WhatsApp's end-to-end encryption genuinely protects your message content, but everything around it — who you talk to, when, how often, your contacts, your device — flows to Meta and is used to build ad profiles across Facebook and Instagram. You can't opt out of the Meta data sharing and still use the app.
