End to end encryption means it can be trained on your inbox, especially locally. It’s not encrypted at rest on your side, else you wouldn’t be able to read it.
That’s why Facebook’s whole “WhatsApp is e2e encrypted, we can’t see anything” is and was a whole farce. They wouldn’t even make the claim in court. People even proved that they could exfiltrate data from WhatsApp after it made it to a users phone over to the Facebook app and boom, e2e didn’t matter at all.
You’re welcome. Honestly I wanted to point it out cuz I hate Facebook and WhatsApp 😂
