Hello, everyone! This time, we've looked at the most popular messaging apps to see how well each one actually protects your privacy and keeps your data secure.

Methodology and sources

For this study, 10 iOS messaging apps were examined: the pre-installed Apple Messages App — which is likely used by most Apple device owners due to its default presence — and the top nine most downloaded apps in 2025, according to data provided by AppMagic. MAX was excluded from the analysis because it is not available in the US Apple App Store, which is used to review app privacy practices. The selection criteria from AppMagic included the category (Social Networking), tag (Messenger), geography (Worldwide), store (iPhone App Store), and year (2025).

To evaluate the privacy practices of these apps, five criteria were selected. First, we examined the type of encryption employed, whether quantum-secure or not. This indicator delves into encryption, prioritizing whether cryptography is quantum-secure rather than just checking for end-to-end encryption. The default layer isn't enough, as quantum threats could potentially break through other encryption methods. That's why only those with quantum-secure levels of security earn the highest score.

Second, we looked at the number of data types the app may collect. This indicator assesses the data collection practices of analyzed apps, scoring them based on how many of the 35 data types listed in the Apple App Store they may collect. Collecting more data types increases privacy risks, for example, in the case of a data breach, which is why a higher number of collected data types leads to a lower score.

However, the total score for the app also includes two additional indicators: one for data collected for tracking purposes and another for data collected that is not related to app functionality. This approach provides a balanced view of data collection practices by not focusing solely on the number of data types collected, acknowledging that some are essential to the app's functionality. And fifth, we evaluated whether the app integrates AI features.

These factors illustrate each app's privacy-related activities and contribute equally to the final score. The scores of each analyzed app were then categorized into five levels, ranging from high to low, to indicate their commitment to user privacy and security.
