The process of scrambling data so that only the intended recipient can read it. End-to-end encryption means even the platform itself cannot see the content of your messages.
In plain English
The process of scrambling data so that only the intended recipient can read it. End-to-end encryption means even the platform itself cannot see the content of your messages.
Why it matters
Encryption protects privacy and is the default on apps like WhatsApp and iMessage. It also makes some safeguarding work harder, because abusive messages cannot be scanned by the platform. Parents should know that screenshots, device-level checks, and conversation remain key safeguards.
