What is Signal?
Signal is a free messaging and voice chat application. It targets both devices Android as well as in devices iOS, but can also be used via computer. As with other applications, users can send messages, make voice calls, and make video calls. However, Signal focuses much more on the security of its users' data.
How secure is the Signal application?
Your communication via Signal is completely encrypted, which means that only people who exchange messages can see the content of these messages. Even the company itself does not have access to these data.
The application was the first to create the encryption protocol used by other companies, such as WhatsApp and Skype.
What other features does Signal have?
Apart from the fact that your messages are encrypted, there are settings that allow you to choose to disappear after a certain period of time. In addition, Signal does not collect data about them users of. The only information you provide to the application is your phone number and the company is working to find a way to create encrypted contact servers.
The main reason it does not collect data is because Signal is a non-profit organization and not a for-profit company. It does not contain ads, so there is no incentive for users to follow. Instead, it is funded by grants and private investors.
