Jeff wants to know if WhatsApp is private. He's concerned that Facebook gets his data. Leo says that WhatsApp does share user information with Facebook. But if he's concerned about that, there are other options. Leo dislikes Facebook so much, he doesn't use any of their apps.
Telegram is a really nice choice. It's free and secure. If he's looking for REAL privacy, then there's SIGNAL. They don't share any personal information. What about LINE? Leo says that Line is very popular in Japan. Then there's Discord.
