Free messaging service
Signal is a free and open-source messenger app for Windows devices. This program allows you to send secure and instant messages. All messages and calls are encrypted by default so that only you and the recipients have access to the information.
Privacy is a standardAnyone who uses a messaging service such as Whatsapp, Telegram or another is concerned about security. Are your messages truly private? Are your calls secure from eavesdroppers
Signal is the next evolution in instant messaging. It offers many of the same features and privacy protections as other instant messaging services. Signal is endorsed by top professionals in the world of internet security and social media. Signal uses state-of-the art conversation encryption.
Open-sourceSignal claims to be the most secure messaging service available. This is a large part of how it works. Signal (the company), as an independent nonprofit, is free from interference by any major corporations. Signal (the product) can be freely accessed as open-source. It's peer-reviewed, funded entirely by donations, and grants.
Signal could be the right choice for you if you don't like the idea that Whatsapp is tied to a company known for sharing user data. Signal offers all the features you would expect and more. Your data is secure and protected.
Messenger featuresAll you need to send voicemails, texts, and make voice and video calls is your phone's data line. Signal is free and you don't have to pay any additional fees. You can share and create stickers to personalize messages and group chats.
Signal uses a "safety number" to verify chats. It is a unique number that must be verified before you can send any messages. Signal will notify you if someone attempts to access a conversation that they don't have permission to.
Secure and reliable messenger serviceSignal works the same regardless of whether you use it as a standalone mobile application or via its desktop software. Signal could be the secure messaging service that you need if you are concerned about how large companies use your data.
