What is the Threema app?

What is the Threema app?- Threema - The Secure Messenger
Threema is a proprietary and paid end-to-end encrypted instant messaging service that allows users to send messages, and make phone calls and video calls in secure conditions. Your data will be kept from hackers, corporations, and government intrusions by being encrypted even in transit. Each user will receive a random Threema ID without providing personal information or signing an account. One of the reasons Threema has such a high level of security is that the developer, Threema GmbH, is based in Switzerland, so it must comply with the standard protection rights of Europe’s endless advisors (GDPR). Currently, the app is priced at $4.99 and supports numerous languages: English, Basque, Czech, Dutch, French, German, Italian, Japanese, Simplified Chinese, etc. It’s compatible with Android 4.0 and above, iOS 6.0 and above, and Windows Phone 8 and above.

Highlights of Threema


Encryption- Threema - The Secure Messenger
With full-time E2E encryption and an absolute minimum of unencrypted data to corporate servers, it’s definitely a secure messaging app. Anything stored on the company’s servers is temporarily there. As soon as a message is sent, the message itself, along with associated metadata, is deleted from the server.

Message Protection

Threema allows you to protect your private chats and hide them from the chat list on the Threema home screen so that no one else can see your confidential messages. Notifications you receive for private chat messages also don’t have message previews. To do this, press and hold a conversation you want and select Mark as private. You will then be prompted to create a PIN, which you will have to enter each time you want to display a private chat.

Data Saving

Data Saving- Threema - The Secure Messenger
Threema stores your data on the relevant devices. The system does not need to store a minimal amount of metadata on its servers to receive messages delivered to their destination. When that happens, the metadata is removed. Data stored on the device is AES-256 encrypted for maximum security. This includes media files that have been sent over the Threema network.

Media Library

The media library is also equipped with image recognition so you can search for photos by entering certain keywords. This saves you the trouble of searching through countless images on your device. Because the recognition is done locally, the image never leaves your device, but if you’re not comfortable with this feature, you can choose not to enable it. With global search, you can search across all your chats at once, instead of searching individual chats.
