Telegram and WhatsApp: Which is better for privacy?

In today's digital age, privacy has become a central and critical issue for users of messaging applications. With growing concerns about the security of personal data, it is crucial to choose platforms that offer strong protection and confidentiality guarantees. Telegram and WhatsApp, two of the most popular messaging apps in the world, have been the subject of frequent comparisons in terms of security and privacy. This comparison not only helps users understand the differences between both platforms, but also allows them to make informed decisions about which may be the best option according to their privacy and security needs.

In this article, we will explore in depth how Telegram and WhatsApp approach protecting the privacy of their users, highlighting their differences in terms of encryption, data storage policies, and security features. By understanding these features, you will be able to make more informed decisions about which messaging platform best suits your preferences and digital security needs.

Privacy and Data Collection Policies

What information do Telegram and WhatsApp collect?

Both Telegram and WhatsApp collect certain personal data from their users, although there are significant differences in how they handle this information.

Telegram: Telegram collects data such as your phone number and contact list from your mobile device. However, Telegram offers additional privacy options, such as the ability to register and use the app without providing your real phone number, using a username instead. This offers an additional level of anonymity for users who prefer not to share their personal information directly. Additionally, Telegram stores messages in the cloud, allowing them to be accessed from multiple devices, but also raises considerations about the security of this stored data.

WhatsApp: WhatsApp also collects similar information, such as your phone number, your phone's contact list, your message history and call logs, among other data. For example, when you sign up for WhatsApp, the platform requests your phone number to create your account. This information is used to facilitate connection with other users and to send notifications related to the application. Additionally, WhatsApp uses end-to-end encryption to protect your messages and calls, meaning only you and the recipient can access the content of your conversations.

How do Telegram and WhatsApp use user data?

Both platforms use user data differently, reflecting their privacy policies and how they manage personal information:

1. Telegram:
   • Data storage: Telegram claims that personal data, such as phone numbers, contacts, and message logs, is stored in encrypted form on its servers.
   • Data Usage: It uses data to offer and improve its services, such as message delivery, cloud storage, and personalization of the user experience.
   • Transparency: Telegram offers privacy options, such as secret chats, which provide an additional level of security through end-to-end encryption.
2. WhatsApp:
   • Facebook Property: WhatsApp belongs to Facebook and shares some information with this company, although it claims to have end-to-end encryption for messages.
   • Data collected: Collects information such as phone number, profile information, app usage, IP address, and location (if allowed).
   • Data Usage: Uses the data to operate and improve the service, display personalized ads on Facebook and other company services, and for other business purposes.

In our opinion, Telegram tends to focus more on privacy and user control over shared data, while WhatsApp, although offering end-to-end encryption, is more integrated with Facebook's data structure.

Message Security and Encryption

What type of encryption do Telegram and WhatsApp use?

Both platforms use end-to-end encryption to protect the privacy of user communications, but there are differences in how they implement this encryption:

1. Telegram:
   • Telegram offers two types of encryption:
     • Encryption in Normal Chats: It uses a proprietary encryption called “MTProto.” This encryption is not open source, which has led some security experts to question its robustness and transparency.
     • Secret Chats: For those users who want an extra layer of security, Telegram offers secret chats. These use end-to-end encryption based on the MTProto protocol, which allows users to verify encryption keys with each other.
2. WhatsApp:
   • WhatsApp uses end-to-end encryption based on the Signal Protocol. This encryption ensures that only the senders and recipients of the messages can read their content, even WhatsApp and Facebook do not have access to clear text messages.
   • This type of encryption is considered one of the most robust and widely accepted due to its transparency and security.

Are chats on Telegram and WhatsApp safe?

For this question, our personal answer is yes, although we lean more towards Telegram for its implementation of secret messages, read on and learn how they work. Chats on Telegram and WhatsApp are considered secure due to the implementation of end-to-end encryption. Here I explain in more detail:

1. Telegram:
   • In normal chats, Telegram uses a proprietary encryption called MTProto. Although it is not open source and has been the subject of debate about its robustness, Telegram ensures that this encryption protects end-to-end communications.
   • For greater security, Telegram offers the option of “Secret Chats”. These use end-to-end encryption based on the same MTProto protocol, but with the ability to verify encryption keys between users to ensure the integrity of the communication.
2. WhatsApp:
   • WhatsApp uses the Signal protocol to encrypt messages end-to-end. This protocol is widely recognized for its security and transparency, as it ensures that only participants in the conversation can read messages, including WhatsApp and Facebook.
   • End-to-end encryption means messages are protected during transit between devices and on WhatsApp servers, where even WhatsApp cannot decrypt the content.

Privacy and Settings Options

What privacy options do Telegram and WhatsApp offer?

Telegram and WhatsApp offer various privacy options for users. Here we detail some of the main characteristics of each one:

Telegram:

1. Secret Chats: This feature allows users to have conversations that are protected with end-to-end encryption. In addition, it offers the option to self-destruct messages after a certain time.
2. Key Verification: In secret chats, Telegram allows users to verify their contacts' end-to-end encryption keys to ensure that the communication is secure and is not being intercepted.
3. Control over Messages: Users can edit or delete sent messages, both for themselves and for all chat participants, offering greater control over the privacy of shared information.
4. Profile Privacy: Telegram allows users to control who can see their phone number and who can find you through contact search.

WhatsApp:

1. End-to-End Encryption: All messages on WhatsApp are end-to-end encrypted, meaning only senders and recipients can read messages. Neither WhatsApp nor third parties can access them.
2. Profile Privacy Settings: Users can control who can see their profile picture, status, and last time they were online. They can also decide whether they want to share their information publicly or only with their contacts.
3. Contact Blocking: WhatsApp allows you to block specific phone numbers to avoid receiving messages or calls from unwanted people.
4. Two-Factor Authentication: For an extra layer of security, users can activate two-factor authentication on WhatsApp, which requires an additional code when signing in on a new device.

Is it possible to hide online status on Telegram and WhatsApp?

On Telegram and WhatsApp, it is possible to control the visibility of online status in different ways:

Telegram:

• Hide Last Connection: In Telegram, you can adjust who can see when you were last online. You can choose between everyone, my contacts or no one. This setting is located in Settings > Privacy & Security > Last Seen.
• 'Administrators Only' Mode: In Telegram groups, you can activate 'Administrators Only' mode, which hides the last connection from all group members except administrators.

WhatsApp:

• Hide Last Seen Time: In WhatsApp, you can configure who can see the last time you were online. The options are everyone, my contacts or no one. This setting is found in Settings > Account > Privacy > Last seen time.
• 'Single Line View' Mode: You can set WhatsApp to only show a line of text when you're online instead of showing the exact time.

In both cases, these options allow you to control the privacy of your online activity and decide who can see when you are active in the app. Go to TELEGRAM DESKTOP.
