Red04 adds screenshot guard and per-thread auto-clear

Two controls for the case the product could not previously cover: the person you are talking to.

Red04 protects a conversation from everyone except the two people in it. That has always left one gap — the other participant can photograph the screen — and the honest answer is that no software fully closes it.

Screenshot guard closes what can be closed. On both platforms the message list is excluded from screen capture and from the app switcher preview; on Android the window is flagged secure. When a capture is attempted anyway, the other participant is told.

Auto-clear is the blunter tool: set a timer per thread and messages are removed from both devices when it expires, whether or not they have been read.

What changed

• Message list excluded from screen capture and app-switcher previews.
• The other participant is notified when a capture is attempted.
• Per-thread auto-clear from one hour to thirty days.
• Auto-clear removes the message from both devices, read or not.

• ※Screenshot guard raises the cost of capturing a conversation. It cannot prevent someone photographing a screen with a second device, and we do not claim that it does.
