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 and offers every feature one would expect from a state-of-the-art instant messenger. The app also allows to make end-to-end encrypted voice, video and group calls. Using the desktop app and the web client, 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).
ROCK-SOLID ENCRYPTION
Threema end-to-end encrypts all your communication, including messages, voice and video calls, group chats, files, and even status messages. Only the intended recipient, and nobody else, can read your messages. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on the users’ devices to prevent backdoor access or copies.

Придбав та користуватися не вистачило терпіння
Наче непоганий застосунок та велика кількість багів, недопрацювання, відрадили мене від ідеї подальшого користування цим додатком. Може якось згодом буде краще. Поки видалив мобільну та десктоп версію.
Більшість функцій працює, але бувають перебої. Відео звʼязок працює не завжди.
Вердикт: додаток сирий для вирористання. Можна поставити подивитися і погратися.
Дуже погано як для платного месенджера
Чому так погано працює платна програма? чому такі всраті голосові? чому не можна видалити надіслане повідомлення у себе і у співбесідника? Чому час від часу просто не приходить повідомлення без наявних причин?
Пожалуйста добавьте гиф, и больше эмодзи.
Я настоятельно требую этого. Владиславу так больше нравиться со мной вести диалог 😂
Autodelete
Please make autodelete messages🙏
Пока плюсов не вижу.
Разроботчики,а вы не думали что человеку нужно будет поменять телефон???!!!Чаты нужны будут все !!!

Потрібно трішки допрацювати месенджер, в плані зручності користування, не в плані безпеки.
The worst messenger ever
The worst messenger on PC, the versions are very limited and the standard features are poorly implemented. Terrible compatibility
Ukraine
Отличный мессенжер, не требует привязки к email, или номеру телефона. Проверен в разных ситуациях где viber и другие мессенджеры проигрывали. Просьба к разработчику добавить отправку сообщение по времени.
