What is Signal, what is the app for and why should you use it?

Signal is an instant messaging platform with particular attention to privacy and security. The app of the same name acts as the official client and allows access to their services. Signal is a non-profit foundation that aims to provide users with a stable, open-source and tracker-free alternative to WhatsApp. Signal can be used on Android and iOS, as well as on Windows, MacOS and Linux.

Below we list some of the key features of Signal:

  • Secure and private messaging between two or more users. Signal allows you to send text messages to other users. This data transfer is end-to-end encrypted.
  • Securely and privately send files between two or more users. Signal supports sending a variety of additional formats, such as images, videos, documents, or voice memos. It is also possible to send contacts and location. Everything is transmitted using the same security system used for sending messages.
  • voice and video calls. This application also allows you to make calls and video calls between multiple users. As in the previous cases, this communication is point-to-point encrypted.
  • Creation of groups with up to 1000 participants. Signal groups work similarly to WhatsApp and Telegram groups. It is possible to define a user as an administrator and invite other users via a link. You can also customize the group icon or add a description.

In fact, Signal’s features are pretty common. So why should you use them? The main reason why this app is recommended is its high level of privacy protection and because it presents itself as a safe environment. Although the direct competitors offer similar security systems for the transmission of information, such as B. a point-to-point encryption, the signal app does not collect any personal data and also does not send it to a server for analysis. And that’s possible even though it’s a full-fledged messaging app with all sorts of features.
