Is any personal data saved in Klok Mobile Cloud Sync?

When you register for the Klok Mobile (Beta) application, only the structure of your project list, the project names and an automatically 

generated unique identifier will be stored in Mcgraphix, Inc.’s cloud storage. Klok Mobile time entries are deleted from Mcgraphix, 

Inc.’s cloud storage immediately after you sync time entries with the Klok Pro Desktop application.
