Everyone knows that it is important to have secure conversations, and lately many services have begun to focus on encryption. There are plenty of alternatives for you, if you are looking for a secure chat app, and WhatsApp and Signal are two of the most well-known ones. Let’s see what are the differences between.

Data privacy

End-to-end encryption is something that they both support, and this technology is something that has become necessary nowadays. With encryption, no one is able to see the messages, except for the sender and the receiver.

Basically, no other person is able to see the messages while they are on their way to the receiver, which is something that has made chats more secure. Both WhatsApp and Signal use the same type of encryption, but there is a slight difference.

Metadata is also a factor. Metadata reveals other details, such as the receiver of the message, and when the message was sent. In this situation, WhatsApp does collect some information, including contact information, device information, and even your location if it is shared. Additionally, chats can also be backed up.

Meanwhile, Signal does not store anything besides the essential data, like your phone number, your profile information and random keys. Your IP address is only stored while you send a message, This is obviously an advantage.


While Signal might be more private, WhatsApp beats it when it comes to features. This might actually be one of the reasons why WhatsApp has to make some small compromises when it comes to security. With WhatsApp you can see when someone is typing, block contacts, mute conversations, send all kinds of files, and many others.

Signal also comes with many useful features, but it definitely lacks some of the things that are available on WhatsApp.
