WhatsApp’s encryption: What’s really private — and what’s not

[ed]

While WhatsApp says your messages are end-to-end encrypted using the Signal Protocol, that doesn’t mean all your data is private.
The company admits that metadata — who you chat with, when, and how often — isn’t encrypted. Backups of your chats may also remain unprotected unless you enable encryption manually.
And while WhatsApp says it doesn’t sell your data, it does share information across Meta platforms “to improve and support” its services.

Encryption is strong, but metadata leaks still expose a lot. ️

Privacy isn’t about messages alone — it’s about the ecosystem handling them.
