friendly reminder, whatsapp is not end-to-end encrypted. WhatsApp and iMessage are vulnerable to law-enforcement real-time searches. WhatsApp shares message metadata with law enforcement agencies such as the Department of Justice. If legally required, or at its own discretion (such as for investigating Facebook leaks), it can provide critical location or account information, or real-time data on the recipients messaged a target subject.
