/**
 * flatpak_user_data_delete:
 * @app_id: the application ID
 * @cancellable: (nullable): a #GCancellable
 * @error: return location for a #GError
 *
 * Deletes the data directory for @app_id in the current user's
 * <filename>~/.var/app</filename> and resets its permissions in the current
 * user's permission store. This affects only the calling user, regardless
 * of whether the application is installed per-user or system-wide. The
 * application does not need to be installed.
 *
 * If resetting permissions fails after the data directory has been removed,
 * the function returns %FALSE. It can be called again to retry the permission
 * reset.
 *
 * Returns: %TRUE on success, %FALSE on failure
 *
 * Since: 1.19
