How do you handle privacy of the data?

We built zCrowd to be deployed to the cloud.  So we can easily setup your own private instance on Amazon AWS or to your own servers. If you need HIPAA compliance then we would deploy it to your HIPAA servers.

How would you integrate to our system?

You can either send it to our JSON API or we can upload it as a spreadsheet.  The results can be picked up as JSON or sent back to you as a spreadsheet.

Can you integrate to Mechanical Turk?

Yes, that is our favorite public labor channel.
