Description

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. PRIVACY AND ANONYMITY 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). HIGHEST ENCRYPTION STRENGTH 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. 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 and video calls (requires iPhone 5s / iOS 10 or above) • Share videos, pictures and locations • Send any type of file (pdf, animated gif, mp3, doc, zip, etc.) • Use Threema Web to chat from your Desktop • Create groups • Conduct polls with the 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) SERVERS IN SWITZERLAND All our servers are located in Switzerland, and we develop our software in-house. 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. OPEN SOURCE AND AUDITS The source code of the Threema app is open for everyone to review. On top of that, renowned experts are regularly commissioned to conduct systematic security audits of Threema’s code. NO ADS, NO TRACKERS Threema is not financed by advertising and does not collect user data. SUPPORT / CONTACT For questions or problems please consult our FAQs: https://threema.ch/en/faq

  • Auto delete, c’mon fellas

    Here’s the thing: Auto delete might not be a 100% reliable (/ safe) feature, but not being able to delete messages is certainly 100% unsafe. Inform your users by a disclaimer and go on with it, not hide behind this silly pretense and cause negative reviews by people that either think they know better or are frustrated about messages that are forever saved on someone else’s phone. Just saw your app featured on The Terminal List, so much potential stopped short.
  • Want a refund- not transparent

    I want a refund, they are not a transparent company. They are suppose to be a opened source company but now have private investors. Do they let their customers know, no. You could just a app such as signal for free and have the option to have the messages auto delete and delete messages for everyone.
  • No gifs

    Other than not having gifs to send it’s overall a well designed app.
  • There are a bunch of annoying little “bugs”

    For example: you can’t listen to a voice message and type a reply while still listening. Because it opens a little window where it plays the voice message. This is not the case with the android version. Why is the ios version so annoying? Also, why don’t I get a notifications that a message wasn’t sent? Why do I have to leave the chat open until everything has sent? Which is also pretty annoying.
  • Great messenger, with limitations

    Really needs more reactions options. The ability to “like” or HEART a message would be greatly appreciated. This feature is used by empaths on other platforms extensively. A thumbs up doesn’t cut it.
  • 1 thing missing…..

    SELF DESTRUCTIVE MESSAGES IS A MUST. Other than that the app still deserves five stars because it is by in large the most trustworthy secure messaging app. Signal makes you linke phone number, Not Threema! You can use it totally anonymously. Clear pay for play profit motive. Still deserves 5 stars but please integrate Self destructive messages!
  • App keeps getting better

    The last few updates have made it even better. Please add stickers though. It’s the only feature I and my family still want from WhatsApp. Thank you

    Great idea, poor execution
  • Please fix the issues with Pinyin IME

    It’s definitely one of the best secure messenger apps out there, ticking almost all the boxes. However, there is a usability show-stopper issue for Chinese-speaking users who use Pinyin input method. I’ve opened a support ticket (#893858), but apparently this won’t be resolved anytime soon. We might be a tiny user base, but PLEASE.
