As of Tizen 4.0, it is required by law to notify the user about personal information used in the watch face and how the user can determine whether or not to allow access to personal information during app launch. A device using Tizen 4.0 or later must generate a separate .tpk file for this purpose. The GWD tool now provides an option to generate separate .tpk files for version 3.0 and earlier and version 4.0 or later.

When uploading a watch face to Seller Portal:
- Upload a file with _TW4 postfix for devices using Tizen 4.0 or later version.
- Upload a file with _TW3 postfix for devices using Tizen 3.0 or earlier version.
- To support all devices, upload both files.
