Smartphones become popular
As smartphones start to become ubiquitous in the early 2010s, chat apps gradually begin to replace SMS as the de facto standard of mobile communication. However, all chat apps exhibit serious security flaws. Three young software engineers from Switzerland start to build a secure alternative.
“End-to-End Encrypted Messaging Application”
The app is called “End-to-End Encrypted Messaging Application,” “EEEMA” for short. Soon, the three “E”s are replaced by “Three,” and it becomes “Threema.” The founders have no idea about the movement their app is going to trigger.
The number of users increases to 250,000 in no time
The first Threema version is released on December 12, 2012 in Apple’s App Store. A few months later, the first Android version is released. The impact is tremendous; the user base quickly grows to 250,000. Threema has caught the spirit of the age.
Snowden revelations shock the world
By revealing the Prism surveillance program in mid to late 2013, Edward Snowden drastically raises the public’s awareness of privacy issues on the Internet. The scale of the global surveillance is alarming. All kinds of online communication have been intercepted. Concerned Internet users fundamentally question the communication channels they have been using to date.
More privacy scandals deepen the distrust towards established communication channels
After the Snowden revelations, various other privacy scandals (especially the alleged wiretap on chancellor Merkel’s cell phone) and numerous data leaks have a negative impact on the public’s trust in the current communication channels but a positive and lasting effect on Threema’s downloads.
Facebook acquires WhatsApp: Threema’s user base grows exponentially
After Facebook’s acquisition of WhatsApp in February 2014, Threema experiences a greater boost in growth than ever before. In search of a privacy-friendly instant messenger, many smartphone users turn to Threema. In a few weeks, the number of users climbs to 2 million.
The company is run from the kitchen table
The founders are caught off guard by the enormous increase in downloads after the WhatsApp acquisition. In night shifts, they answer press inquiries, handle support requests, develop the app, and complete the most important business tasks.
Threema GmbH is established
Establishing a startup was planned for quite some time. In spring of 2014, it finally happens: The Threema GmbH is founded in Pfäffikon SZ. A team of experienced software developers is continuously working on refining the Threema app.
Steady downloads and venture into the business sector
Since the company’s establishment, the app downloads have remained steady. Several thousand smartphone owners purchase the app each day. In 2016, the Threema GmbH hits the mark once again with Threema Work, a chat service specifically tailored to the use in organizations.
Threema is and shall remain a statement for privacy
To this day, its comprehensive security and the unparalleled privacy protection set Threema apart from conventional instant messengers. Threema is more than just a chat app. Threema is a statement. A statement for privacy.

Threema started life as an abbreviation: “EEEMA,” for “End-to-End Encrypted Messaging Application.” The three “E”s were a bit unwieldy, so it became “Threema.”
Threema is the world’s best-selling secure messenger. It sets itself apart from others in the following respects:
- Guaranteed privacy: Threema is designed to generate as little data on servers as
- Full anonymity: You are not forced to provide any personal information
(such as your phone number or email address) in order to use Threema.
- Open source: To provide full transparency, the Threema apps are open source.
Anyone knowledgeable enough can confirm Threema’s security on their own.
- Optional contact synchronization: It’s not necessary to grant access to the address book in order to use Threema.
- Comprehensive encryption: In Threema, all your communications are end-to-end
encrypted – not just text messages and voice and video calls but also group chats, media files, and even status
- Rich functionality: Threema is versatile and feature-rich.
Find out how Threema stacks up against other messengers like WhatsApp, Signal, or Telegram in the comprehensive messenger comparison.
In contrast to other messengers, your identity in Threema does not depend on a phone number. Each Threema user gets a randomly generated, 8-digit Threema ID when starting the app for the first time. This ID is your unique address in Threema and makes it possible to use Threema completely anonymously, without disclosing any personal information.
Your Threema ID is just one of two components that make up your identity in Threema. The other one is the so called key pair (consisting of a public key and a private key) which is essential for the encryption. Your Threema ID is permanently tied to your public key. While the public key is sent to Threema's servers to be distributed to your chat partners, the private key remains on your device where it is securely stored. All messages directed to you will be individually encrypted with your public key on the sender's device. They can only be decrypted with your personal private key.

Threema is fully supported.
Threema is not supported.
* If you are using Threema with an Android Wear smartwatch or an Apple Watch, you can read message previews, see chat pictures, agree/disagree to incoming messages and answer messages using dictation (or using Scribble on an Apple Watch).
Threema is currently available in the following languages:
- Basque (Spain)
- Brazilian Portuguese
- Chinese (traditional and simplified)
- Slovak (Android)
If Threema doesn’t support the device’s system language, the user’s preferred languages (as defined in the system settings) will be taken into account. If these languages aren’t available in Threema, English serves as fallback.
Is Threema not yet available in your language? Support the translation here:
Yes. Both servers and offices only use energy from renewable sources.
The development of the Threema apps and the maintenance of the server infrastructure generates costs. The app price covers these costs.
If we wanted to offer our apps for free, we would have to monetize user data, which, of course, would totally undermine Threema’s purpose (i.e., to protect the users’ data and privacy). Besides, Threema is designed from the ground up to only generate as little user data as technically possible, so there’s next to no user data to begin with.
