Migrate from WhatsApp? This data is collected by Telegram and Signal | Digital Trends Spanish

Do I stay or do I leave WhatsApp? This seems to be one of the most recurring questions from millions of users in early 2021, after the messaging application announced new terms of use, which will allow it to share information with Facebook, its parent company.

The changes, which will take effect from February 8, 2020 and which some users have described as an ultimatum, have caused an incipient migration to other competing platforms, such as Telegram or Signal, considered more secure and less invasive in terms of Of privacy.

WhatsApp was forced to clarify that the changes seek to facilitate interaction with companies that market their products through the platform, but that the new conditions do not mean that it will have the power to read messages.

Beyond the advantages and functions of each of these platforms –whose details are available in this comparison–, do you know exactly what data each one of them collects and what are their characteristics in terms of security and privacy?

The Protected Data Foundation, a private organization dedicated to promoting privacy rights online, prepared a comparison of the information these applications collect and a summary of the main security features.

In terms of security features, the entity highlights that Signal has the advantage of offering end-to-end encryption throughout the platform, unlike WhatsApp (which only has on the app) and Telegram (only in private chat).

It also warns that WhatsApp requires sharing contacts, unlike Telegram or Signal. And that these two applications allow blocking the screenshot of chats, a feature that the Facebook service lacks.

Although the Foundation clarifies that it recommends Signal, because it offers a “private and secure” messaging service, it is best for users to make their own decision after analyzing this data.
