How do I sign up?
Threema allows a multi-level registration. Who would not reveal about themselves, can log on with a few clicks after installation. Without cell phone number, no email address. Even the display name is optional. However, the user gets a Threema ID, which is composed of numbers and letters (for example: E45F66A77D). This does not allow any conclusion as to the identity. The name is not displayed for a chat. And friends can not find one in their contacts as Threema contact.
More data are therefore useful.
This is also a critical point because Threema searches only on request, the own contacts for possible Threema chat partners. There is not found, who has signed up without mobile number or email address. Therefore, in the application, these are deposited with what seems to make sense. Threema then sends a code via SMS, or a confirmation link by e-mail to verify itself final. Only then the user becomes a full Threema users.
What do the three dots mean?
The three dots in the logo can also be found in the app again. For example, in the chat window when the name of chat partner. Or when the information about a contact under "Security Level". They provide information about how safe it is to actually chat with the right people. If you have registered without personal information that is at the other also displayed with a red dot. Low security level ie.
Who has, however, through the way of verification by cell phone number and e-mail, is considered "safe" and is evaluated with two orange dots. The full three green dots get contacts that were entered using the scan function. For this purpose, each Threema users a personal QR code in his profile that can be scanned by friends with their smartphone. This is the contact than 100% verified entered in the address book.
How does Threema?
In everyday life, Threema does not feel different than WhatsApp, Line, Facebook Messenger or most of the other messenger. The basic functionalities within the chat feature are nearly identical. Whether text, pictures or videos, mail and display of information proceeds equal. Also the chat window is similar.
Voice messages (like WhatsApp) can be personalized with Threema but will not ship.
Is Threema really safer than WhatsApp?
The primary aspect of safety is Threema on the communication. So-called end-to-end encryption to protect text messages, pictures, videos and GPS locations from prying eyes. That is, all data are sent, encrypted, to the reception of the preparation.
With WhatsApp texts are transmitted in the so-called "plain text" and sent through the network. Threema converts the texts prior to shipment to unreadable number-letter-chains to (for example: "334nnh445nj5nn5eebddd3dc3"). At the receiver, these chains are then converted back into readable text. So the Threema conversations are much safer.
Is my data safe so?
The end-to-end encryption method makes at least the Threema conversations safer than those in WhatsApp & Co.. Remains unclear, however, what data is stored on the servers of Threema. Since users may trust or distrust as with other messenger services even the creators of Threema to the same extent. Can be assumed as certain that the credentials of the user are stored in the Swiss.
While there was still hooked on Threema?
With all the enthusiasm for safety - some Threema functions are not fully developed yet. So came in a test, the confirmation SMS never, while it worked without problems in another device.
It is also not clear when and what information is displayed on a chat partner. Even fully-registered users are displayed in parts not by name, but only with their ID.
Groups can be created but not processed at Threema though. That is, only three people are in a group, it is these three people. Add or delete can be no one individually. Some users also report it to have been added in a large group, then to inadvertently other (foreign) to find group members in the contacts on the phone - as cryptic IDs!
Is there a guarantee that no group buys Threema now?
The short answer is: No! A warranty does not exist. It can not even speculate. WhatsApp founder January Koum has only a few months ago declared a sale would definitely not up for discussion. Now the messenger is part of the Facebook universe.
The major industry players have just as much "play money" that nothing is impossible. Of course, Facebook already had a Messenger. Google also (Hangouts). Likewise, Microsoft (Skype). This does not mean that now remain, all other messenger forever independent.
