What is Threema. The Secure Messenger? Description of Threema. The Secure Messenger

Threema is the world’s best-selling secure messenger and keeps your data out of the hands of hackers, corporations, and governments. The service can be used completely anonymously. Threema is open source, allows to make end-to-end encrypted voice and video calls, and offers every feature one would expect from a state-of-the-art instant messenger. With Threema Web, you can also use Threema from your Desktop.

Threema is designed from the ground up to generate as little data on servers as possible. 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 metadata. Threema is fully compliant with the European privacy legislation (GDPR).

Threema encrypts ALL your communications END-TO-END including messages, voice and video 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 users’ devices to prevent backdoor access or copies.

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

Accessibility issueThere is a problem with accessibility for voice-over users When starting recording voice message the sound of VoiceOver changing to other speaker which is used to speaking on the phone.Bluewings83Version: 4.6.2

Needs to be fixed since last updateEver 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!.Tennessee iPad ownerVersion: 3.0
