Best Encrypted Messaging Apps: Signal vs Telegram vs WhatsApp Privacy Guide

 

Encrypted messaging apps have become essential tools in the age of cyber threats and surveillance. With rising concerns over data privacy, especially after recent high-profile incidents, users are turning to platforms that offer more secure communication. Among the top contenders are Signal, Telegram, and WhatsApp—each with its own approach to privacy, encryption, and data handling. 

Signal is widely regarded as the gold standard when it comes to messaging privacy. Backed by a nonprofit foundation and funded through grants and donations, Signal doesn’t rely on user data for profit. It collects minimal information—just your phone number—and offers strong on-device privacy controls, like disappearing messages and call relays to mask IP addresses. Being open-source, Signal allows independent audits of its code, ensuring transparency. Even when subpoenaed, the app could only provide limited data like account creation date and last connection, making it a favorite among journalists, whistleblowers, and privacy advocates.  

Telegram offers a broader range of features but falls short on privacy. While it supports end-to-end encryption, this is limited only to its “secret chats,” and not enabled by default in regular messages or public channels. Telegram also stores metadata, such as IP addresses and contact info, and recently updated its privacy policy to allow data sharing with authorities under legal requests. Despite this, it remains popular for public content sharing and large group chats, thanks to its forum-like structure and optional paid features. 

WhatsApp, with over 2 billion users, is the most widely used encrypted messaging app. It employs the same encryption protocol as Signal, ensuring end-to-end protection for chats and calls. However, as a Meta-owned platform, it collects significant user data—including device information, usage logs, and location data. Even people not using WhatsApp can have their data collected via synced contacts. While messages remain encrypted, the amount of metadata stored makes it less privacy-friendly compared to Signal. 

All three apps offer some level of encrypted messaging, but Signal stands out for its minimal data collection, open-source transparency, and commitment to privacy. Telegram provides a flexible chat experience with weaker privacy controls, while WhatsApp delivers strong encryption within a data-heavy ecosystem. Choosing the best encrypted messaging app depends on what you prioritize more: security, features, or convenience.

Twitter Launches End-to-End Encrypted Messaging Services


Twitter has become the newest social media platform to be providing encrypted messaging service.

End-to-end Encryption 

Direct messages delivered on the platform will be end-to-end encrypted, i.e. private and only readable by the sender and receiver. However, Chief executive Elon Musk has warned Twitter users to “try it, but don’t trust it yet,” taking into account that it is only an early version of the service.

Only users of Twitter Blue or those connected to verified Twitter accounts are currently able to use the service, which is not yet available to the general public. Additionally, users can only send text and links in conversations for now; media attachments cannot yet be sent.

In a post on its support site, Twitter writes “It was not quite there yet” with encryption. "While messages themselves are encrypted, metadata (recipient, creation time, etc) are not, and neither is any linked content[…]If someone - for example, a malicious insider, or Twitter itself as a result of a compulsory legal process - were to compromise an encrypted conversation, neither the sender or receiver would know," it further read. 

Online Safety Bill Criticized 

Musk indicated his plans to make Twitter into a "super-app" with many features when he purchased it in 2022. There is not really a similar platform in the West to China's super-app WeChat, which can be used for anything from social media and restaurant ordering to payments and texting.

Since then, he has made a number of significant modifications to the social network, such as the addition of a subscription service and the elimination of the previous version of Twitter's blue tick badges, which were designed to combat the spread of disinformation.

For a long time, many Twitter users have demanded that the platform's private messaging function be made more secure. The UK, where the government's Online Safety Bill would impose additional rules for social media companies, reportedly in an effort to safeguard youngsters from abuse, may find Mr. Musk's timing unsettling.

Messaging services WhatsApp and Signal have both criticized this part of the Online Safety Bill, which is presently making its way through Parliament.

They expressed concerns that the legislation might weaken end-to-end encryption, which is seen as a crucial tool by privacy activists and campaigners.

Following this, heads of the two messaging platforms signed a letter demanding a rethink over the bill. According to them, the bill, in its current form, opens the door to "routine, general and indiscriminate surveillance" of personal messages. In regards to this, a Home Office spokesperson stated, "The Online Safety Bill applies to all platforms, regardless of their design and functionality. Therefore, end-to-end encrypted services are in scope and will be required to meet their duties of care to users."

"We have made clear that companies should only implement end-to-end encryption if they can simultaneously uphold public safety. We continue to work with the tech industry to collaborate on mutually agreeable solutions that protect public safety without compromising security," he added.
