Saves all data. Any and all data you give them they can sell. I tried to contact to remove my info after using them for covid testing. It is virtually impossible. They tell you they will send an email with a link. That by clicking that link you can stop the continual use of your info.... That's a lie. No email, not return contact and they will tell you that when you try to call in for help. Go to a testing site and save yourself this trouble.
