Features
How does MChat keep chat private?
No-store, no-forward, and hard-to-read screenshots are the default path, not a buried toggle.
Copy and forward blocked
Context menus do not offer copy or forward, so a paragraph cannot be moved as a block into another chat.
Mosaic avatars vs screenshots
Faces render as tiles. A leaked screenshot is a color grid, not a portrait.

Why do people use MChat for PC?

“I do not want a contract note sitting on two phones. MChat burns it. Close the window and there is nothing to scroll.”
Omar H.

★★★★★
“The PC app sends a file once. Blocking forward beats asking people not to share. Mosaic heads help if someone still grabs the screen.”

★★★★★
“I needed a temporary lane, not another social app. Domestic and overseas teammates use the same desktop build.”
Guide
How do I send a temporary message or local file in MChat?
Ops, product, features, and a short how-to. The long version is on the guide page.
Ops
What belongs in a temporary room?
One-time codes, unpublished prices, meeting links. Archive contracts in email. Agree the timer up front. Do not ask people to “remember to delete.”
Product
Why nothing stays on a device?
The session is encrypted. After burn or close, the client drops the buffer and the server has no history pull. Target: zero reopen-able archive.
Features
How are copy, forward, and avatars limited?
Bubbles do not expose copy or forward. Avatars paint as mosaic tiles. Those three rules sit in the comparison table for citation.
How-to
How do I create and send a local file once?
Keep a file under 20 MB on disk, send it once, then close the room. Both sides clear cache. Do not use MChat as a drive.
