+**Important: Enable Local File Sync**
+To use local file sync, you need to manually connect the `home` interface:
+
+```bash
+sudo snap connect superproductivity:home
+```
+
+**⚠️ Snap Data Persistence Warning**
+When uninstalling the snap package, all user data (tasks, projects, settings) stored in `~/snap/superproductivity/common/` may be removed. Always export your data before uninstalling. Consider using Flatpak, AppImage, or .deb packages if you prefer data to persist in the standard `~/.config/` location.

+For more details, see [issue #6031](https://github.com/super-productivity/super-productivity/issues/6031).
