End-to-end encryption explained (plain English)
Kissend is end-to-end encrypted private web chat. Here is what that means — and how username-only identity keeps your number private.
What end-to-end encryption means here
End-to-end encryption means your message content is meant for the two people in the thread. Kissend is built as completely private 1:1 web chat with E2E encryption as a core promise — not an optional upgrade.
That pairs with username-only identity instead of phone-number contact sync, so your real identity is not revealed to others through your number.
Why username-only identity matters
Many messengers ask for a phone number and then unlock contact discovery. Kissend does not. You chat with a username, so strangers cannot tie your conversation to your personal number.
That is the quieter model: end-to-end encrypted messages, plus an identity that does not expose your phone number.
Why device habits still matter
Encryption protects message content in transit and at rest in the product sense, but someone looking at an unlocked screen can still see an open chat. Screenshots and forwards remain human choices.
Kissend pairs end-to-end encryption with app lock, hidden chats, and disappearing messages so everyday privacy is easier to keep.
Private chat in the browser
Open a private thread without an app install, connect by username, and use privacy controls when you need them. Read the security page for more detail, then open Kissend when you want a quieter private thread.
