What it actually is

WhatsApp is a messaging app owned by Meta that uses end-to-end encryption, meaning messages cannot be read by WhatsApp, Meta, or anyone intercepting the connection. It requires a phone number to use, which limits random stranger contact compared to platforms like Telegram or Discord. The risks are group chats — anyone in a group can add your child to another group without permission, exposing them to unknown contacts. Disappearing messages can be set on any conversation. WhatsApp is widely used internationally and is the dominant messaging platform in many countries, so it's common for teens with international family or friends.
