QR Studio Pro

Your license, your Macs.

See which Macs use your QR Studio Pro key, and deactivate one you no longer use. You can do the same in QR Studio, in Settings › License.

It's in the email from Dodo Payments you got after buying.

This page sends your key and email to QR Studio's license service to find your Macs. It doesn't keep them in your browser. Lost your key? Write to support@vpolabs.com from the email you used to buy.
