Some Q features run calculations on our servers on the Internet. These calculations transfer an encrypted copy of your data to those servers.
If this is unacceptable then you can stop Q from contacting its R servers by blocking access to reusprod.displayr.com and r.displayr.com.
You will probably need help from your IT department to do this.
Warning: Features that use R are generally marked with an "R" icon in Q's menus. These R-marked features will not work if you stop Q from contacting the R servers.
