Tools that help on shared devices
- App lock — PIN-protect the Kissend session.
- Hidden chats — tuck sensitive threads away, with optional decoy PIN.
- Disappearing messages — send details that should not linger.
Shared-device privacy
Private chat on a shared device
Encryption protects message content in transit and at rest in the product model — but a borrowed phone or open laptop is a different risk. Kissend adds app lock and hidden chats for that moment.

Does app lock replace a phone passcode?
No. Use both. App lock adds a Kissend-specific PIN when someone already has device access.
What is a decoy PIN?
Optional unlock that opens an empty inbox instead of your hidden chats. See hidden-chats.html.
Can I use Kissend in a hotel or library browser?
Yes — it is browser-based. Prefer logging out on public machines and using app lock on personal devices you share.
