Anti-Mod Functionality
| Feature | Technical Behavior |
|---|---|
| Anti-Message Delete | Prevents message removal on the client side when a sender deletes a message. Deleted messages are restored upon reopening the chat. Note: Server-side deletion prevents quoting or forwarding these messages. Messages are stored in the local cache; clearing the app cache will remove previously "saved" deleted messages. |
| Anti-Disappearing Media | Bypasses timers for view-once or self-destructing photos and videos. Media remains viewable indefinitely regardless of the sender's settings. |
