Dont Buy! Deleted all my data

The latest update, to version 3.4.2, cleared all of my data. The update stated "Minor bug fixed," and nothing more. Little did I know that after the updater, I would need a user login! I openned the app after updating, and none of my timesheets and invoices were there!
Appxy hasnt replied to my emails. The developers site doesnt list this app. There is no support.

i is jade about Hours Keeper Pro - Timesheet, Tracking & Billing, v3.4.2
