Threema is the world’s favorite secure messenger and keeps your data out of the hands of hackers, corporations and governments. Threema can be used completely anonymously, allows to make end-to-end encrypted voice calls, and offers every feature one would expect from a state-of-the-art instant messenger.

PRIVACY AND ANONYMITY
Threema is designed to generate as little data on servers as possible – this is a core part of our concept. Group memberships and contact lists are managed on your device only, and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including meta data. Threema is fully compliant with the European privacy legislation (GDPR).

HIGHEST ENCRYPTION STRENGTH
Threema encrypts ALL your communications END-TO-END including messages, voice calls, group chats, media files and even status messages. You can rest assured that only the intended recipient can read your chats, and nobody else – not even us. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s devices to prevent backdoor access or copies.

COMPREHENSIVE FEATURES
Threema is not only an encrypted and private messenger but also versatile and feature-rich.

• write text and send voice messages
• make voice calls (requires iPhone 5s / iOS 9 or above)
• share videos, pictures and locations
• send any type of file (pdf, animated gif, mp3, doc, zip, etc.)
• create groups
• conduct polls with the unique poll feature
• choose between a dark and a light theme
• quickly and silently reply with the unique agree/disagree feature
• verify the identity of a contact by scanning their personal QR code
• use Threema as anonymous instant messaging tool
• synchronize your contacts (optional)

FULL ANONYMITY
Each Threema user receives a random Threema ID for identification. A phone number or email address is not required to use Threema. This unique feature allows you to use Threema completely anonymously – no need to give up private information or to open an account.

TRUSTED CONTACTS
We let users confirm trusted contacts with a QR code or a key fingerprint to prevent man in the middle attacks.

INDEPENDENT COMPANY
We are a 100% independent and self-financed company in the heart of Switzerland with its own servers and in-house software development. Switzerland is a country with some of the most user friendly privacy laws in the world.

Great but behind on features

secured2k

This app is great for secure messaging and anonymity.

I wish this app used a in-app purchase model so it could be downloaded for free to increase the user base. They could then charge an in-app purchase for features like voice calling, group chat, or other features that could be limited but allow for basic secure messaging for new users.

However, for being a paid app, it seems to lag in features compared to competing products. I hope they add or fix some of these items:

- Perfect Forward Secrecy on the end to end layer
- self destructing and deleting messages
- video calling
- allow the user to do other messaging while a call is in progress.

the best no question about that.

first rule: you get what you pay..so if its free its crap or screwed you by the T&C.
i like to see more support for the apple watch so that u can actually write a new message without the use of an notification of an unreaded message by the phone from the watch.

Needs to be fixed since last update

Tennessee iPad owner

Ever since the last update the voice message recording has a bug. It records super silently and you have to pretty much hold the speaker right to your ear to be able to understand. Even if the volume is all the way up. Please fix that issue! It's very annoying!
