90% of top messaging apps now have AI data risks

A new study by Surfshark finds 90% of top iOS messaging apps include AI tools that could expose private data. Signal uses quantum-secure cryptography and collects only phone numbers. Meta's Messenger and LINE collect vast user data for advertising and tracking. Nine out of ten apps offer end-to-end encryption but AI features undermine privacy protections. The study analyzed 35 specific data types from Apple's privacy framework.
