Signal Private Messenger: A Comprehensive Review

In the era of surveillance, privacy has become a top concern for every internet user. People like to connect with others virtually but with proper privacy measures. This is why messaging applications that ensure privacy and end-to-end encryption are becoming popular these days. Signal Private Messenger is one such messaging app that promises secure and safe messaging.

In this article, we will take an in-depth look at Signal Private Messenger – its features, functionalities, privacy protocols, and more.

What is Signal Private Messenger?

Signal Private Messenger is a free, cross-platform messaging app that has been in the market since 2013. It was developed by Open Whisper Systems, which is known for its robust security protocols. Signal aims to provide an easy-to-use messaging app that ensures end-to-end encryption, privacy, and security.

Signal Private Messenger can be used to make voice and video calls, send text messages, share multimedia files, and more. The app is available for Android, iOS, and desktop platforms like Windows, Mac, and Linux.

Signal Private Messenger Features

Signal Private Messenger is loaded with many features that make it a popular choice among users who prioritize privacy.

End-to-End Encryption:

One of the most notable features of Signal Private Messenger is end-to-end encryption. This means that messages are encrypted before being sent from the sender’s device and remain encrypted until they reach the recipient’s device. This ensures that the message content is secure and safe from any third-party tampering or snooping.

Group Chatting:

Signal Private Messenger allows users to start group chats securely. The group chats are completely private and use the same end-to-end encryption technology as the standard messages.

Disappearing Messages:

Signal enables users to set disappearing messages for individual messages or the entire chat thread. This is useful when discussing sensitive or confidential information that needs to be deleted after a certain period.

Voice and Video Calls:

Signal Private Messenger supports both voice and video calls with end-to-end encryption. The quality of the voice and video calls is good, although the performance may vary depending on the network conditions.

Stickers and GIFs:

Signal Private Messenger also supports stickers and GIFs, making chatting more fun and lively.

No Ads:

Signal Private Messenger is an ad-free platform, unlike many messaging apps that rely on advertising revenue.

Open Source:

Signal Private Messenger is an open-source platform, which means that anyone can audit the code or contribute to the project, making it more secure and reliable.

Signal Private Messenger Privacy Protocols

Signal Private Messenger takes privacy very seriously. Here are some of the privacy protocols that Signal implements to ensure that users’ messages, data, and information are secure and safe.


Signal uses end-to-end encryption to secure users’ messages from any unauthorized access. Encryption ensures that only the sender and receiver can access the conversation, preventing any third-party access.

No Backup:

Signal Private Messenger does not provide any backup for chats or multimedia files. This means that users cannot restore their chats if they switch devices or lose their data. While this may seem inconvenient, it is a measure to ensure that no one can access chats or files, even if the device is compromised.

Disappearing Messages:

As mentioned earlier, Signal Private Messenger allows users to set disappearing messages. This means that once the message or thread is deleted, it cannot be recovered.

No Metadata Collection:

Signal Private Messenger does not collect any metadata or log data, such as call or message duration or IP logs. This further protects the privacy of Signal users.

No Tracking:

Signal Private Messenger does not track users or collect personal information, such as location data, user contacts, or any other data that could compromise user privacy.
