-To uninstall the app files while keeping your config, knowledge, presets, assets, history, and cache:
+To uninstall, remove podcli and everything under its managed folder — runtime, models, cache, **and your config, knowledge, presets, assets, and history**:
 
 ```bash
 podcli uninstall
 ```
 
-Add `--purge` if you want to remove the entire managed podcli folder, including user data.
+This removes all managed data by default. Run `podcli uninstall --dry-run` first to see exactly what will be removed, and back up the folder if you want to keep any of it. (`--purge` is kept as a no-op alias.)
 
 **Optional**, for AI clip suggestion and the PodStack slash commands: install
