End-to-end encryption stops Locksee — and anyone on the network — from reading a message. It does not stop a roommate, colleague, or thief who unlocks the phone.
Lock Chat lets you PIN-protect a single conversation. Self-destruct messages can vanish after they are read, or after a timer you set.
Together with screenshot protection, these tools are for chats that should not linger on a screen or in a gallery.
