Comparison of Popular Messaging Apps

Let's compare the most commonly used messaging apps in daily life in simple terms. Understanding the strengths and weaknesses of each app helps you make the right choice.

WhatsApp: The most used app worldwide. Offers secure encryption (E2EE) but is owned by Meta (Facebook). This means your data can be used for advertising purposes. Also, backups in the cloud may be unencrypted.

Telegram: Fast and user-friendly. But there is no default encryption. Only 'secret chats' are encrypted with secure encryption (E2EE). Normal chats are stored on servers. This is a security shortcoming.

Signal: Open source and non-profit. Offers the strongest secure encryption (E2EE). Doesn't even collect metadata. However, the user base is smaller compared to others.

iMessage: Secure between Apple devices. But when messaging with Android users, it falls back to SMS, which has no encryption. Backups may be unencrypted in iCloud.

In summary, for secure messaging, pay attention to: secure encryption (E2EE), open source code, zero data collection, and a strong privacy policy. Choose apps that meet these criteria.
