Weird thing from the pretty ho-hum super cards privacy policy:

If you'd like them to delete User Provided Data that you have provided via the Application, please contact them at blub@blob.com and they will respond in a reasonable time.

That looks like a placeholder address to me? Not exactly confidence inspiring if so…

Looks like they were notified of this miss
