I used whatsapp before when I was on Malaysia since its their go to app for socials but I didnt like it compared to messenger of facebook. It seems theres so much suspicious on their apps. Probably due to their unfiltered system. I believe this app is a Chinese Product if Im not mistaken.
Actuallt I prefer discord or telegram over this app.
The app is technically a Chinese product because it can gather and share user data with Meta (formerly Facebook) for analytics and advertising purposes, making it not a fully end-to-end encrypted platform. Their end-to-end encrypted service is not guaranteed to work even if they are able to share such information.
