An unpopular opinion, but I will never trust WhatsApp. In fact, I frequently will evangelize against using it. Never trust a "secure" app which allows a company to "recover" your data. True end-to-end encryption is entirely in the hands of the user. No metadata, no tracking, no identification, and certainly no server-side "recovery." You are much better off using Signal, Telegram (with encryption enabled), Element (Matrix), SimpleX Chat, or a Nostr client.
