WhatsApp's end-to-end encryption is designed to secure messages against snooping. The app also comes with multiple security features that keep your messages protected. Enabling 2FA and fingerprint protection can help to protect your WhatsApp account from unauthorized access. That said, WhatsApp itself still collects a lot of your metadata (such as the time of communication and contact details). The platform could potentially share your information with authorities under specific legal circumstances — for example under warrants or subpoenas.
