Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including meta data. Threema is fully compliant with the European privacy legislation (GDPR).<br><br>HIGHEST ENCRYPTION STRENGTH<br>Threema end-to-end encrypts all your communication, including messages, voice 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 user’s’ devices to prevent backdoor access or copies.<br><br>COMPREHENSIVE FEATURES <br>Threema is not only an encrypted and private messenger but also versatile and feature-rich.<br> <br>• write text and send voice messages<br>• make voice calls<br>• share videos, pictures and locations<br>• send any type of file (pdf, animated gif, mp3, doc, zip, etc.)<br>• use Threema Web to chat from your Desktop<br>• create groups<br>• conduct polls with the unique poll feature<br>• choose between a dark and a light theme<br>• quickly and silently reply with the unique agree/disagree feature<br>• verify the identity of a contact by scanning their personal QR code<br>• use Threema as anonymous instant messaging tool<br>• synchronize your contacts (optional)<br><br>FULL ANONYMITY<br>Each Threema user receives a random Threema ID for identification.

User reviews affect conversion to installs and app rating. Featured and helpful reviews are the first to be noticed by users and in case of no response can affect download rate. This is why it is highly recommended to reply to them.
Images from yesterday were not delivered and appear still sending. However images from today were sent. I don't know how to make sure the images are delivered reliably (which should be what it does always) but tap on every message to stop sending and the resend. This is just not robust enough guys, you should improve this! I see your reply and have to say that additional user interaction should not be required to deliver a message. Again, I had to click on every message a second time.
It would be nice to make the option "mark as read" in the pop-up window of the received message as in the Signal. Because it is inconvenient to constantly open the application so that the interlocutor sees the status of the message. P.S. I would like to be able to choose the image compression when sending (as in the settings). Also, there is a strong lack of highlighting messages for saving to favorites (undeletable), as in whatsapp.
Fantastic app, just needs videocall and a bit more stable voicecall, laggs and buggs out sometimes, or don't work at all when you try to call someone. When this is done then I give it 6 stars XD EDIT: It's more that sometimes when I call someone is that we dont hear eachother. But that could also be an human error. :p I just hope for video calls. Then it's absolutely awesome !!
Good choice, if you just care about privacy. When it comes to security, I don't see why there is no burn-on-read feature. Yes somebody could have done screenshots, but also your phone could be infected. In all other cases, it's mostly a bad decision and even more simply not needed in most cases to store a conversation longer than a 1 week or month. Imo this should be enabled by default and only be disabled on user request. Push messages sometimes work and sometimes don't.(power saver disabled)
