Verdict: WhatsApp offers excellent message encryption but shares extensive metadata with Meta's advertising ecosystem. The content of your messages is secure, but who you talk to, when, and how often is not.
WhatsApp is the world's most popular messaging app with over 2 billion users. It features end-to-end encryption by default for all messages, powered by the Signal Protocol. However, its ownership by Meta raises significant metadata concerns.
